What is JIS G 3141?

JIS G 3141 SPCC-SD is a specific grade of cold-rolled carbon steel sheet/strip defined by the Japanese Industrial Standards (JIS).

JIS G 3141 is a Japanese material standard for cold rolled steel.

JIS G 3141: The official Japanese standard title is Cold-reduced carbon steel sheets and strip.

SPCC: An acronym for Steel Plate Cold Commercial. It signifies commercial-quality, general-purpose cold-rolled steel.

-S: Stands for Standard Temper, indicating the material is supplied in the annealed and skin-rolled (temper-rolled) condition.

-D: Stands for Dull finish, meaning the steel has a matte, non-reflective, textured surface (also known as a "dull finish" or "shot blast finish").

Notes
1. The thickness of a steel strip is typically measured at a point within 15 mm of the edges. For pieces less than 30 mm in width, thickness is measured at the center.
2. To order sizes not listed above, please feel free to contact us.
3. Costs are higher for products made to meet special standards (SS and U).

FAQ

1. What does SPCC-SD stand for?

SPCC-SD refers to commercial-quality, cold-rolled carbon steel. The "S" denotes standard tempering (annealed and skin-passed), and "D" specifies a Dull Finish (a matte, grainy surface).

2. Why is a "Dull Finish" (SD) important?

The matte surface is intentionally created to improve oil retention during stamping and to provide superior paint adhesion compared to bright or smooth finishes.

3. What are the mechanical properties of SPCC-SD?

It is a soft, ductile steel with a minimum tensile strength of 270 MPa. It is designed for general-purpose forming, bending, and moderate drawing applications.

4. How does SPCC-SD compare to SPCC-SB?

While both are the same material grade, SPCC-SD has a matte finish, whereas SPCC-SB has a Bright Finish (smooth and shiny), usually preferred for decorative plating or when no painting is required.

5. What are common international equivalents?

Common equivalents include ASTM A1008 CS (USA), EN 10130 DC01 (Europe), and GB/T 5213 DC01 (China).
