17 4 Stainless Steel Hardness

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.

17 4 stainless steel hardness.

In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels. The numbers 17 4 refer to its composition. 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.

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. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions.

Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques. In addition it is more cost effective than many high nickel non ferrous alloys. 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 17 4 uns s17400.

Table 2 typical mechanical properties property. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. 17 4 ph stainless steel mechanical properties ak steel 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.

It also can include between 3 and 5 copper. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media.

Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. 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.

17 chromium and 4 nickel. 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. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.
