QP The microstructure of steel is martensite, retained austenite and ferrite. During the forming process, the remained austenite can perform phase-transformation into martensite; and have higher work hardening rate, uniform elongation and tensile strength. Compared with the dual phase steel with the equivalent tensile strength, it has higher elongation; compared with the phase-transformation-induced plastic steel with equivalent tensile strength, it has lower carbon equivalent.4 Classification and Code4.1 The grade of steel sheet and strip consists of three parts, namely, initials “CR” of “Cold Rolled”, specified minimum yield strength value/specified minimum tensile strength value, and initials “QP” of “Quenching and Partitioning”. Example. CR550/980QP CR – initials of “Cold Rolled”; 550/980 – 550. specified minimum yield strength value, in MPa; 980. specified minimum tensile strength value, in MPa; QP – Initials of “Quenching and Partitioning”. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
