17 4 Stainless Steel Hardness

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.

17 4 stainless steel hardness.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. 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.

Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques.

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. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. 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. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties.

In addition it is more cost effective than many high nickel non ferrous alloys. Mechanical properties can be optimized with heat treatment. Table 2 typical mechanical properties property. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels.

Grade 17 4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. In addition it is more cost effective than many high nickel non ferrous alloys. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.

The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel. The numbers 17 4 refer to its composition. 17 4 stainless steel 17 4 uns s17400. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel.
