17 4 Stainless Steel Hardness

The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

17 4 stainless steel hardness. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels. 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. Mechanical properties can be optimized with heat treatment. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties.

Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. 17 chromium and 4 nickel.

Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. As sintered heat treated to h900 standard and heat treated to h1150 standard. 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. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.

It also can include between 3 and 5 copper. Table 2 typical mechanical properties property. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.
