234 Quality Sheet Specification
Low carbon steels for cold forming
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.

- The transverse and longitudinal test values are the same. Then tensile test is performed only transverse and shown on the certificate. It is also guaranteed longitudinal test values.
- The values of r90 only apply to products of thickness d ≥ 0.5 mm.
- Average Plastic Strain Ratio (ravg) is calculated as a weighted average of the individual r-values, i.e., ( r0+r90+2r45) / 4
