Mild Steel VS Hardened Steel - 100 ton crush test

[@curtisroberts9137]

I was a gunsmith and machinist for 14 years as well as auto technician and now a full time welder. I've always studied metalurgy a little in order to be better at my trades. Hardened spring steel can be on of the most amazing metals. The amount of abuse a piece takes hulding up a 20 or 30k lbs on a truck for years at a time with all the vibrations and flexing. Blows the mind away! Cool video.

[@simcoespring]

Well said. 30k lbs bouncing around and the only difference between that and other metals is come carbon and some heat treating.

Hi c. Just wait untill you experience the new metals using graphine and nano particles. It amaze your mind , body and soul. You should look into graphine it's on the periodical chart.

[@dougpark1025]

Curious about tool steel. Might be interesting to throw a grade 8 nut in the mix. Also, try quench hardened spring steel. Harder, isn't necessarily stronger. One thing that is done in testing metal is to see what the tensile strength is by pulling apart a piece with a particular narrowed cross section. Not sure if you have the equipment to do that. I am always interested in metal failure.

[@simcoespring]

I wish I could do tests like that. I'm always worried about critical failure and shrapnel.

[@truckgotstuck]

That grade 5 stover / top-lock nut appears to be a class C which is a grade 8 equivalent. That would explain it being harder than the hex nut. It has 6 dots, a Class B / Grade 5 usually has 3 or less dots on the top. I sold a lot of nuts and bolts, and since you are interested, I thought I would share.

[@simcoespring]

Cool info. Now I have to look at all my lock nuts.

[@myinfo3406]

Just started watching some of your videos. You got a better press than we do. I work at a dealership too.

[@yowser8780]

Gave me the willies watching you destructively press steel. A guy was killed at a shop where I worked as a 'kid'. 250 ton vertical press, pushing out a stud with a short piece of round stock. Stud hung up and the round stock exploded and threw a chunk of shrapnel through his heart. He was dead before he hit the floor. Shop then put a steel protective guard around the press.

[@simcoespring]

yes and that is why you need to know about steel types. hard vs soft, stuff that squishes vs hardened steel. which is why you NEVER put hardened steel up against hardened steel.... Probably a hardened punch against a stud which is also a grade 5/8 hardened piece of steel. We always use mild steel or cast to press out parts that will squish or deform when we use it in the press. I use a ton of aluminum to press bushings in because of this very reason.

[@Chris_In_Texas]

I think you have found a new sideline business! Cool paperweights for the gear heads out of different metals or steels crushed together! Would be a cool conversation piece for a desk! I know I would purchase one! Could do colors with brass for example into another metal. Would be great use for some of the scraps or extra nuts / bolts laying around and sell your masterpieces on the website store! 👍😁🍺

[@airpower7692]

Would like to see this retested after you get that mild steel red hot where a magnet won't stick then quench it

[@DirtRoadLanding]

Scott, can you do a test on how strong a weld is? Similar to your crush test of your axle lift kit but more concentrated on shear resistance of two welded pieces. Thank You.

[@simcoespring]

Interesting idea. I'll have to think about that one.

[@thomasglessner6067]

Where do you buy spring material from? Do you know what the chemistry of the spring steel is? Love the content. It's amazing the disassembly takes so much work. I'm sure when assembling a new suspension everything just goes together like it should. I have a great respect for your knowledge and skills. Also like the pit you work in. Wish I had one to call my own. Thank you for sharing with us.

We have a leaf spring supplier. Spring steel is 5160, you will have to look up the chemical materials online.

[@mikeznel6048]

Hey I have a question. I have a 1999 Chevrolet C3500 truck with a 9 leaf spring pack. How much would it cost to have a new set made? The rear eye on the right spring is cracked and I’ve been looking for a new set so I can the truck to it’s full potential.

[@simcoespring]

sounds like a cab and chassis truck. Sometimes you can just get a main leaf and just replace it.

[@yafois988]

Maybe a Rockwell hardness punch test on things would help demo their hardness?? Some of those would make great earrings for a female welders that smokes cigars and wears terminator sunglasses at the beach.. Good stuff here..

[@yt66228]

[@wheelitzr2]

[@simcoespring]

[@crf50crazy]

I just found your channel and love it. I have a question, I have a 2001 F350 dump bed truck, how often should springs be replaced. I haul mulch and rocks Thanks

[@simcoespring]

keep an eye on the leaf springs. Watch for breakage. the 1999-2007 F350 pickup trucks are notorious for breaking leaves now because of their age. Keep an eye out for a broken leaf in the spring pack. If you break a leaf now, they are probably all close to breaking and you should just replace the whole stack. we usually look at age/mileage. If a spring has over 200,000km or 160,000 miles and is over 10 years old then you did pretty good with the leaf springs and if they start breaking you should probably replace the whole stack. However if you only plan on keeping it for a short while, or can't afford a whole new spring, you can just get a single leaf replaced and that should buy you some time. We also come across leaf springs that are worn out, sagged out, bagged out, unsprung, whatever way you want to call it. Sometimes if they just can't carry what they used to carry, then you can either put new leaf springs in, or add an extra leaf to the spring stack and replace the plastic pads and other hardware pieces and buy some more life out of them. So ya, lots of options depending on the age/budget/mileage and how long you plan to keep the vehicle will determine what you want to do with the suspension. **final note, if you have high mileage on an old vehicle and you need guaranteed use without a breakdown, sometimes a fresh set of springs and shocks will breathe new leaf into an older vehicle. rust buildup between the leaves and old shocks can really ruin a suspension even if nothing is broken.

[@crf50crazy]

Thank you for the great info! This truck has 115,000 miles. My f 250 has 175,000 miles. How much should I expect to pay to replace the springs? I have no clue who does that around my area, wish you were closer 👍🏼

@@simcoespring Really ?!? Then again, youre probably too busy working to be bothered. Seriously though, Id like to see some other types of metal get crushed, like some Aluminum etc to see how it forms under pressure, does it crack or flatten like a mud pie ? And does the temperature Rise when being under pressure, like an ice cube and how it melts when under pressure, All that good stuff ... For Science ! Cheers mate.

Hey man so I’ve been doing this kind of work for 5 years now my father 35 years and I feel I’m being underpaid, what’s the average hourly pay for you guys?

[@simcoespring]

that is a very loaded question. depends where you are located, what kind of work you do, do you own the business. how many years experience. if you want to discuss this in length, message me on Instagram @simcoe_spring

[@duranduran8361]

Dang I don’t have an instagram but it’s ok I was just curious. I’m in NJ got 5 years experience and we only do springs which include air ride, lead spring, bushings, king pins, chassi work, repairing and replacing leaf springs etc pretty much anything that has to do with springs on every type of truck from muscle cars to macs to ambulances.

[@duranduran8361]

It’s just suchhhh a hard and dirty job I feel like the pay should be so much more and no one else in my area does this kind of work so I was always curious to know how much other guys that do this same work get paid and btw I work for someone. They start us at 17 an hour rn I’m making 20 which is impossible to live off of in the east cost but if you don’t feel comfortable talking about pay on here that’s totally fine I was just curious and unfortunately I don’t have an instagram so no biggie but anyways I like your videos it’s cool to see how other guys do this type of work, by us we don’t have a dig out so we gotta crouch down or lay down to work after jacking up the trucks

[@henryD9363]

Very interesting and informative. Thank you. What I would like to see is take the bolt steel, heat it red hot, say on a sand platform, and then cover it with sand so it cools down slowly. Then do the same thing except quickly drop it into oil or water. Then of course do the test. I've always wondered why the welding of steel does not require annealing. I have no experience with it, but it seems to me that a welded seam would have different properties based on how quickly or slowly it cooled down. But no one ever discusses this. So I presume cooling down rate is not any kind of factor in terms of strength. I watch all your videos. They're fun and I learn a lot. Even though I'll never replace a spring, even on a clock!

[@jackdawg4579]

heat affected zones from welding are often the failure point further down the track, its also why cracks form just outside of the welded area. So that is why a welder / designer must choose type and locations of welds carefully to minimise such risk. it is not a good idea to weld across a draw bar on a trailer for instance. Large elements that are welded are usually preheated, then cooled slowly after welding.

[@simcoespring]

I have an idea about that same process for leaf spring eyes when we roll them. One quenched in water, oil, annealed in sand. One annealed in the forge. One normal one and one from the factory. However I need to build a safety cage around the press. So that wont happen for a while.

[@wrathmachine7609]

I wonk on maintaining dump trucks and on the U channel frames it says “Do not heat or weld, hardened and heat treated”

[@davids1033]

Mild steel is ductile.

[@billhamilton2366]

All you are displaying is the modulus of elasticity of different alloys of steel. It is not a head to head comparison and is flawed in that the specific chemical composition of each sample is unknown. Mild steel is not a “alloy” steel because it contains low amounts of carbon and no other elements. In and of itself is ductile and easily machinable. In other words it is soft with no elements to assist strength.

[@simcoespring]

Yah exactly. Big press go squishy. Just having sine fun playing with different materials. I actually didn't know that our deep nuts where the same material as a regular hex nut. So I learned a few things.
