SUS304N2 (18Cr-8Ni-N-Nb) is an austenitic stainless steel produced in Japan. It is obtained by adding N and Nb to SUS304 steel. Its performance is the same as SUS304N1 and can prevent the decrease in elongation. , it can also increase the strength and also reduce the thickness of the material. The use of SUS304N2 stainless steel is the same as the use of 304N1 steel.
