Material 1.4439 is an austenitic chromium-nickel-molybdenum stainless steel. Its high molybdenum content, combined with added nitrogen, provides enhanced corrosion resistance, especially in environments with acid chlorides. This composition also improves protection against pitting and crevice corrosion.
The nitrogen in Alloy 317LMN increases its yield strength compared to 317L. Being a low-carbon grade, 317LMN can be welded without the risk of chromium carbide precipitation at grain boundaries, even in the as-welded condition.
Alloy 317LMN is non-magnetic when annealed and cannot be hardened by heat treatment, only through cold working. It is easy to weld and fabricate using standard processes.
You can purchase material 1.4439 at a competitive price from the Evek GmbH online shop, with high-quality round bars available for worldwide shipping.
