The mechanical properties of the boiler tube are important
indicators to ensure the end-us
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.
