Product Description
1.4542 17-4PH S17400 Stainless Steel Coil is a high-performance precipitation hardening stainless steel designed for applications requiring high mechanical strength, excellent corrosion resistance, and dimensional stability.
Also identified as X5CrNiCuNb16-4 according to DIN standards, AISI 17-4PH and UNS S17400, this stainless steel combines the advantages of martensitic stainless steel and age-hardening technology.
Key Features:
- Extremely high strength after aging treatment
- Excellent resistance to stress corrosion cracking
- Good weldability and machinability
- Stable performance under heavy loads
- Good oxidation resistance at elevated temperatures
- Suitable for precision mechanical components
17-4PH precipitation hardening stainless steel provides specialized solutions for demanding applications where traditional stainless steel grades face limitations.
High Strength Structure:
17-4PH obtains superior mechanical properties through copper-rich precipitation during aging treatment, achieving very high strength without sacrificing corrosion resistance.
Corrosion Resistant Alloy Design:
Balanced alloy composition including Chromium for corrosion protection, Nickel for toughness, Copper for precipitation strengthening, and Niobium for structural stability.
Aerospace Component Solution:
Widely selected for aerospace parts requiring high reliability with advantages including high strength-to-weight ratio, excellent fatigue resistance, and good dimensional stability.
