Cold Rolled<\/a> Steel is a high-precision steel made from hot-rolled steel coils through room temperature rolling, annealing and other processes.<\/p>\n\n\n\n

Its core advantages:<\/h3><\/div>\n\n\n\n

Surface quality: smooth and scale-free (Ra\u22641.6\u03bcm), can be directly used for precision manufacturing.<\/p>\n\n\n\n

Mechanical properties: yield strength increased by 20%-50% (such as SPCC cold-rolled plate can reach \u2265280MPa), and deep drawing performance is excellent (elongation 30%-45%).<\/p>\n\n\n\n

Dimensional accuracy: thickness tolerance \u00b10.03mm, suitable for high-precision scenarios such as automotive panels.<\/p>\n\n\n\n

Processing adaptability: supports surface treatment such as electrogalvanizing and spraying to meet diverse corrosion resistance needs.<\/p>\n\n\n\n

International standard comparison<\/h3><\/div>\n\n\n\n

Chinese GB standards: DC01 (yield strength \u2264 280MPa), DC04 (yield strength \u2264 210MPa), DC07 (yield strength \u2264 150MPa)<\/p>\n\n\n\n

American standard ASTM: CS\/DS\/DDS\/EDDS series (such as CS grade yield strength of 140-275MPa)<\/p>\n\n\n\n

Application Fields and Common Cases<\/h2><\/div>\n\n\n\n

Cold rolled steel, with its performance advantages, is widely used in multiple core industries:<\/p>\n\n\n\n

    \n
  1. Automotive industry
    Body covering: DC04 deep drawn steel (0.6-1.2mm thick) is used for doors, engine hood, etc.
    Safety structural components: HC340\/590DP high-strength steel (tensile strength \u2265 590MPa) is used to make anti-collision beams.<\/li>\n\n\n\n
  2. Home appliance manufacturing
    Precision components: Cold rolled sheet galvanized (with a zinc layer of 60g\/m \u00b2), used for refrigerator side panels and air conditioning heat sinks.
    Appearance design: Color coated galvanized cold-rolled sheet (PVDF coating \u2265 20 \u03bc m) enhances product aesthetics.<\/li>\n\n\n\n
  3. Architecture and Machinery
    Light steel structure: C-shaped cold-rolled steel (1.5-3.0mm thick) reduces building weight by 30%.
    Tool mold: SK5 high carbon cold-rolled steel with a hardness of \u2265 HRC60 after quenching, used for cutting tools.<\/li>\n<\/ol>\n\n\n\n
