Product Description

Product Description

Introduction

Stainless steel 15 - 5 PH, also known as XM-12 or UNS S15500, is a modification of 17-4 PH developed in the 1960s. It has a more refined microstructure obtained through the remelting process. This refined structure improves toughness of the material. UNS S15500 also has low temperature hardening, good fabrication properties and excellent corrosion resistance, which makes it suitable for many industries. It can be machined in the solution-annealed state or in final heat treat condition. The strength and ductility of UNS S15500 can be enhanced through heating the material at different temperatures.

UNS S15500 is a martensitic precipitation hardening type stainless steel. Martensitic stainless steels were designed to be corrosion resistant and hardened through heat treatment.

15-5 PH stainless steel is a martensitic precipitation-hardening stainless steel with approximately 15% Chromium and 5% Nickel. It has high strength, high hardness, and excellent corrosion resistance. Strength can be further increased by a single low temperature heat treatment. Compared to 17-4 PH, it offers better transverse toughness and ductility; better mechanical properties in larger cross-sections, and better forgeability. It is readily weldable. It can be machined in any of the several Thermal Conditions available to this grade.

Processing method

UNS S15500 can be machined under any of the attainable conditions. Firstly, the alloy is mildly formed in the overaged condition. It is then welded using welding techniques such as shielded fusion or resistance methods. The material is heat treated at 1038°C (1900°F) for 1/2 h, and then air cooled. This process is followed by hot-working the material and annealing at 1038°C (1900°F) for 1 h. Finally, the alloy can be cold-worked to improve its yield strength.

Applications

The following are some of the major applications of Grade 15-5 PH stainless steel:

• Marine gas turbine compressor sections
• Hallow shafts
• Paper mill equipment
• Engine parts
• Aircraft components
• Gears
• Fittings and fasteners
