ASTM A313/A313M Stainless Steel Spring Wire 17-7PH SUS631J1
Stainless steel precipitation hardening wire, also known as PH stainless steel wire,
a type of stainless steel wire that undergoes a process precipitation hardening to achieve improved strength and hardness.
The most common type of stainless steel used for precipitation hardening wire is known as PH 17-4 stainless steel,
which belongs to the 17-4 PH stainless steel family.
It contains approximately 17% chromium and 4% nickel, along with other alloy elements such as copper and niobium.
The addition of these elements helps to promote the precipitation of fine particles during the heat treatment process.
Stainless steel precipitation hardening wire is commonly used in applications that require high strength, corrosion
resistance and good mechanical properties. It finds applications in industries such as aerospace, oil & gas,
automotive and medical. Some common uses of precipitation hardening wire include springs, fasteners, shafts,
valves and components for high-stress environments.
17-7PH Stainless Steel is a precipitation hardening stainless steel that provides excellent fatigue properties,
good corrosion resistance and minimum distortion on heat treatment.
Hard-drawn 17-7 PH wire is an excellent spring material.
When heat treated at 482°C , it exhibits elastic properties like those of the best music wire and alloy spring steels.
Solution heat treated (annealed) 17-7 PH wire can be readily cold formed before heat treating to high
tensile strengths and high hardness.
At service temperatures up to about 316°C (600°F), 17-7PH Stainless Steel has higher
strength than nickel-chromium, nickel-copper, nickel-aluminum and copper-beryllium alloys.
