Stainless steel 13-8 PH is a martensitic, precipitation-hardening alloy known for its high strength, hardness, and excellent resistance to general and stress corrosion cracking. It offers good ductility and toughness even in larger cross-sections, both longitudinally and transversely. These outstanding mechanical properties are achieved through strict control of chemical composition, microstructure, and a specialized melting process that minimizes impurities and segregation. Compared to other steel alloys, 13-8 PH performs exceptionally well under challenging environmental conditions.
This stainless steel grade is easy to process and can be hardened in a single, low-temperature step. Cold working before hardening can speed up the process, especially at lower temperatures.
