17-4 stainless is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel.
What kind of material is 17-4?
stainless steel
How hard is 17-4 PH stainless steel?
Properties. 17-4 can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless. 17-4 is capable of being hardened up to approximately 44 Rc when heat treated to condition H900.
What is the difference between 17-4 and 316 stainless steel?
SS316 and 17-4 PH are common used two types of stainless steel grades for investment casting. 316 is typical austenite stainless steel casting grade, while 17-4 PH stainless steel is precipitation hardening material grade, which are all defined in American standards.
What is the hardness of 17-4 stainless steel?

Does 17-4 PH harden?
Alloy 17-4PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F /300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment.
Will 17-4 PH rust?
The martensitic PH stainless grades like 17-4 and 15-5 will also rust. Note that Alloy 36 (36% NI, balance iron) will readily rust. It is not a stainless steel, since it has no chromium. These alloys are commonly delivered from the mill with a light rust or dark oxide on the surface.
What is the hardness of 17-4 Condition A?
What type of stainless steel is 17-4 PH?
hardening martensitic stainless steel
What type of material is 17-4 PH?
Stainless Steel
What is the difference between H1150 and HH1150?
HH1150 Condition A material heated 4 hours at 1150°F, air cooled, heated again for an additional 4 hours at 1150°F and air cooled. H1150-M Condition A material heated at 1400°F + 25°F for 2 hours, air cooled, then heated at 1150°F + 15°F for 4 hours and air cooled.
What is 17-4 PH used for?
17-4 PH Stainless Steel is a precipitation hardening martensitic stainless steel. Typical usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.
