This black annealed steel strip coils good is high-temperature oxidation resistance. It is good corrosion resistance after quenching and polishing, and small deformation after heat treatment. It has a high-quality surface finish and gets well prepared for surface coating. The cold-rolled sheet strip coils have the advantages of smooth surface, smooth formation, high dimensional accuracy.
These cold-rolled sheet strip coils denote black without bright treatment, and their physical properties are soft. The surface of annealed steel coils is black, which is slightly cheaper than the bright ones. These cold-rolled steel sheet coils are production efficient, easy to use, good for subsequent processing. It features excellent mechanical properties such as yield strength and tensile strength, etc.
- Clean, smooth finish.
- Good welding performance.
- Good corrosion resistance, durable.
- High strength and high-temperature oxidation.
- Surface appearance and the use of the possibility of diversification.
Widely used in machinery manufacture and house applications.
