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.
