SPHC Hot Rolled Steel Coil - High-Strength Cold-Forming Carbon Steel Coil

SPHC hot rolled steel coil represents a commercial-quality carbon steel material specifically engineered for cold-forming applications in automotive, construction, and general fabrication industries. Manufactured according to JIS G3131 standards, this hot-rolled product delivers exceptional formability with a tensile strength of 270 MPa minimum, making it the preferred choice for manufacturers requiring reliable deep-drawing characteristics and consistent mechanical properties. Our mill-direct supply ensures cost-effective pricing while maintaining strict quality control throughout production.

What is SPHC Hot Rolled Steel Coil?

SPHC hot rolled steel coil is a low-carbon steel product classified under Japanese Industrial Standards (JIS G3131) as commercial-quality hot-rolled sheet and coil for cold-forming applications. The designation "SPHC" indicates Steel Plate Hot-rolled Commercial quality, featuring carbon content limited to 0.15% maximum to ensure superior ductility during stamping, bending, and deep-drawing operations.

SPHC Hot Rolled Steel Coil Technical Specifications

Our SPHC material complies with JIS G3131:2010 Section 4, featuring tensile strength of 270-370 MPa, yield strength of 205 MPa minimum, and elongation of 34% minimum in 50mm gauge length. The chemical composition maintains carbon at 0.15% maximum, manganese at 0.60% maximum, phosphorus at 0.050% maximum, and sulfur at 0.050% maximum, ensuring consistent weldability and formability across production batches.

Key Advantages of SPHC Steel Coil

This commercial-grade material finds extensive application in automotive body panels, appliance housings, and structural components due to its optimal balance of strength and formability. The hot-rolled surface finish provides excellent paint adhesion, while the controlled chemical composition guarantees uniform mechanical properties essential for high-speed stamping operations. Manufacturers benefit from reduced tooling wear and minimal springback during forming processes.

Manufacturing Process and Quality Control

SPHC coils are produced through continuous hot-rolling at temperatures exceeding 1,200°C, followed by controlled cooling to achieve the specified microstructure. Our production facility maintains ISO 9001:2015 certification and implements real-time thickness monitoring with tolerance of ±0.05mm. Each coil undergoes ultrasonic testing and tensile testing per JIS Z2241 to verify conformance with mechanical property requirements.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ for SPHC hot rolled steel coil is 25 metric tons per specification, with coil weights ranging from 3 to 15 tons depending on thickness and width requirements. Mixed-container orders are available for quantities below 25 tons with adjusted pricing terms.

Do you provide material test certificates?

Yes, we supply EN 10204 Type 3.1 mill test certificates with every shipment, documenting chemical composition analysis, mechanical property test results, and dimensional measurements. Additional third-party inspection by SGS, BV, or TUV can be arranged upon request.

What is the typical delivery time?

Standard delivery time is 25-30 days from order confirmation for stock thickness ranges of 1.2mm to 6.0mm. Custom thickness requirements may extend lead time to 35-40 days depending on production schedule. Express processing is available for urgent orders with 15-day delivery.

Can you cut to custom sizes?

Our processing center offers slitting services to custom widths from 600mm to 1,500mm with tolerance of ±3mm, and cut-to-length services for sheets ranging from 1,000mm to 6,000mm. Blanking and shearing services are available for specific part geometries with CAD file submission.
