17 4 Ph Stainless Steel Properties

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 ph stainless steel properties.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Mechanical properties can be optimized with heat treatment. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. 17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c.

In addition it is more cost effective than many high nickel non ferrous alloys. High strength is maintained to ap proximately 600 f 316 c. Powerful equipments are required for forming this alloy because it is stronger than the regular steel. This article will focus on two types in particular.

Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. In addition it is more cost effective than many high nickel non ferrous alloys. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly.

The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel. 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. Table 2 typical mechanical properties property.

The numbers 17 4 refer to its composition. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. 17 4 stainless steel 17 4 uns s17400. 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 ph steel contains 4 copper and may be hardened by a single low temperature precipitation hardening heat treatment producing excellent mechanical properties at a high strength level. Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. Type 17 4 ph is a martensitic precipitation hardening stainless steel that.

17 chromium and 4 nickel. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs.

Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved.
