Specification (hardness) for stainless steel SUS 310 3/4 Hard

[Caine Lu]

Hi Guys ,

I have a product need to use stainless steel SUS 310 3/4 Hard but I can not find any spec for this material . I'm wondering if someone has this spec , especially the material hardness .

on the other hand , do you know who in USA or somewhere can supply this material in coil sheet metal . about 0.25mm thickness .

thanks!

Refer ASTM 240 for technical specifications

Check this for equivalent (foreign) standards

what does 3/4 hard means ... sorry this is my first time to see a 310 stainless steel calls out for this ...

They come in different grades from annealed, 1/4 hard, 1/2 hard, 3/4 hard to Full-hard. 3/4 hard refers to degree of hardening - refer to manufacturers details or specs for actual hardness.
