JIS G3461 STB510 Carbon Steel Boiler Pipe
JIS G3461 STB510 boiler and heat exchanger tubes are designed for high temperature, high pressure and corrosive environments and are suitable for a wide range of industrial applications. It can provide stable heat transfer and excellent pressure-bearing capabilities required by thermal equipment such as boilers and heat exchangers, thereby ensuring the smooth operation and safety performance of these equipment.
The reason why STB510 high temperature resistant steel pipe exhibits excellent strength and hardness in high temperature environments is mainly due to its high carbon content. This allows the steel pipe to withstand extreme operating pressures, demonstrating exceptional durability. Its minimum tensile strength reaches 510 MPa, and its minimum yield strength is as high as 295 MPa, confirming its applicability in application scenarios such as high-pressure boilers.
