JIS SPHC Nonresulfurized Carbon Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Name:** JIS SPHC Nonresulfurized Carbon Steel, Hot Rolled **Overview** JIS SPHC is a **general-purpose, low-carbon, nonresulfurized steel** specified in the Japanese Industrial Standards (JIS). It is a **commercial quality, hot-rolled mild steel** primarily intended for applications that require excellent cold formability and where surface finish is not a critical factor. The designation indicates its basic characteristics: **"S"** for Steel, **"P"** for Plate, **"H"** for Hot rolled, and **"C"** for Commercial quality. The key feature is its **"nonresulfurized"** nature, meaning it has standard or moderately low sulphur content, which differentiates it from free-machining steels but does not inherently imply ultra-low sulphur. SPHC is a fundamental commodity steel used across numerous manufacturing sectors due to its low cost, good ductility, and ease of fabrication. **Key International Standards & Designation** * **Primary Standard:** **JIS G 3131:2022** - Hot-rolled mild steel plate, sheet and strip. * **Grade Designation:** **SPHC** * **S:** Steel (Kō). * **P:** Plate (板, Ita). * **H:** Hot rolled (熱間圧延, Nekkan Atsuen). * **C:** Commercial quality (Commercial). * **Standard Family:** SPHC is part of a series including SPHD (drawing quality) and SPHE (extra-deep drawing quality), with SPHC being the most basic. * **Common International Equivalents:** * **ASTM:** **A36** (closest in terms of general-purpose application, though A36 often has specified mechanical properties). Also comparable to **SAE 1006/1008** grades in terms of chemistry. * **DIN/EN:** **DC01** (cold-rolled equivalent) or **S235JR** (structural equivalent, but with property guarantees). * **GB/T:** **Q195** or **SPHC** (directly adopted designation). **Chemical Composition (Ladle Analysis, % by weight, typical ranges)** * **Carbon (C):** **≤ 0.15%** (Very low, ensures softness and formability). * **Manganese (Mn):** **≤ 0.60%** (Low). * **Phosphorus (P):** **≤ 0.050%** * **Sulphur (S):** **≤ 0.050%** (This is "nonresulfurized" but not ultra-low. For significantly lower S, grades like SPHT are specified). * **Note:** Composition is typically not rigorously guaranteed for SPHC; it is a chemistry band material. Mechanical properties are not strictly specified, making it a "chemistry grade" rather than a "property grade." **Physical & Mechanical Properties (Typical for hot-rolled condition)** *As a commercial quality steel, mechanical properties are not guaranteed by the standard.* Typical values are provided by producers for reference. * **Yield Strength (YP):** **≈ 180 - 240 MPa** (Not guaranteed). * **Tensile Strength (TS):** **≈ 280 - 380 MPa** (Not guaranteed). * **Elongation (El):** **≈ 28% - 40%** (Varies with thickness; not guaranteed). * **Hardness (HRB):** **≈ 50 - 70**. * **Density:** **7.85 g/cm³**. **Product Features** 1. **Excellent Cold Formability:** Its low carbon content makes it very soft and ductile, ideal for bending, roll-forming, stamping, and simple drawing operations. 2. **Good Weldability:** Very low carbon equivalent allows for easy welding with all common methods without pre-heating. 3. **Cost-Effective:** The most economical grade in the hot-rolled mild steel family, suitable for a vast number of non-critical applications. 4. **Surface Finish:** Typically supplied with a **hot-rolled mill scale** surface. It is not intended for applications requiring a smooth, clean surface without further processing (e.g., pickling). **Typical Applications** SPHC is used in a wide array of general manufacturing and construction where specific strength or surface requirements are not paramount. * **General Fabrication:** **Cabinets, guards, covers, brackets, and non-structural frames**. * **Automotive:** **Non-exposed structural parts, inner panels, and reinforcements**. * **Construction & Furniture:** **Shelving, ductwork, simple furniture frames, and roofing/ siding after forming**. * **Pipe & Tube Manufacturing:** As a feedstock for **welded pipes and tubes**. * **Stampings & Hollow-ware:** **Simple stamped parts, pans, and trays**. **Available Forms & Processing** * **Forms:** **Hot-rolled sheets and strips** (in coils or cut lengths), and **plates**. * **Surface Condition:** **Hot-rolled, with mill scale (Black)**. It is the standard feedstock for **pickling lines** to produce pickled and oiled (PO) material. * **Processing:** Ideal for **shearing, punching, bending, and roll-forming**. Can be easily **welded (spot, arc, gas)**. Not recommended for applications requiring high strength or a pristine painted surface without descaling. --- **Critical Selection & Procurement Note** * **No Guaranteed Mechanical Properties:** This is the most crucial point. SPHC is sold primarily on its chemical composition. **Design cannot rely on minimum yield or tensile strength values.** For structural applications with design calculations, property-guaranteed grades like **SM490A** or **SS400** (JIS) or **S235JR/S355JR** (EN) must be used. * **"Nonresulfurized" Meaning:** This indicates it is not a free-machining steel (like SUM grades with high S). It does not mean it has extra-low sulphur for superior formability; for that, specify **SPHD** or **SPHE**. * **Surface:** The presence of mill scale must be considered. For painting or plating, the scale must be removed by pickling, shot blasting, or grinding. * **Procurement:** Orders should specify thickness, width, coil weight (if applicable), and reference **JIS G 3131 SPHC**. Confirm with the supplier if typical property data is available for reference, but not for design guarantee. -:- For detailed product information, please contact sales. -: JIS SPHC Nonresulfurized Carbon Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5845 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: JIS SPHC Nonresulfurized Carbon Steel Properties -:- For detailed product information, please contact sales. -:
