17 4 Stainless Steel Hardness

The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.

17 4 stainless steel hardness.

Mechanical properties can be optimized with heat treatment. The numbers 17 4 refer to its composition. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress. 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.

17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels. 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. 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.

Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. Grade 17 4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. In addition it is more cost effective than many high nickel non ferrous alloys.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. In addition it is more cost effective than many high nickel non ferrous alloys. 17 4 stainless steel 17 4 uns s17400. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly.

Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.
