China Super Lowest Price Cold Rolled Steel Angle - CRC Manufacture Black Annealed Cold Rolled Steel Coil With SPCC DX51D Q195 Q235 - Ruiyi Manufacturer and Supplier | Ruiyi

CRCA is an abbreviation of “cold rolled close anneal”. This is a steel grade in which cold rolling is done after hot rolling and pickling, to reduce the thickness of steel. Cold rolling makes the material hard

Annealing cold rolled steel involves a time and temperature controlled thermostatically process used predominantly to make steel soft again after cold reduction. Cold reduction or work hardening makes steel grain structure small and elongated. This produces high strength, but low elongation

The main advantages of annealing are in how the process improves the workability of a material, increasing toughness, reducing hardness and increasing the ductility and machinability of a metal
