GB/T 20564 consists of the following eleven parts under the general title Continuously cold rolled high strength steel sheet and strip for automobile: ——Part 1: Bake hardening steel; ——Part 2: Dual phase steel; ——Part 3: High strength interstitial free steel; ——Part 4: High strength low alloy steel; ——Part 5: Isotropic steel; ——Part 6: Transformation induced plasticity steel; ——Part 7: Martensitic steels; ——Part 8: Complex phase steel; ——Part 9: Quenching and partitioning steel; ——Part 10: Twinning induced plasticity steel; ——Part 11: Carbon manganese steel. This part is Part 10 of GB/T 20564. This part is developed in accordance with the rules given in GB/T 1.1-2009. This part was proposed by China Iron and Steel Association. This standard is under the jurisdiction of the SAC/TC 183 National Technical Committee on Iron and Steel of Standardization Administration of China. Continuously cold rolled high strength steel sheet and strip for automobile — Part 10: Twinning induced plasticity steel 1 Scope This part of GB/T 20564 specifies the term and definition, classification and designation representation methods, order information, dimension, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificate for cold rolled twinning induced plasticity high strength steel sheets and strips. This part is applicable to the 0.50 mm to 3.00 mm-thick steel sheets and strips for manufacturing automobile complex-shape structural member and reinforcing member with a thickness of 0.50 mm~3.00 mm (hereinafter referred to as "steel sheets and strips"). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
