1.4466 stainless steel bar

310MoLN (1.4466) Stainless Steel Round Bar is a high-alloy austenitic stainless steel designed for superior corrosion resistance in extremely aggressive environments. With elevated levels of molybdenum (Mo) and nitrogen (N), this grade offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-containing media.

It is widely used in demanding industries where standard stainless steels such as 316/316L are not sufficient.

We supply high-quality 310MoLN round bar and 1.4466 stainless steel round bar for marine and offshore applications.
