PH13-8 Mo, X3CrNiMoAl13-8-2, 1.4534, UNS S13800 - Introduction and Application

PH13-8 Mo, X3CrNiMoAl13-8-2, 1.4534, UNS S13800 is a precipitation hardened martensitic stainless steel alloy, 13-8Mo steel has much more limited acceptability of sulfur and phosphorus in its chemical composition, which demonstrates a relatively difficult manufacturing process and high purity and quality of steel, so melted as VIM+VAR. This alloy offers good corrosion resistance and excellent strength excellent mechanical properties, high hardness, strength and relatively high corrosion resistance. The addition of Molybdenum allows improved pitting resistance as compared to other precipitation hardened grades such as 15-5 and 17-4.  Chromium-nickel-molybdenum stainless construction steel with aluminum additive ,  mainly used in the aerospace, nuclear, and petrochemical industries for parts and components subject to corrosion and Pins, Valves, Shafts, Screws and bolts, Missile components, Fittings and fasteners, Injection molding equipment, Nuclear and petrochemical industry equipment, Aircraft components such as engine, landing gear and structural sections.
