X10CrNi18-8 - Nr.1.4310

High-Strength Chromium-Nickel Austenitic Stainless Steel

Chromium-nickel austenitic stainless steel. The rather high carbon content allows high values of mechanical resistance to be achieved through extrusion hardening. Used for springs, antennas, and high resistance pieces.
