17-4 PH Stainless Steel Casting

JC Casting is a 17-4 PH Stainless Steel Casting manufacturer in China. These years, we manufactured many castings parts with 17-4 stainless steel. Such as Medical surgical forceps, sponge clamp, hemostatic forceps. Footpeg in motorcycle industry. And big impellers in Shipbuilding or fluid industry.

All of these applications are from 17-4 PH Stainless Steel Casting features:

What is 17 4 PH stainless steel?

Its name is from its chemical composition which is about 17% chromium and 4% nickel. Alloy 17-4PH stainless steel (UNS S17400, Type 630 ), is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. It is the most used stainless steel alloy of all precipitation hardening stainless steel casting.

17-4 stainless steel casting typical application is for high strength and corrosion resistance required. The desired strength and toughness can be controlled in the heat treatment process.
