UNS S17400 Stainless Steel Bolts – Product Overview
17-4 PH Stainless Steel Bolts are manufactured from a chromium-nickel-copper precipitation-hardening stainless steel grade designed to provide an excellent balance of strength, hardness, toughness, and corrosion resistance. The material is widely recognized for its ability to achieve significantly higher mechanical properties than conventional austenitic stainless steel grades such as 304 and 316.
The precipitation hardening process enables the alloy to develop outstanding tensile and yield strength while maintaining good resistance to atmospheric corrosion, freshwater environments, and many industrial chemicals. These characteristics make UNS S17400 Stainless Steel Bolts suitable for highly stressed applications where structural integrity is critical.
In addition to superior mechanical performance, 17-4 PH Stainless Steel offers good machinability, weldability, and fabrication characteristics. Industries such as aerospace, defense, marine engineering, petrochemical processing, and power generation rely on these bolts for applications where strength, reliability, and service life are essential factors.
Common applications include turbine assemblies, aircraft structures, pump shafts, valves, offshore equipment, pressure systems, industrial machinery, defense hardware, and precision engineering components.
