17 4 Ph Stainless Steel Properties

Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques.

17 4 ph stainless steel properties.

17 4 stainless steel 17 4 uns s17400. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. This article will focus on two types in particular. In addition it is more cost effective than many high nickel non ferrous alloys.

17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. The numbers 17 4 refer to its composition.

Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. 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. 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. 17 chromium and 4 nickel. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper.

17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c. Mechanical properties can be optimized with heat treatment. 17 4 and 316l stainless steel. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels. High strength is maintained to ap proximately 600 f 316 c. Type 17 4 ph is a martensitic precipitation hardening stainless steel that. Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions.

Table 2 typical mechanical properties property. 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. 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.

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.
