Necessary for making sheet metal! Detailed explanation of cold rolling steel characteristics

Product Name: cold rolling steel

Code: SPCC, CRS (SPCD: cold plate for drawing, SPCE cold plate for deep drawing)

Hardness: hRb1 / 2H = 74 ~ 89 1 / 4H = 65 ~ 80 1 / 8h = 50 ~ 71 H = 89 or above tensile strength: more than 28kgf / mm.

Material thickness: 0.25 ~ 3.2mm. For materials above 3.2mm, the material width must be customized: the maximum width is 5 ‘(1524mm), which is generally 4’, i.e. 1219mm or 1250mm. Any size less than 1524mm can be cut as needed.

Material length: any size can be cut as required. Generally 8 ‘, i.e. 2438mm or 2500mm.

Material characteristics: 1. It has iron gray luster, and the surface is easy to scratch and rust. During processing, pay attention to protection and quickly turn the order.

  1. Suitable for electroplating (colorful zinc plating, white zinc plating, nickel plating, tin plating…), paint baking, powder spraying, etc. Specific gravity: 7.85. Weight calculation: length (m) × Width (m) × Thickness (mm) × Specific gravity = kilogram (kg), e.g. spcc2 0 × 1220 × 2440 weight: 2.0 × 1.22 × 2.44 × 7.85 = 46.74kg, another example: spcc1 0 × 1000 × 2000 weight: 1 × one × two × 7.85 = 15.7kg note: 1. The general tolerance of material thickness is + 0, – 0.08, that is, the measured plate thickness is 2.0mm, which may be only 1.92mm.
  2. A micrometer shall be used to measure the material thickness, and a cursor caliper shall not be used.
  3. In order to prevent the plate from rusting, the surface of the workpiece can be lightly coated with antirust oil after processing, or the workpiece can be covered with tarpaulin.
