SPHC / SPHD / SPHE Carbon Steel Coil

SPHC, SPHD and SPHE pickled & oily hot rolled carbon steel coils are professional deep-drawing base materials graded by JIS G3131. With progressively optimized ductility and ultra-low impurity control, these stamping-grade coils deliver exceptional forming performance from general shallow stamping to complex deep drawing. Widely used for home appliance shells and automotive structural parts, they serve as the core base stock for cold rolling and precision metal stamping factories.

Product Parameters

Types of carbon steel and their properties

Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:

Carbon content (wt.%)	Microstructure	Properties	Examples
Low-carbon steel	< 0.25	Ferrite, pearlite	Low hardness and cost. High ductility, toughness, machinability and weldability
Medium-carbon steel	0.25 – 0.60	Martensite	Low hardenability, medium strength, ductility and toughness
High-carbon steel	0.60 – 1.25	Pearlite	High hardness, strength, low ductility

Core Strengths

Graded stamping performance: SPHC for general stamping, SPHD for deep stamping, SPHE for ultra-deep drawing, covering all forming demands

Ultra-low carbon formula ensures superior ductility, effectively avoids cracking and wrinkling during complex bending and stretching

Pickled & oiled surface removes oxide scale, providing clean substrate for subsequent coating, painting and cold rolling processing

Strict thickness tolerance guarantees consistent forming accuracy for automated stamping production lines

Excellent weldability and surface flatness, reduces post-processing rejection rate for precision parts

Versatile graded substitution for mainstream cold drawing grades, balancing quality and production cost

Scope of Application

Home appliance industry: Refrigerator, air conditioner and washing machine outer & inner casings

Automotive manufacturing: Auto interior brackets, cover panels and shallow/deep drawing structural parts

Precision hardware: Stamped metal fittings, thin-gauge decorative components

Cold rolling substrate: Raw base material for producing SPCC/SPCD cold rolled steel coils

General machinery: Light equipment shells, protective covers and stamped structural accessories
