17 4 Ph Stainless Steel Heat Treatment

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 stainless steel heat treatment.

Secondary electron analysis of martensitic ph 17 4 stainless steel sem. 17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c. Heat at 1900ºf 1040ºc for 30 minutes and cool to below 90ºf 32ºc to allow complete. 17 4 ph stainless steel 2 as supplied from the mill in condition a 17 4 ph stainless steel can be heat treated at a variety of temperatures to develop a wide range of properties.

It is also known as 630 stainless steel. Eight standard heat treatments have been developed. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. Alloy 17 4 can be heat treated to a variety of temperatures to develop a wide range of properties.

Its mechanical properties can be optimized with heat treatment where very high yield strength up to 180 ksi can be achieved. Alloy 17 4 should not be used at temperatures above 572 f or at very low temperatures. Stainless steel al 17 4 alloy summary of heat treating al 17 4 alloy minimum properties specified in aerospace material specification ams 5604 heat treat to produce martensitic structure precipitation heat treatment to produce desired strength solution heat treatment at 1950 f 1066 c precipitation hardening heat treatment 900 f. Mechanical properties can be optimized with heat treatment.

Tem bright field image of the d ferrite phase in 17 4 ph stainless steel after solution treatment. Fine cu precipitates are observed. The following chart outlines the times and temperatures required. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved.

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.
