7.80g/cm3 Precipitation Hardened Stainless Steel 630 For Oil / Gas Industry

17-4PH stainless steel offers excellent corrosion resistance, mechanical properties, and heat treatment plasticity, with exceptional chloride stress corrosion cracking resistance in chloride environments. Its composition includes iron, chromium, nickel, copper, and molybdenum, with small amounts of carbon and niobium, providing good mechanical properties and corrosion resistance, especially in high-temperature and strongly corrosive environments.

• High strength: Can reach tensile strength of about 1100 MPa under H1150 condition (solution treatment plus low temperature aging).
• Good corrosion resistance: Superior performance in various climates and chemical environments.
• Excellent heat treatment performance: Properties can be adjusted through heat treatment for different applications.
• Good grinding performance: Suitable for applications requiring high precision and surface quality.
• Weldability: Performs well under proper welding methods and heat treatment.

• Aerospace: Aircraft parts, engine components, structural elements
• Oil and gas industry: Valves, pump components, pipe connections
• Medical devices: Surgical instruments, orthopedic implants
• Marine engineering: Offshore platforms, marine equipment
• Automobile industry: Engine and transmission components
• Military industry: Weapon systems, missile components

17-4PH stainless steel is widely used in high-demand engineering and manufacturing fields requiring high strength, excellent corrosion resistance, and good heat treatment performance.
