17 4 Stainless Steel Hardness

Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques.

17 4 stainless steel hardness.

Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. 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.

It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Grade 17 4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength. In addition it is more cost effective than many high nickel non ferrous alloys. Table 2 typical mechanical properties property.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. 17 chromium and 4 nickel. As sintered heat treated to h900 standard and heat treated to h1150 standard.

Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Stainless 17 4 ph 1 888 282 3292 upmet com type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels.

The numbers 17 4 refer to its composition. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. 17 4 stainless steel also known as sae type 630 is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress. In addition it is more cost effective than many high nickel non ferrous alloys. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel.
