Product Introduction

1. What Is Cold Rolled 1/4 Hard Steel?

Cold Rolled 1/4 Hard Steel is produced through cold reduction followed by controlled temper rolling to achieve a specified hardness condition. Under JIS G 3141, the temper designation "4" represents 1/4 hard, while SPCC is classified as commercial quality cold rolled steel. This combination is commonly considered for components requiring a harder material condition than standard temper products. Raysteel Resource offers sourcing options from Shougang, Benxi Steel, Xintiansteel, Angang, and Baosteel, subject to mill production capabilities and order confirmation.

2. Which Cold Rolled Steel Grade Is Suitable for Your Application?

The correct grade depends on the forming process and finished component requirements. SPCC is generally used for commercial quality applications, while SPCD is intended for drawing operations and SPCE is designed for deep drawing applications under JIS G 3141. For buyers working with European specifications, DC01, DC03, and DC04 are established cold forming grades under EN 10130. These designations have different technical requirements and should not be treated as direct equivalents. Before ordering, confirm the grade, applicable standard, temper condition, and intended manufacturing process.

3. How Does 1/4 Hard Temper Affect Steel Processing?

Temper condition has a direct influence on the working characteristics of cold rolled steel. SPCC 1/4 hard is harder than standard temper SPCC, making it worth considering for applications where greater resistance to deformation is required. However, higher hardness can also affect bending radius, springback, and forming limits. Buyers should evaluate the material against the actual component design rather than selecting a temper based on hardness alone. If your production involves stamping, roll forming, or repeated bending, provide the required thickness, tooling conditions, and processing details so the appropriate grade and temper can be reviewed before purchasing.

4. What Quality Details Should You Check Before Purchasing?

A cold rolled steel quotation should identify more than the nominal thickness and unit price. Buyers should check thickness tolerance, width, surface finish, edge condition, temper designation, hardness, and applicable mechanical properties. For SPCC 1/4 hard material, the temper code should be clearly specified in the purchase order and checked against the relevant JIS G 3141 technical reference. For European grade requirements, buyers can consult the EN 10130 grade information. For US projects, refer to the ASTM A1008/A1008M standard. A Mill Test Certificate (MTC) should be reviewed to verify the actual production batch, chemical composition, and applicable test results. Raysteel Resource can coordinate documentation and inspection requirements according to the confirmed mill and order specification.

5. Request a Cold Rolled Steel Quotation from Raysteel Resource

Choosing the right cold rolled steel involves matching the material specification with your production requirements. Differences in grade, temper, thickness, width, surface condition, and mill source can influence both processing performance and purchasing cost. Raysteel Resource provides sourcing options from Shougang, Benxi Steel, Xintiansteel, Angang, and Baosteel in China, with the actual producing mill confirmed for each order. To receive a quotation, send us your required grade, temper designation, dimensions, quantity, destination port, and applicable standard. If you have a technical drawing or material specification sheet, you can also share it for review. This helps us identify a suitable supply option and prepare an offer based on your actual requirements.
