Common Trade Names: 13-8Mo, PH13-8Mo, S51380, 04Cr13Ni8Mo2Al, xm-13,UNS S13800,Werkstoff 1.4548

PH13-8Mo stainless is a martensitic precipitation hardening stainless steel that has excellent strength, high hardness, superior toughness and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. Typical applications are large airframe structural components and injection molding equipment.
