JIS G3455 STS 410 seamless carbon steel pipes

JIS G3455 STS 410 seamless carbon steel pipes are used for high pressure service at an approximate maximum temperature of 350℃.

JIS G3455 STS 410 seamless carbon steel pipes

JIS G3455 STS 410 is a grade of carbon steel pipes specified under the Japanese Industrial Standard (JIS) G3455. The standard covers carbon steel pipes for high-pressure service at an approximate maximum temperature of 350°C.

STS 410 is a medium strength grade compared to STS 480 and STS 510. The mechanical properties of STS 410 carbon steel pipes can be varied through heat treating. By controlling the heating and cooling cycle, the desired properties are obtained by producing predictable changes in the microstructure of the steel.

These carbon steel pipes are commonly used in industrial applications where high-pressure and high-temperature conditions are present, such as steam boilers, pipelines, and high-pressure equipment. The minimum tensile strength of STS 410 is 412 MPa and the minimum yield strength is 245 MPa.

In summary, JIS G3455 STS 410 is a medium strength grade of carbon steel pipes used for high-pressure service at high temperatures. The mechanical properties of STS 410 can be varied through heat treating, making it suitable for a variety of industrial applications where harsh conditions exist.

These carbon steel pipes are designed to withstand high-pressure and high-temperature conditions, making them suitable for use in applications such as steam boilers, pipelines, and high-pressure equipment. The pipes are manufactured through a seamless process or a welded process, depending on the requirements of the application.

The mechanical properties of JIS G3455 carbon steel pipes vary depending on the grade. For example, STS 370 has a minimum tensile strength of 370 MPa and a minimum yield strength of 215 MPa, while STS 510 has a minimum tensile strength of 510 MPa and a minimum yield strength of 335 MPa.
