stainless steel identification
(OP)
I have attached chemical and hardness specifications for two materials i have named old and new.
The hardness was done on 0.5mm thick plates. Why would the chemical analysis be in spec and the hardness be outside spec. Note maximums are given unles a range is given in table below.
C Cr Ni Mo HV
new 0.11 17.43 6.973 0.208 484
old 0.04 16.76 10.3 2.293 115
301 0.15 16-18 6-8 -- 392-160
302 0.15 17-19 8-10 -- 211-160
316 0.08 16-18 10-14 3-2 230-156

RE: stainless steel identification
What load did you use for the hardness test? Half a millimeter is pretty thin for a hardness test unless you are using surface hardness or microhardness.

How magnetic is the new one?
You don't plan on welding this do you?
