17 4 Ph Stainless Steel Properties

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

17 4 ph stainless steel properties. 17 chromium and 4 nickel. 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. In addition it is more cost effective than many high nickel non ferrous alloys.

Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Mechanical properties can be optimized with heat treatment. Powerful equipments are required for forming this alloy because it is stronger than the regular steel.

17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. Table 2 typical mechanical properties property. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. High strength is maintained to ap proximately 600 f 316 c. 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. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. 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. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques. 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. General properties allegheny ludlum s al 17 4 precipitation hardening alloy s17400 type 630 is a chromium nickel copper precipitation hardening stainless steel used for applica tions requiring high strength and a moderate level of corrosion resistance. In addition it is more cost effective than many high nickel non ferrous alloys. 17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c.

This article will focus on two types in particular. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. Type 17 4 ph is a martensitic precipitation hardening stainless steel that.

Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels.
