I as a carpenter worked with an old timer "millwright" that needed an extra set of hands just a touch more skilled than a laborer this one time. I work in semiconductor clean space construction and he insisted that we didn't need the fancy $250 an ounce lubricant on the threads what for saving money that's not his to save. Well the long story involved the steal equipment pedestal, core drill bits, a mag drill, taps, some red hot swearing and some smuggled in dawn dish soap that we use as lubricant whenever we need to cut stainless. And by "we" I mean "me" because at that point in my career I was still an apprentice and knew far more than the guy with the millwright book. It's amazing how many individuals of a skilled profession know less than the indentured tool carriers that are loaned to them from other trades. You stay right there captain boss man, I'll clean up after you.

Core Memory Activated: Back in my days as a nuclear plant operator in the US navy we had stainless infrequently operated primary coolant valves that had caps that fit over the entire bonnet assembly that were sealed with a self-presurizing metal o-ring. The valve caps themselves had acme threads to reduce the chance of galling, but every time the cap was removed we had to clean the threads and apply colloidal graphite (neo-lube) to both threaded surfaces and we had a special procedure for re-installation of the cap that basically said the cap must be spun on no faster than 30RPM until the surfaces mated the O-ring and then when torquing, 5 seconds per flat and 5 seconds between flats. We never had a galling incident but did have a scare when the brass insert that had the stem operating threads fail and the valve couldn't be shut. Thankfully it was part of a double valve isolation and the other valve was working properly.

We actually stopped using stainless steel bolts at our aquatic center. We switched to galvanized bolts because we were finding that the chlorine in the air and water were corroding the stainless bolts from the inside. We would find a stainless bolt with the head missing and the inside would be corroded away. Maybe it was the wrong grade of stainless. The galvanized seem to hold up better for our use and are much more apparent when bad
@Foxholeatheist9 ай бұрын
Stainless is only stainless when it has oxygen around it. Inside of a bolted connection with water (and especially chlorine/salt) in an anaerobic environment it will happily corrode away. This is a big problem on sailboats with stainless bolts penetrating a cored fiberglass surface. If the core material (often plywood or end-grain balsa) isn't sealed properly at the hole, water will get down in there and create a perfect environment for corrosion. The visible parts of the bolt will be shiny and lovely, but the part doing the work that you can't see is corroded away to nothing. Silicon bronze is a much better choice as it doesn't have this problem.

So for the military usage we supplied, the approved procedure is to use different alloys of stainless in the nut and bolt, they must both be passivated, and they get never-seize appropriate for the environment. Different alloys are less likely to self-weld to each other, the passivation layer prevents bare metal on metal contact, and the base of the never-seize (zinc or copper) provides a further layer of separation as well as a galvonic barrier.

The Galling problem is especially bad if the SS bolts and nuts are put on fast, as with a battery operated tool. My brother used to use SS bolts and SS nylon lock nuts and he had a failure rate of 10 - 20% where the bolt would seize, and you'd have to snap it off to remove it. Nickle never seize helped, but was not a cure. The only thing that really worked was to only use hand tools and put the bolt or nut on slowly. Interestingly, this type of condition, known as Galling, Friction welding, Cold welding happens in milliseconds and once galled, the fasteners can only be removed by cutting or snapping them off using great force with wrenches or ratchets. It only occurs, to my knowledge with SS, Titanium and Aluminum.

It's also exhibiting an excellent high temperature oxidation resistance _and_ resitance against cavitation erosion.

Be more worried that they're loose. When loose, you no longer have solely shear force on the bolt, which itself is highly damped by the friction between the bolted components.

Stainless steel has small burrs that heat up during tighting which is referred to as galling. Even going slow will seize the nut to the bolt before it gets tight. Little antiseize works perfect to avoid this.
@Jmoneysmoothboy9 ай бұрын
"Small burrs" heating up during tight-en-ing tightening is NOT referred to as galling. If it were "small burrs" then it would not be an issue because they would just snap off. The problem is that the surfaces are incredibly smooth and mate with close to 0 clearance and then torque is applied which gives negative clearance and just like in anime the surfaces realize they are one and cease to be separate.
@Hydrazine10009 ай бұрын
There is no heat involved. This is why "galling" is also often referred to as "cold welding". In direct metal-to-metal unlubricated sliding contact the thin surface oxide layers will break and the contact pressure will fuse the mating surfaces together. Fun story: the first cameras taken into space came back seized. Hard vacuum means that after sliding no protective new oxide layer would form on the stainless internals, so galling was the result. Hasselblad, the well known camera maker, had to gold plate the camera internals to prevent this from happening again.

18-8 or 304 Stainless and only tighten with hand tools, never used anti-seize on any hardware and never had a fastener seize up on me, I think it really comes down to heat during tightening (the hotter the bolt, the softer it gets and bam you have galling), this usually happens when tightened too fast, like if cross-threaded or with power tools! Aluminum tapped holes with SS fasteners into them can be quite tricky though, for that we helicoil the Aluminum first then we put the SS fastener in, prevents the two from galling together. Plus the Aluminum we use is Iridite coated, this also helps to prevent galling for holes that cannot be fitted with a helicoil. I mostly just work with SS fasteners from #0-80 up to 1/4-20 though, granted we use alot of them, for some of the radio systems we do, we usually have upwards of 100-200 screws per unit (lot's of tiny screws spaced very close together to prevent RF leakage), most of what we do is custom so it's all assembled by hand with a tiny hex screwdriver.

Learned this lesson over the summer building a boat dock at the beach. Spent a small fortune on 316 hardware. My question is how long will the 316 last bolted to aluminum bracing? I did have the aluminum structurally anodized. But I'm guessing it's only a matter of time before corrosion begins at the contact points. The structure is all FRP so no worries there.
@SeanBZA9 ай бұрын
316 will be fine, the aluminium will not. You need to use the right material to prevent corrosion, and thus inconel bolts in aluminium, and also a thread sealer to keep water away. 316 will however slowly corrode in salt water.

1.4401 or similar chrome+nickel+moly steel for stainless aquatic/marine applications, same goes for welds, those tend to self-disassemble if you use 1.4301 (18/10) or other cheaper stuff even if it's just your filler/electrode/wire. And stay away from any aluminium inserts and rivets, those act like artificial cathodes if used below the waterline and crumble faster than it took you to install them.

Before spacecraft hardware is brought into a cleanroom, it is precision cleaned to remove all surface contaminants and oils (these can later outgas in space and contaminate other pieces of hardware). I was once told an amusing story about this: an engineer was working on a test unit prototype and refused to wear gloves, stating that it wasn't flight hardware and the skin oils wouldn't matter. He developed the assembly procedure under this setting. Later in the mission, it came time for the *flight* hardware to be assembled; every single fastener on the system galled and stuck like crazy. The oils of the engineers skin had worked as an anti-sieze compound, preventing galling; when the flight hardware (which had been cleaned to spotlessness) was assembled, the metal immediately cold welded. I experienced this firsthand myself, when assembling a nitrous oxide feed system for an experimental rocket motor. I had plenty of experience with working with black steel pipe, and never had an issue with galling (as typically there was leftover cutting fluid from when I cut the threads.) We had just bought hundreds of dollars in stainless steel fittings for oxidizer compatibility, and meticulously cleaned them of any oils and greases. Imagine my surprise when, after threading everything together, I discovered that pretty much every single fitting had galled and destroyed threads.

Specifically austentic stainless. Austentite is the mostly non-magnetic crystal form usually encountered at the elevated temps used for annealing and quenching hardenable steels. Austentic SS alloys like 304 and 316 retain this lattice structure at low temperatures, it makes them tough even for crygenic use and extra corrosion resistant, but also gummy and only moderate strength. Martenistic(quench hardened, common in knives) and ferritic (basically like annealed common steel) SS aren't nearly so prone to galling.

Anti-sieze is really even more specifically for high temps when most greases will have boiled out, but it still works alright at room temp. Moly or graphite EP grease will also do the trick on austentic SS at modest temps, of course the torque spec will need to take the type of thread dope into account or you'll stretch her into bikini shape. This happened to the main pivot bolt on my trailerable sailboat keel. It was right froze in there(and may have had 100 pounds of keel still resting on it but the whole think had sat for 20 years prior.) so I cut off the bolt head intending to pull it through with the nut, but the nut started to gall, gave the threads some EP grease and it pulled out nice after that. (Pounding it through was not a viable solution because of space and likely mushrooming.)
