1. Cold rolled coils (annealed state): are obtained by bell annealing before rolling. After annealing, the work hardening
phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced by nearly before cold rolling.
2. Since there is no heating during the production process, there are no defects such as pitting and oxide scale that
often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of
cold-rolled products is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic properties, deep drawing properties, etc.
3. Specifications: thickness is 0.2-4mm, width is 600-2 000mm, and steel plate length is 1 200-6 000mm.
4. Brand: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06
erformance: Mainly using low carbon steel grades, which require good cold bending and welding properties, as well as certain stamping properties.
