Product Detail

Semi-austenitic precipitation-hardening stainless steel with added aluminum; the steel has similar component with 18-8 austenitic steel

Semi-austenitic precipitation-hardening stainless steel with added aluminum; the steel has similar component with 18-8 austenitic steel, good metallurgical property and processability; it can get different intensity, plasticity and toughness after heat treatment.

It is mainly used in making structural parts, container, pipeline, mechanical spring and gasket chronically working below 350℃.

The steel's technology of heat treatment is very complicated and it has the tendency to be replaced by maraging steel, but it is widely used at present.

Precipitation-Hardening Stainless Steel is chromium and nickel containing steel, which is a perfect combination of Martensitic Steel and Austenitic Steel grades. Precipitation-Hardening Stainless Steel Bar bears all the merits of Maraging Steel, such as high tensile strengths and inherits the advantage of Austenitic Stainless Steel, like corrosion resistance. They can be supplied in a "solution treated" condition, which is readily machineable.

The most well-known precipitation Precipitation-Hardening Stainless Steel isX5CrNiCuNb17-4, whose name comes from the additions 17% Chromium and 4% Nickel. It also contains 4% Copper and 0.3% Niobium. X5CrNiCuNb17-4 Precipitation-Hardening Stainless Steel is also known as type SUS630.

According to the final microstructures after heat treatment of Precipitation-Hardening Stainless Steel, they can be classified into three types, those are, martensitic, semi-austenitic and austenitic Precipitation-Hardening Stainless Steel.

The main different properties of Precipitation-Hardening Stainless Steel are as follows:

Yield strengths are 515 to 1415 MPa, and cold working before ageing can be used to facilitate even higher strengths.

Tensile strengths range from 860 to 1520 MPa.

Elongations are 1 to 25%.

Jinsong Stainless Steel manufacture the standard Precipitation-Hardening Stainless Steel with good combination of strength and corrosion resistance and other advantages. Our experts are ready to serve you and help you solve any problems anytime.
