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.
