Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel.
17 4 ph stainless steel properties pdf.
Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.
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.
Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs.
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.
General properties allegheny ludlum s al 17 4 precipitation hardening alloy s17400 type 630 is a chromium nickel copper precipitation hardening stainless steel used for applica tions requiring high strength and a moderate level of corrosion resistance.
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.
For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.
As with other precipitation hardening stainless steels ati 17 4 precipitation hardening stainless steel is more susceptible to stress corrosion cracking at peak strength.
The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.
304 stainless steel in most media.
This alloy is typically furnished in condition a annealed but can be cold rolled to various temper.
