Stainless Steel 431X (1.4057) Medical Alloy

Enhanced version of 431 produced by special powder metallurgy technology which produces a very fine microstructure and homogeneity, resulting in much reduced rejection rates for finished parts. High hardenability makes it ideal for gear and rotating parts (pliers, pincers, dental drills etc) as well as for the most demanding cutting instruments in the medical, surgical and dental industries.

Applications
