SS 202

Hello, nilayveera. How is the electrical lug manufacturing business these days?

SS202, eh? Can you tell us if it is austenitic?

Well my Machinery's Handbook - 22nd edition page 2104 would say yes its austenitic.

and my Introduction to Phyiscal Metalurgy - second edition Page 371 states that these types of Stainless steels is essentially nonmagnetic.

But cold working, it can develop a wide range of mechanical properties and can become slightly magnetic. And on page 373 it states its general purposelow nickel equivalent of 302; Ni partial replaced by Mn.

I believe some ss bolts are made from 202 or 302 SS

So basically, yes it can be. not knowing any other information of this material.

^{he's lucky I had to look for simular stuff last week}

salam allikum, it is known that austenitic stainless steel is non-magnetic. Herein below the physical and chemical properties for this material AISI Type 202

Good day, salam allikum

Your statement

it is known that austenitic stainless steel is non-magnetic.

Sounds like a definite answer, considering nilayveera asked a vague question without any accompanying information, that could be answer differently.

Or should I say a vague/typical answer to a vague/typical question would be more fitting.

Should have nilayveera put a magnet to it.

p911

the pratical experince is, SS 202 has properties to rust in long run. We want to use this steel in a part of electrical transformer so am concerned with the magnetism.

i did not by any means find this simple question vague.

Hello nilayveera:

i did not by any means find this simple question vague.

Problem was it was too simple. And to me it would be vague, you are asking for a definite yes/no answer to a question that could have a number of possibilities. As I stating in the earlier post it seems that it would depend on how the material is worked. with the heat sheet or mill spec. it would help.

And as the guest stated it was a definite answer and I disagree with that from my post which I listed my reference, that answer should not be definite with out more information of the material. Do you have heat sheets with that?

And since it does oxidize it may have ferrite in it to be magnetic. They use that because of reduce galling. Tensile strength is reduced, but so is the facturability of the material.

Did you put a magnet on it?

In the mean time I'll look through my references to see if I can come out with a more definite answer, but with out more info, I can't gaurantee.....

Nice links, but thats why it reenforces the reason you need the heat sheet or mill spec papers, page 5 on your last link shows Fe. As well as other aloys replaceing Ni due to the shortages.
