SUS304N（304N1）、S30451、Z6CN19-09

Stainless steel: SUS304N1

Features and:

SUS304N1 national standard 0Cr19Ni9N is a nitrogen-containing stainless steel. Based on 304, S and Mn are reduced, and the element N is added to prevent plasticity and increase the strength of the steel. It also improves the resistance to pitting corrosion, crevice corrosion and interstitial corrosion.

Scope of application:

SUS304N1 is the most widely used as stainless steel, suitable for petroleum and chemical equipment. Suitable for manufacturing acid pipelines and containers.
