Type 17 4 ph is a martensitic precipitation hardening stainless steel that.
17 4 provides an outstanding combination of high strength good mechanical properties at temperatures up to 600 f 316 c and short duration low temperature heat treatments that minimize warpage and scaling.
Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4.
The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.
Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs.
In addition it is more cost effective than many high nickel non ferrous alloys.
