Seamless Carbon Steel ASTM A53B High Pressure Boiler Tube ASTM A53
Boiler tube is a kind of seamless steel pipe and the same as the seamless steel pipe manufacturing method. But there are strict requirements for steel for boiler pipe manufacturing. According to the temperature rating, is divided into two kinds, low-pressure boiler tubes and high pressure boiler tubes.

Mechanical properties of boiler tubes is to ensure the final properties of the steel used (mechanical properties), which is an important indicator. And it depends on the chemical composition of the steel and the thermal processing system. In the steel standards, depending on the usage requirements, there are some formulations for of the tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness and high temperature performance metrics required by the user.
