17 4 ph stainless steel properties.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. 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. 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. The name comes from the chemical makeup which is approximately 17 chromium and 4 nickel.

Powerful equipments are required for forming this alloy because it is stronger than the regular steel. Also known as uns 17400 is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15 17 5 chromium and 3 5 nickel as well as 3 5 copper. The numbers 17 4 refer to its composition.

17 4 and 316l stainless steel. In addition it is more cost effective than many high nickel non ferrous alloys. Type 17 4 ph is a martensitic precipitation hardening stainless steel that. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.

The grade combines high strength hardness up to 572 f 300 c and corrosion resistance. Grade 17 4 stainless steel has high ductility and can be formed using all conventional techniques. 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 stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties.

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. 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. 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. Mechanical properties can be optimized with heat treatment. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. 17 4 stainless steel 17 4 uns s17400.

Sae type 630 stainless steel more commonly known as 17 4 ph or simply 17 4. Type 17 4 ph stainless steel is the most widely used of all of the precipitation hardening stainless steels. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. 17 chromium and 4 nickel.

High strength is maintained to ap proximately 600 f 316 c.
