17 4 ph stainless steel properties pdf.

17 4 ph stainless steel 1 17 4 ph stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength good corrosion resistance good mechanical properties at temperatures up to 600 f 316 c good toughness in both base. Type 17 4 ph is a martensitic precipitation hardening stainless steel that. As with other precipitation hardening stainless steels ati 17 4 precipitation hardening stainless steel is more susceptible to stress corrosion cracking at peak strength. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4.

Mim h900 heat treated 17 4 ph mim standard stainless steel heat treated to h900 specification. In general the corrosion resistance of ati 17 4 alloy is superior to that of the hardenable 400 series stainless steels. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel.

This alloy is typically furnished in condition a annealed but can be cold rolled to various temper. 17 4 ph is a martensitic chromium nickel copper precipitation hardening stainless steel that provides an outstanding combination of high strength good corrosion resistance good mechanical properties at temperatures up to 600ºf 316ºc. 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. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Astm a564 17 4 ph stainless steel heat treated to h900 specification. It is also known as 630 stainless steel.

High strength 17 4 ph stainless steel with a higher chromium content than 15 5 ph stainless steel this high strength 17 4 ph offers better corrosion resistance. 304 stainless steel in most media. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. 17 4 stainless steel 17 4 uns s17400.

In addition it is more cost effective than many high nickel non ferrous alloys. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.
