131 Quality Sheet Specification
Non-aging extra deep-drawing quality steels (Ultra low carbon IF steels)
Reproducible Letter Symbols --> CCR --> CCRD --> CCR
AlternativesThere is no alternative to this sheet.
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.
