The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.
17 4 ph stainless steel hardness.
It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper.
Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly.
For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.
Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved.

The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.
Powerful equipments are required for forming this alloy because it is stronger than the regular steel.
It is also known as 630 stainless steel.
Markforged represent typical tested values.
17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c.
Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media.
As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.
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.
17 4 ph steel contains 4 copper and may be hardened by a single low temperature precipitation hardening heat treatment producing excellent mechanical properties at a high strength level.
17 4 ph mim standard stainless steel heat treated to h900 specification.
In addition it is more cost effective than many high nickel non ferrous alloys.
