Junying Metal Manufacturing Co., Limited works extensively with SPHC steel and its equivalent grades across multiple industries including automotive, construction, and general manufacturing. SPHC is a hot-rolled steel grade commonly used in applications where forming and welding are the primary processing methods. The full form of SPHC is Steel Pickling Hot rolled Commercial, a designation originating from Japanese industrial standards JIS G3131. This material is characterized by its relatively low carbon content, typically around 0.15 percent maximum, which gives it excellent formability and weldability while maintaining adequate strength for structural applications. Understanding the SPHC material equivalent grades available in different standards such as ASTM, DIN, GB, and EN is essential for engineers and procurement professionals working with international specifications. Junying processes SPHC steel and its equivalents to produce precision components across a wide range of applications, leveraging years of experience in hot-rolled steel fabrication and machining.
SPHC Material Properties and Applications
SPHC steel offers a balanced combination of mechanical properties that make it suitable for a variety of industrial applications. The material has a tensile strength ranging from 270 to 410 MPa, with elongation typically above 28 percent, indicating good ductility for forming operations. These properties make SPHC ideal for automotive body panels, chassis components, structural tubing, and general sheet metal fabrication. After pickling, the material surface is clean and suitable for further processing including cold rolling, galvanizing, or direct painting. Junying’s manufacturing capabilities include laser cutting, CNC bending, welding, and precision machining of SPHC steel components, with in-house quality control to verify material properties and dimensional accuracy. The company’s material expertise allows it to recommend appropriate SPHC equivalent grades when clients specify standards from different regions, ensuring that material substitutions are technically valid and performance-appropriate.
SPHC Equivalent Grades Across International Standards
The selection of the correct sphc material equivalent is critical for projects involving cross-border material specifications. Engineers frequently need to substitute SPHC with equivalent grades from other standards when sourcing materials globally. The following table summarizes the common equivalents for SPHC steel across major international standards:
| Standard | Equivalent Grade | Key Characteristics | Common Applications |
|---|---|---|---|
| JIS G3131 | SPHC | Hot-rolled, pickled, commercial quality | Automotive, construction |
| ASTM A1011 | CS Type B | Commercial steel, similar carbon range | General fabrication |
| DIN EN 10111 | DD11 (1.0332) | Hot-rolled forming steel | Structural components |
| GB/T 710 | SPHC equivalent (China) | Similar composition and properties | Domestic manufacturing |
| BS EN 10025 | S235JR | Structural steel with comparable strength | General engineering |
| ISO 3573 | HR1 | Hot-rolled commercial quality sheet | Industrial applications |
