17 4 Ph Stainless Steel Properties

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.

17 4 ph stainless steel properties.

The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. 17 4 and 316l stainless steel.

17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. The numbers 17 4 refer to its composition. 17 4 stainless steel 17 4 uns s17400. 17 4 ph provides this high strength in combination with good mechanical properties at temperatures of up to 600 f 316 c.

Table 2 typical mechanical properties property. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. This article will focus on two types in particular. High strength is maintained to ap proximately 600 f 316 c.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. Grade 17 4 stainless steel is annealed at 1038 c 1900 f for 0 5 h followed by cooling rapidly. 17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

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 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 chromium and 4 nickel. 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.

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. Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques.

Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels. Mechanical properties can be optimized with heat treatment. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. Type 17 4 ph is a martensitic precipitation hardening stainless steel that.

In addition it is more cost effective than many high nickel non ferrous alloys.
