Precipitation hardening (PH) stainless steels are chromium and nickel containing steels that provide an optimum combination of the properties of martensitic and austenitic grades.
Like martensitic grades, they are known for their ability to gain high strength through heat treatment and they also have the corrosion resistance of austenitic stainless steels.
The high tensile strengths of precipitation hardening stainless steels come after a heat treatment process that leads to precipitation hardening of a martensitic or austenitic matrix. Hardening is achieved through the addition of one or more of the elements Copper, Aluminum, Titanium, Niobium, and Molybdenum.
Delta Alloys can satisfy the most demanding requirements in: PH13-8MO, 15-5PH, 17-4PH, 17-7PH, 15-7PH in the form of plate, sheet, bar as well as forged block.
