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.
