Precipitation hardening stainless steel are designed to be formable in the solution annealed condition and can subsequently be hardened by heat treating to strength levels several times that of Type 304. Precipitation hardening stainless steel may be martensitic or semi-austenitic (sometimes called metastable austenitic) and contain chromium and nickel as the major alloying elements. Corrosion resistance is usually better than that of straight chromium ferritic.

Precipitation hardening Stainless Steel is developed by adding different types and numbers of reinforcing elements on the basis of the chemical composition of stainless steel through the precipitation process and the number of different types of carbides, nitrides, carbonitrides and intermetallic compounds. It is a class of high strength stainless which has improved strength of steel and sufficient toughness.

Features:

1.Excellent strength at room temperature
2.Good resistance to general corrosion, oxidation, sulfide and fatigability.
3.High strength with high toughness, good toughness at low temperature
4.Good cold/hot workability and weldability
