SPCC Steel

SPCC (Steel Plate Cold Commercial) is a cold rolled steel plate. It is equivalent to Chinese grades Q195, Q215A and German grade St12. SPCC is produced by subjecting SPHC (hot rolled steel plate) to cold rolling at room temperature. Among cold-rolled steel sheets, it is “general use” and is also called “polished material”, “rolled material”, and “cold” . It is often used in sheet metal processing, and has a wide range of uses, such as being used as parts for watches, cameras, automobiles, etc.

What Is SPCC Steel?

SPCC is called cold-rolled steel plate and is made by cold-rolling SPHC (Steel Plate Hot Commercial). Among carbon steels, the carbon content is less than 0.1%, and it is classified as an SPC material.

SPCC is a steel material for sheet metal and press, and only plate material is not distributed. Most of the board thickness is 0.5 to 3.2mm, and among them, board thickness of 1.6mm and 2.0mm are stable distribution.

SPCC Steel Plate:

Abbreviation for Steel Plate Cold Commercial. Steel sheet rolled at room temperature.

SPCC is also called "rolled material", "cold", and "polished material" because of its smooth surface.

SPHEfor deep drawingSteel plate with uniform material and suitable for deep drawing.SPCEfor deep drawingIt is a steel plate with excellent deep drawability, and because the crystal grains are adjusted metallurgically, it maintains a clean surface even after drawing.

SPCC Steel Specifications

The common specification of SPCC cold rolled sheet is 0.5-3.0 mm*1,250 mm*2,440 mm; The max width and length can reach up to 2,000mm and 6,000 mm.

while the specification of SPCC cold-rolled strip and coil is 0.3-2.5 mm *355-1,500 mm.

What Is SPCC Steel Equivalent to?

As mentioned, SPCC is a cold rolled steel sheet and strip of commercial quality, which is defined in JIS G 3141 standard. Here are some worldwide steel equivalent grades for your reference.

Features of SPCC

SPCC is characterized by high workability and formability among carbon steels.

SPCC has high workability and formability

SPCC is known as a material with high workability and formability due to its low carbon content and softness. Especially suitable for bending and drawing. SPCC is also suitable for welding.

SPCC has a smooth surface

Due to its smooth surface, SPCC is highly decorative and can be painted or plated to achieve a more beautiful appearance.

SPCC is easily oxidized and easily rusts.

SPCC removes the surface oxide film. Therefore, it is easy to oxidize, and it is usually suppressed by applying oil at the time of shipment. In order to prevent oxidation, post-treatments such as painting, anti-corrosion treatment, and plating are indispensable after processing.

Applications of SPCC Metal

SPCC steel is widely used in various applications due to its high strength, durability, and excellent surface finish. Here are some of its applications:

  • Automotive industry: SPCC is used to manufacture automobile parts such as car bodies, engine components, and other structural components;
  • Electrical appliances, such as refrigerators, air conditioners, and washing machines;
  • Construction, such as roofing sheets, wall panels, and other structural components;
  • Packaging materials, such as cans, drums, and containers.
  • Furniture, such as cabinets, shelves, and tables.
  • Industrial equipment: to manufacture various industrial equipment such as machinery parts, toolboxes, and storage racks.

Differences between SPCC and SPHC

The difference between SPCC and SPHC is the temperature range during manufacturing. SPHC is hot-rolled, and SPCC is cold-rolled SPHC, and their properties are very different.

“SPCC” is often selected when accuracy is prioritized, and “SPHC” is often selected when cost is prioritized.

Cost comparison

SPCCSPCC is manufactured by further cold-rolling SPHC (at a temperature at which recrystallization does not occur), so work hardening occurs.
Compared to SPHC, a greater force is required for processing, and the number of manufacturing processes increases, resulting in higher costs.
SPHCSPHC is produced by hot rolling (higher than the recrystallization temperature), so there is no work hardening.
The manufacturing cost is also low, and it is possible to obtain it cheaply unless it has a special thickness.

Accuracy comparison

SPCCSPCC is characterized by small temperature changes in the material and high dimensional accuracy.
It is possible to manufacture thinner sheets than SPHC.
SPHCSPHC does not have high dimensional accuracy due to material temperature changes.

Conclusion

SPCC stands for “Steel Plate Cold Rolled Commercial,” and it refers to a grade of cold rolled steel. Its excellent formability, strength, and resistance to rust and corrosion make it a popular choice for a variety of applications. If you have any questions, please feel free to contact us!
