7111 Quality Sheet Specification
General application steels for drawing (automotive, refrigerators, washing machines, home appliances, etc)
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.

- Tensile test values apply to "transverse" test pieces
- For design purposes, the lower limit of Re may be assumed to be 140 N/mm² (14,3 kg/mm²)
- The upper limit Re of 280 Mpa is valid only for 8 days from the time of the availability of the product and recomended that the products should be formed within 6 weeks from the time of their availability.
- The guarantee period of absence of stretcher strains marks is 3 months for B surface quality products.
