Precipitation-hardening martensitic steel (PH stainless steel) is a premium class of stainless steel engineered to deliver an outstanding combination of high strength, corrosion resistance, and reliability.

Grades

Through a controlled process of solution treatment and aging, fine precipitates are formed within a martensitic structure, resulting in exceptional mechanical performance with minimal distortion. This makes PH steels an ideal choice for precision-critical and high-performance applications.

Key advantages:

  • Exceptional strength and hardness
  • Superior corrosion resistance compared to conventional martensitic steels
  • Excellent toughness and reliability
  • Outstanding dimensional stability during heat treatment

We offer a comprehensive range of PH grades, including 17-4PH, 15-5PH, and 13-8, widely recognized for their performance in demanding industries such as aerospace, oil & gas, energy, and precision engineering. These materials are designed to meet the highest standards where performance, consistency, and durability are critical.
