Stainless Steel 15-5 PH Round Bar

Grade Introduction

Stainless Steel 15-5 PH is a precipitation-hardening martensitic stainless steel known for its high strength, good corrosion resistance, and ease of machining. It combines excellent mechanical properties with moderate corrosion resistance, making it suitable for demanding applications.

Grade Application:

  • Aerospace components
  • Automotive parts
  • Industrial machinery
  • Valves
  • Pump components

Thermal Properties:

Properties Value
Maximum Operating Temperature (°C/°F) 300°C (572°F)
Thermal Conductivity (W/m-K) 15.4
Specific Heat (J/kg-K) 500

Forging Properties:

Forge Stainless Steel 15-5 PH within a temperature range of 1050-1150°C (1922-2102°F). The typical reduction ratio is around 4:1. Post-forging heat treatment is essential to relieve stresses and achieve the desired hardness and mechanical properties.

Stress Relieving:

To stress relieve Stainless Steel 15-5 PH, heat it to a temperature range of 620-760°C (1148-1400°F) for 1-2 hours. Slow cooling is recommended to stabilize the material and minimize the introduction of new stresses.
