B GRADE BLACK ANNEALED
The high-quality hot-rolled coil material is used as raw material, and the cold-rolled sheet is made by cold rolling tandem rolling, electric washing, annealing, surface finishing, pickling and multi-step deformation. Cold rolled products have excellent mechanical precision, processing characteristics and thickness, and are suitable for use in construction vehicles, home appliances, transportation and other industries.
B GRADE BLACK ANNEALED is the second level product, the quality a little lower than A Grade, the price much lower than first class product.

This steel has been cold rolled. This steel adopts hot-rolled steel coil as raw material, and is subjected to pickling to remove scale and then cold-rolled. The final product is rolled hard roll, and the cold work hardening caused by sustaining cold deformation improves the strength and hardness of the rolled hard roll. Hence, the hardness of this product is very high.
This product has been annealed. After annealing, the metal loses its original hardness due to heat. Annealing reduces the hardness and brittleness of the metal and increases the plasticity of the product. In addition, it also makes the product easier to process.
