231 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 upper limit Re of 280 Mpa is valid only for 8 days from the time of the availability of the product and recommended that formed within 6 weeks from the time of their availability.
