7136 Quality Sheet Specification
High strength steels for cold forming
Reproducible Letter Symbols --> CCR --> CCRD --> CCRF --> CCRFS --> CCR
Flat / Cold Rolled
Cold rolled coils or flat steel products are produced by rolling hot rolled flat steels without a heat treatment operation in a thickness range of 0.20 to 2.00mm. While the product’s physical properties are all homogeneous along the strip, surface flatness, width and thickness values have fulfilled expectations at the top level.
