13-8 stainless steel alloy is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance.
This alloy is double melted in a Vacuum Induction Furnace followed by Consumable Electrode Vacuum Melt (VIM-VAR); or in some cases, the second melt is by Electroslag Remelting (ESR) as specified by the consumer. It exhibits 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. 13-8 PH steel provides a wide range of properties through a single precipitation hardening heat treatment. It is weldable; inert gas shielding with Helium is preferred. Corrosion resistance is similar to 304 Stainless, with
greatest resistance in the fully hardened conditions.
Compared to other ferrous-base materials alloy 13-8 Stainless Steel offers a high level of useful mechanical properties under severe environmental conditions.
