Precipitation Hardening Steel
What is precipitation hardening steel?
Precipitation Hardening (PH) steels are a specialized class of stainless and alloy steels designed to achieve high strength, excellent toughness, and superior corrosion resistance through heat treatment. These steels undergo a unique aging process in which fine precipitates form within the metal matrix, significantly enhancing mechanical properties while maintaining good ductility.
PH steels strike a balance between high-strength structural materials and corrosion-resistant alloys, making them ideal for demanding applications. They are widely used in aerospace, defense, power generation, and medical industries, where lightweight, high-strength materials with excellent fatigue resistance are required.
Key Properties
and Advantages
1. High Strength & Hardness
Precipitation hardening steels offer exceptional strength and hardness compared to conventional stainless and alloy steels. Their ability to undergo controlled heat treatment allows for precise tuning of mechanical properties, making them a preferred choice in high-performance applications.
2. Excellent Corrosion Resistance
Unlike many high-strength steels that are prone to corrosion, PH steels provide excellent resistance to oxidation and corrosive environments. This makes them suitable for marine, aerospace, and chemical processing applications where exposure to moisture, chemicals, or extreme temperatures is a concern.
3. Heat TREATABILITY & Stability
A defining feature of precipitation hardening steels is their ability to be hardened through a relatively low-temperature aging process. This allows manufacturers to produce complex components with ease and then strengthen them through heat treatment, reducing distortion and enhancing dimensional stability.
4. High Fatigue & Wear Resistance
PH steels are engineered to withstand cyclic loading, making them ideal for applications requiring long-term durability. Their superior wear resistance ensures extended service life in demanding environments such as aerospace landing gear, turbine blades, and high-stress structural components.
Materials We Offer
17-4 PH (UNS S17400)
One of the most widely used PH stainless steels, 17-4 PH offers a combination of high strength, excellent corrosion resistance, and good machinability. Commonly used in aerospace, medical instruments, and offshore applications, it delivers reliable performance in harsh environments.
15-5 PH (UNS S15500)
Similar to 17-4 PH but with improved toughness and better transverse properties, 15-5 PH is commonly used in structural aerospace components, pressure vessels, and high-performance industrial equipment.
13-8 MO (UNS S13800)
Known for its high strength, superior toughness, and excellent corrosion resistance, 13-8 MO is frequently used in aerospace, nuclear, and high-performance mechanical applications where extreme reliability is essential.
PH 13-8 (UNS S13800)
This precipitation-hardened stainless steel provides excellent resistance to stress corrosion cracking and maintains high strength at elevated temperatures, making it suitable for demanding aerospace and military applications.
A286 (UNS S66286)
A precipitation-hardened superalloy with outstanding high-temperature strength and oxidation resistance, A286 is used in jet engines, industrial gas turbines, and high-performance fasteners.
