1, Different material properties
Cold rolled sheet and cold hardened sheet have different material properties. Cold rolled plates are usually made of ordinary carbon steel, low alloy steel, or stainless steel, and the manufacturing process involves hot rolling followed by cold rolling and annealing. Cold hardening plates are usually made of high-strength low alloy steel or stainless steel materials, and the manufacturing process is hot rolling, cold rolling to a certain processing hardness, and then quenching or bainitic transformation treatment.
2, Different processing performance
Due to differences in material properties, there are also differences in processing performance between cold-rolled sheets and cold hardened sheets. Due to the higher hardness and strength of cold hard boards, they are not easy to process. Cold rolled sheets are suitable for various forming processes, such as cutting, punching, bending, etc.
3, Applicable scope varies
The application range of cold-rolled sheet and cold hardened sheet is also different. Cold rolled sheet is suitable for manufacturing various industrial products such as mechanical parts, vehicles, ships, etc. It can also be used in construction decoration, electrical industry, etc. Cold hard boards are mainly used in fields such as building structures, road railings, and ship materials, and their high strength and wear resistance can greatly improve their service life.
4, Different usage environments
Cold rolled sheet and cold hardened sheet also have different usage environments. Due to the higher material strength of cold hard boards, they can also exhibit better performance in harsh environments. Cold hard boards also have better corrosion resistance, so it is more suitable to use them in situations where higher requirements for corrosion-resistant materials are needed.
In summary, although both cold-rolled sheet and cold hardened sheet belong to metal sheets, their material properties, processing performance, applicability, and usage environment are different. When selecting materials, appropriate materials should be selected based on specific needs.
