01 · 产品概述

SPHC is a hot-rolled low-carbon steel specified in JIS G3131, produced as coil and sheet for general structural and forming applications. Its low carbon content gives excellent weldability, good ductility and a clean surface for economical bending, deep drawing of mild parts, pipe making and general fabrication where strength requirements are moderate.

WHY CHOOSE SPHC

One material, one grade — no mixed chemistries. Consistent low-carbon composition, uniform mechanical properties, cut-to-size service, mill certificates available, and stable stock in standard widths and thicknesses.

02 · 主要特点

Excellent Weldability

Low carbon (≤0.15%) avoids hardening and cracking in MIG, TIG and arc welding — ideal for structural fabrication.

良好的成型性

High elongation (≥27%) supports bending, flanging, shallow drawing and roll forming without cracking.

Tight Dimensional Tolerance

Hot rolling to JIS tolerance classes keeps thickness and width consistent for predictable downstream processing.

Fast Lead Time

Large in-house stock of coils and sheets; 分切, cutting and delivery arranged within days.

Cost Effective

Hot-rolled economics with mild steel performance — the value choice for non-critical structural parts.

Custom Sizes

Sheets cut to your length and width, coils slit to narrow strips, edge trimming available on request.
