Seamless Carbon Steel ASTM A106B High Pressure Boiler Tube ASTM A106
Boiler Tube is a kind of seamless steel pipe. The manufacturing method is the same
as seamless steel pipes. But there are strict requirements for the steel grades used to manufacture
boiler steel tubes. According to the temperature level, it is divided into two types: low pressure boiler
tube and high pressure boiler tube.

The mechanical properties of the boiler tube are important indicators to ensure the end-use
performance (mechanical properties) of the steel.
It depends on the chemical composition of the steel and the heat treatment system. In the steel
pipe standard, according to different use requirements, the tensile properties (tensile strength,
yield strength or yield point, elongation), hardness and toughness indicators, as well as the high
and low temperature properties required by users are specified.
