Stainless steel rusts or tarnishes

  • Can you grind stainless steel, or do you use it to break the rust protection?

With stainless steel, the entire material is rust-free. Grinding shouldn't be a problem, here you can find some information about it: http://www.klingspor.de/html/index.php?site=3_21_63&lng=de You just have to be careful with the material, but that is yes actually taken for granted.

First prize for the funniest question of the day! My whole office is lying flat with laughter.

yes, in my opinion, you can easily process stainless steel. the fact is that, for example, good stainless steel pots are specially sanded on the underside and therefore cannot rust on their own. actually, stainless steel can't rust at all, I thought.

Stainless steel has no rust protection, the material is naturally corrosion-resistant. So you can sharpen it as much as you want. But high gloss is difficult to achieve, because you need a special device for. But if you want a matte surface, go for it.

"Before an office bends with laughter, it should also have an idea of ​​the matter!"
Steel does not rust if the chromium content is over 13%. A higher proportion of chromium also means better rust protection. The property of chromium atoms is that they form a layer like a color on the surface (explained quite simply). That is why the surface quality is important when grinding, as is the steel quality. If it is a steel with "just 13% chrome", the surface must be sanded as smooth as possible. My experience: a V2A steel that is only sawn off and remains rough sawn at the interface rusts after half a year in the open air.

Hello,

yes, stainless steel can also rust if you grind it.
But only if you overheat the material (turns brown or even yellow) or you put iron particles on the surface of your workpiece.
For example, if you have previously sanded steel with the grinding tool, you must never use it to grind stainless steel. If you use a brush, it must be made of stainless steel.
Good metal construction companies completely separate stainless steel processing from normal structural steel processing.
If you take this into account, an oxide layer will form again on the polished stainless steel surface after a few hours and the stainless steel will be corrosion-resistant.

There must be really stupid people, an entire office laughs itself to death at someone who seriously thinks about a thing and doesn't even have a clue of how stupid they are, embarrassing, embarrassing

Yes, stainless steel can rust and will even rust as soon as the so-called passive layer, e.g. sanded down or holes drilled (so-called plitting).
I hope idiots' office is not responsible for people and their health, that would make me very worried.

Stainless steel itself does not rust, neither V2A 1.4301 nor V4A 1.4571 or 1.4404 but the impurities on the surface. But that can be done with stainless steel stain, for example. Easily remove the Antox again. You should never work with abrasives that were previously used to process "black steel", i.e. normal steel, because the "ignoble" particles then nestle on the sanded surface and then evidently develop into superficial rust, but this has nothing to do with corrosion in the true sense of the word do that, as I said, is only superficial. When selecting the abrasives, also note that they are suitable for stainless steel. Not every abrasive has this property. Since high temperatures can not withstand grinding, the abrasive grains quickly "vitrify" and the abrasive actually only smears over the surface, takes nothing but heats it up so that in case of doubt it leads to the discoloration.
