Cold-Rolled/Hot Rolled 15-5PH Stainless Steel Sheet Plate With Excellent Heat Treatment & Toughness

Cold-Rolled / Hot-Rolled 15-5PH Stainless Steel Sheet Plate With Excellent Heat Treatment & Toughness

Product Overview

15-5PH (UNS S15500) stainless steel is a precipitation-hardening martensitic stainless steel offering high strength, hardness, and corrosion resistance. It maintains excellent mechanical properties up to 600°F (315°C) and shows superior transverse toughness compared to 17-4PH due to its refined microstructure.

Both cold-rolled and hot-rolled 15-5PH stainless steel sheets and plates are widely used in aerospace, chemical, and mechanical applications requiring high strength and toughness.

FAQ

Q1: What’s the difference between 15-5PH and 17-4PH?
A: 15-5PH offers improved transverse toughness and more uniform properties due to its finer grain structure, while maintaining similar strength and corrosion resistance.

Q2: Can 15-5PH be welded?
A: Yes. It can be welded by standard methods such as TIG, MIG, or resistance welding, typically in the solution-treated condition.

Q3: What heat treatment conditions are available?
A: Supplied in solution-annealed (Condition A) or various aged conditions (H900, H1025, H1075, etc.).

Q4: Do you provide test certificates?
A: Yes, we provide Mill Test Certificates (MTC) as per EN 10204 3.1 / 3.2.

Q5: Can sizes be customized?
A: Yes, custom thickness, width, and length are available upon request.
