SUS304N2、XM21、S30452

Stainless steel: SUS304N2

characteristic:

SUS304N2 stainless steel (18Cr-8Ni-N-Nb) Japan's SUS series austenitic stainless steel. Adding N and Nb to SUS304 steel makes it have the ability to increase the strength while suppressing the decrease in elongation performance, and to reduce the thickness of the material The same performance as SUS304N1.

 

Scope of application:

SUS304N2 stainless steel uses the same as 304N1 steel.
