Specifications of 17-4PH SUS630 1.4542 S17700 S17400 Precipitation-Hardening Stainless Steel plate

17-4PH SUS630 (1.4542/S17700/S17400) is a precipitation-hardening stainless steel plate known for balancing high strength, corrosion resistance, and durability. This material is widely used in demanding environments where mechanical performance and resistance to harsh conditions are critical. The steel plate is classified under martensitic precipitation-hardening stainless steels, offering versatility in applications ranging from aerospace to industrial machinery.

The chemical composition includes chromium (15-17.5%), nickel (3-5%), copper (3-5%), and small amounts of niobium/tantalum (0.15-0.45%). These elements enhance strength, toughness, and resistance to corrosion. Chromium provides a protective oxide layer, improving resistance to oxidation and acidic environments. Copper and niobium contribute to the hardening process during heat treatment.

Mechanical properties vary based on heat treatment conditions. In the solution-annealed state (Condition A), the plate has a tensile strength of approximately 1000-1100 MPa. After aging at 480-620°C (Condition H900), tensile strength increases to around 1310 MPa. Yield strength reaches up to 1170 MPa, with hardness levels of 40-45 HRC. The material maintains good ductility, with elongation values around 10-12% in treated conditions.

Heat treatment involves solution annealing followed by aging. Solution annealing is done at 1020-1060°C, followed by rapid cooling. Aging at specific temperatures (480-620°C) precipitates intermetallic phases, optimizing strength and hardness. The process allows customization of mechanical properties to meet application needs.

17-4PH stainless steel plates are used in aerospace components, turbine blades, chemical processing equipment, and medical instruments. They perform well in environments exposed to saltwater, acidic solutions, and high stress. The material’s weldability and machinability are better than many high-strength steels, though post-weld heat treatment is recommended to restore properties.

Advantages include high strength-to-weight ratio, resistance to stress corrosion cracking, and stability across temperatures from -40°C to 300°C. The steel is available in thicknesses from 0.5mm to 150mm, with surface finishes including hot-rolled, cold-rolled, and polished options. Compliance with standards like AMS 5643 and ASTM A693 ensures consistent quality.

Handling requires proper storage to prevent surface contamination. Cutting and machining should use tools designed for high-strength alloys to avoid work hardening. Regular inspection for surface defects is advised to maintain performance integrity.
