1 Scope This standard specifies the steel dimensions, shape, weight and permissible tolerances, technical requirements, test methods, inspection rules, packaging, sign and quality certificate etc. of the hot rolling and hot forging structural steels subject to end-quench hardenability requirements. This standard is applicable to the hot rolling and forging structural steel bars of hardenability used in machinery manufacture with its diameter or thickness no less than 30 mm. The steel hardenability is determined by edge quenching or calculated by the formula. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to (excluding amending error in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of these documents is applicable. For undated references, the latest edition of the normative document is applicable to this standard.
