simple question on new carbon steel
(OP)
Hi i have a few general questions about a new carbon steel we are looking at for metal forming applications.
this steel is similar to most carbon steels used in automotive industries in terms of chemistry.
It is a new steel grade still under development, its classified as a High elongation, High Tensile/yield, isotropic steel, but it's not a HSLA steel.
From what I've been told, the most unique feature of this steel is the micro structure and heat treating capabilities, which i cannot elaborate on very much sadly.
after talking to the vendors metallurgist, he said that the phase of the metal is mostly austenite. Now I've been told that austenite is not magnetic, which is why most 300 series Stainless are almost completely non-magnetic.
now my question is, should i expect similar magnetic properties from this carbon steel, that is seen in 300 series stainless, before and after cold working? or will it most likely be highly magnetic before/after cold working? is it possible for a carbon steel to be non-magnetic?

They have a large amount of retained austenite but are still mostly ferrite.
These do end up fully magnetic.

They basically said it was made from recycled steel, and doesn't require any highly unique/difficult processes to make. They referred to it as an "Advanced High Strength Steel" (AHSS) and the micro structure as a "Mixed Microconstituent structure" of austenite and ferrite, which i am not very familiar with.
they claim that their new line of steel will reach elongations around 50% with tensile strengths over 1000 Mpa

My guess is it will be highly magnetic.
