CP-K 570Y780T is one of a family of complex-phase steels, CP-W and CP-K, that offer very high strengths and yield points. They are particularly suitable for weight-saving production of cold-formed, crash-relevant automotive components such as side impact intrusion beams, B-pillar reinforcements,profiles, cross members, body reinforcements, bumper bars, and chassis parts. This datasheet provides information on composition, hardness, and tensile properties. It also includes information on heat treating. Filing Code: SA-848.
