Stainless steel austenitic non-magnetic steels of the J 200 series were developed as an economical alternative to W.Nr. 1.4301 (AISI 304).

The basic chemical composition of the J 200 series with 15.5-19% Cr and 1-5% Ni is suitably modified by the alloying elements Mn, Cu, N2.
The result is J 200 series steel with parameters comparable to W.Nr. 1.4301 and even more suitable for certain uses.

J4 is 50% stronger than 304! The chromium content is also slightly lower, but as seen from the PRE, this is compensated to a large extent by increased nitrogen.

 

J4 is 50% stronger than 304
