austenitic

Stainless steel cutlery is most commonly an 18/0 ferritic grade, but premium cutlery may be an 18/10 austenitic.

About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel.

Martensitic stainless steels are less corrosion resistant than austenitic steels and are ferromagnetic, but they're used for good reason.

It can't be hardened/tempered since it's austenitic, but maybe selective work hardening provides some benefits.

Kitchen knives are invariably martensitic, because ferritic or austenitic grades wouldn't hold a sharp edge.

My comparable obsession with austenitic steels has now gone fully virtual thanks to materials informatics.

Glass and austenitic stainless are both good candidates for that material.

But note that slight working like bending it a bit will only turn a small portion of it into martensite, most of it will remain austenitic.

The most corrosion-resistant of the common stainless steels are austenitic.

Aluminum, magnesium and austenitic stainless steel are also non-magnetic.

> The new technique involved repeatedly twisting a sample of 304 austenitic stainless steel in a machine in certain ways.

I thought that the Cybertruck alloy was an austenitic (non-magnetic) stainless steel.

The body panels are pretty thick, and they're made of an austenitic nitrogen steel -- a modified form of 316LN -- which should perform nearly as well as any "armor grade" steel alloy.

> "non-magnetic iron" Austenitic stainless steels are a thing.

Reviewing Musk’s public comments on Cybertruck online, Matlock surmises that the material is 'very likely a modified version of the lean-alloyed austenitic 301 alloy.'" Two other things line up for me: the rate of rust is right and I think if they were using 304 they'd want to advertise it as 304, not 30X.

Austenitic steel is not iron, it's iron + carbon.

Austenitic stainless steels have various advantages, especially that they are much more suitable to cheap processing by plastic deformation, so nowadays they are much more widely used than the kind of stainless steel invented by Brearley.
