SPCC Description :

SPCC is a steel grade specified in JIS G3141 "Cold Rolled Steel Sheet and Strip" and is often referred to as "Common Steel" because it is an extremely low-carbon steel.

Its low carbon content makes it easy to process and highly suitable for deep drawing applications with a soft finish. Leveraging extensive experience and advanced cold-rolled steel strip manufacturing technology, thin strips below 0.40 mm, foil below 0.099 mm, and a wide range of tempers from annealed finish (A condition) to full-hardened finish (1B or 1D condition) can be supplied in small lots, which are rarely available in the market.

Due to these characteristics, SPCC is widely used in watches, cameras, office equipment, electrical appliances, automobiles, and other precision machinery applications.

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.
