Alloy 304 / 1.4301
The stainless austenitic chromium-nickel steel 1.4301 has good corrosion resistance (especially in natural environmental media and during absence of significant chlorine and salt concentration and sea water) and weldability. Check applications with acids specifically. In welded condition 1.4301 is not resistance to intergranular corrosion.
