17 4 Stainless Steel Hardness

17 chromium and 4 nickel.

17 4 stainless steel hardness.

17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels.

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. The numbers 17 4 refer to its composition. It also can include between 3 and 5 copper.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. 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. In addition it is more cost effective than many high nickel non ferrous alloys.

It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. 17 4 stainless steel 17 4 uns s17400. Mechanical properties can be optimized with heat treatment.

As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress. 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. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. 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 name comes from the chemical makeup which is approximately 17 chromium and 4 nickel. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.

Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. Table 2 typical mechanical properties property. Grade 17 4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques.
