13-8 MO Solution Treated - Stainless Steel - Fry Steel

Stainless Steel / 13-8 MO SOL TR

PH 13-8 Mo Type 1 VIM / VAR aircraft-quality stainless is a martensitic precipitation/age-hardening stainless steel capable of high strength and hardness along with good levels of resistance to both general corrosion and stress-corrosion cracking. In addition, the alloy exhibits good ductility and toughness in large sections in both the longitudinal and transverse directions. The excellent properties of PH 13-8 Mo stainless are obtained through close control of chemical composition and microstructure plus specialized melting which reduces impurities and minimizes segregation. Compared to other ferrous-based materials, this alloy offers a high level of useful mechanical properties under severe environmental conditions. (UNS:S13800)
