SPCC | Low Carbon Steel Description :

SPCC is a steel grade specified in JIS G 3141 "Cold Rolled Steel Sheet and Strip," and is also called "Commom Steel" because it is an extremely low carbon steel.
Its low Carbon content makes it easy to process, and also suitable for drawing with soft finish.We provide based on our abundant experience and technology cultivated through the production of cold rolled carbon steel strip, we can also manufacture thin strips with thicknesses of under 0.40 mm, foil with thicknesses of under 0.099 mm, and annealed finish (A condition) to full hardened finish (1B or 1D condition) in small lots, which are rarely available in the market.
Because of these characteristics, many of our materials are used for watches, cameras, office equipments, electric appliances, automobiles, and other special precision machineries.

Versatile Applications Across Industries
SPCC Low Carbon Steel is engineered for diverse applications, including watch parts, washers, shims, lead frames, steering parts, connectors, and camera modules. Its adaptability and precision make it an ideal choice for components where dimensional accuracy, formability, and reliable surface quality are paramount.

Wide Range of Thicknesses and Finishes
With thicknesses from 0.030 to 3.0 mm and various tempering options, SPCC steel provides manufacturers with the flexibility to choose the exact mechanical properties and surface appearance required for their specific applications, whether bright or dull.

Commitment to Japanese Quality Standards
We export, manufacture, and supply SPCC Low Carbon Steel that meets Japan's strict quality benchmarks. Customers worldwide benefit from consistent chemical composition, excellent flatness, and uniform surface finishes, ensuring optimal performance for high-precision parts.

FAQ's of SPCC | Low Carbon Steel:

Q: What applications are best suited for SPCC Low Carbon Steel coils and sheets?

A: SPCC Low Carbon Steel is used extensively in the manufacturing of watch parts, washers, shims, lead frames, steering components, thermal protectors, connectors, camera parts, camera modules, and oil rings, particularly where precision and surface finish are crucial.

Q: How is the temper condition of SPCC steel specified and what does it mean?

A: The temper of SPCC steel is indicated as 'A' for Annealed, 'SB/SD' for Skin Passed, and 'As Rolled' with various brightness and dullness levels (8B/8D, 4B/4D, etc.). The choice of temper influences formability and surface appearance, letting manufacturers match steel characteristics to their process requirements.

Q: What is the manufacturing process for SPCC coils and sheets?

A: SPCC steel is manufactured by cold rolling, followed by optional annealing or skin passing depending on the required temper. The surface can be finished as bright or dull, and chemical composition is carefully controlled to guarantee consistency for demanding industrial applications.

Q: When should I choose bright versus dull surface finishes for my application?

A: Bright finishes offer a reflective appearance suitable for visible or decorative parts, while dull surfaces reduce glare and are preferred for applications where non-reflectivity or specific adhesion properties are needed.

Q: Where are SPCC Low Carbon Steel products typically sourced from?

A: Our SPCC steel coils and sheets are produced in Japan, adhering to rigorous quality standards, and are exported and supplied to customers around the globe seeking reliable low carbon steel for industrial use.

Q: What benefits does SPCC Low Carbon Steel provide for precision manufacturing?

A: SPCC steel's consistent thickness, excellent formability, and range of surface finishes allow for high-precision stamping, drawing, and forming. Its low carbon content aids in achieving tight tolerances and smooth edges in end products.
