The mechanical property of boiler tube is an important index to ensure the final service performance (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In steel pipe standards, tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness indexes, as well as high and low temperature properties required by users are specified according to different use requirements.
