15-5PH Stainless Steel Cold-Rolled Sheets – Ideal for Aerospace & Industrial Applications

Product Overview

The 15-5PH Stainless Steel Cold-Rolled Sheet is a high-performance precipitation-hardening alloy known for its exceptional strength, toughness, and corrosion resistance. Engineered for critical applications, this stainless steel grade delivers consistent performance under demanding mechanical and environmental conditions. With its fine grain structure and superior mechanical properties, 15-5PH is widely used in aerospace, marine, chemical, and industrial machinery.

The cold-rolled process ensures a smooth surface finish, tight dimensional tolerances, and enhanced mechanical strength, making it ideal for precision components and structural applications.

Key Features

• High Strength and Hardness: Excellent mechanical properties after heat treatment.

• Superior Corrosion Resistance: Performs well in both oxidizing and mild acidic environments.

• Excellent Fabricability: Suitable for forming, machining, and welding operations.

• Aging Hardenable: Strength can be adjusted through heat treatment (H900–H1150 conditions).

• Precision Cold-Rolled Surface: Ensures smooth finish and accurate dimensions.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between 15-5PH and 17-4PH stainless steel?
A: 15-5PH has better toughness and a more refined microstructure than 17-4PH due to controlled melting and processing, providing improved transverse mechanical properties.

Q2: Can 15-5PH be welded or machined easily?
A: Yes. It has good machinability and weldability, especially when supplied in the solution-annealed condition.

Q3: What heat treatment is used to achieve maximum strength?
A: Aging at 900°F (482°C) – known as the H900 condition – provides the highest strength and hardness.

Q4: Is 15-5PH suitable for marine environments?
A: Yes. Its chromium, nickel, and copper content provide excellent resistance to marine and salt spray corrosion.

Q5: Do you offer customized sizes and finishes?
A: Absolutely. Sheets can be cut, polished, or finished according to customer requirements.
