Hot Rolled Steel Coil Product Specification

1. Product Overview

Hot Rolled Steel Coil (HRC) is produced from continuous casting slab. After heating at high temperature of 900~1250℃, rough rolling, finish rolling, laminar cooling and coiling, the finished coil is supplied with natural oxide scale under ambient temperature. It serves as the core raw material for construction, machinery, automobile and pipe processing industries.

Delivery condition: Original hot rolled black coil without coating. Pickling, leveling, slitting and galvanizing processing are available per customer’s requirement.

2. Dimension Specification

Thickness: 1.2mm～25.4mm, regular stock range: 2.0～12.0mm
Width: 800mm～2130mm, common sizes: 1000/1250/1500/1800mm
Coil weight: 8～32MT per coil, regular weight:18～28MT
Inner coil diameter: 760mm (standard mandrel size)
Dimension tolerance complies with GB/T709-2019: thickness tolerance ±0.15mm, width tolerance ±3mm; flat shape with coil camber ≤50mm.

3. Main Grades & Executive Standards

1) Ordinary Carbon Steel (for construction, welded pipe & steel structure)

GB Grade	EN Grade	JIS Grade	ASTM Grade	Standard
Q235B	S235JR	SS400	A36	GB/T700,EN10025,JIS G3101,ASTM A36
SPHC(Cold rolled substrate)	DD11	SPHC	A1018	GB/T3524,JIS G3131

2) Low Alloy High Strength Steel (engineering machinery, truck frame & container)

GB Grade	EN Grade	JIS Grade	ASTM Grade	Standard
Q355B/C/D	S355JR	SM490	A572Gr50	GB/T1591,EN10025,JIS G3106,ASTM A572
510L/610L(Auto frame steel)	QStE420TM	SAPH440	-	GB/T3273

3) Special steel: shipbuilding steel, line pipe steel, gas cylinder steel & weathering steel available on customized order.

4. Chemical Composition (Ladle Analysis, wt%)

Q235B Carbon Steel

C:0.12~0.22; Si:≤0.30; Mn:0.30~0.70; S≤0.045; P≤0.045

Q355B Low Alloy Steel

C:≤0.24; Si:≤0.55; Mn:1.00~1.60; S≤0.040; P≤0.040; trace Nb/V alloy element

5. Mechanical Properties (Ambient Test)

Grade	Yield Strength Rp0.2(MPa)	Tensile Strength Rm(MPa)	Elongation A(%)	Bending Property
Q235B	≥235	375~500	≥25	No crack after 180° bend
Q355B	≥355	470~630	≥21	No crack after 180° bend
SPHC	≥220	330~430	≥32	Excellent stamping & bending performance

Test standards: GB/T228.1 for tensile test, GB/T232 for bend test. Mill Test Certificate (MTC) is issued per heat batch.

6. Product Advantages

Cost-effective: Lower production cost than cold rolled coil with obvious procurement cost advantage.
Fine workability: Available for cutting, bending, stamping, welding, drilling and pipe rolling with high finished product rate.
Wide applicability: Direct usable for fabrication and raw material for CR coil, galvanized sheet and welded pipe.
Stable material: Produced by continuous hot rolling line with uniform metallographic structure and stable batch performance.
Surface feature: Original blue-grey oxide layer is normal hot rolled status; no harmful defects such as crack, lamination, scarring and inclusion. Slight oxide skin is acceptable.

7. Application Fields

Construction: Steel workshop structure, bridge support, solar bracket, scaffold and embedded parts.
Machinery manufacturing: Equipment base, flange, engineering machinery housing and stamping spare parts.
Automobile industry: Truck frame, cargo floor and auto structural parts (510L/610L exclusive grade).
Pipe processing: ERW pipe, spiral welded pipe, water supply & drainage steel pipe.
Container & tank: Container side panel, gas storage tank and wind tower plate.
Cold rolling substrate: SPHC for cold rolling mill to produce CR sheet and galvanized base material.

8. Packing, Marking & Shipment

Packing: Each coil wrapped with waterproof kraft paper + PE film and fixed by steel strips; bare coil loaded into container.
Marking: Grade, dimension, coil weight, heat No., batch No., standard and mill logo marked on coil label for traceability.
Loading Port: Tianjin Port; spot goods delivered directly from Liaocheng warehouse.
Lead Time: 5~7 days for spot shipment; 10~15 days for customized production order.

9. Order & Payment Terms (Foreign Trade)

MOQ: ≥5MT; full 20GP container load:25MT.
Payment: 30% TT advance payment, balance remitted against copy of Bill of Lading. LC is unacceptable.
Shipping documents: Mill Test Certificate(MTC), Packing List, Commercial Invoice & Certificate of Origin.

10. Remarks

Further processing service available: cut-to-length plate, slitting narrow strips and pickling for oxide removal.
Customized specification available for special thickness/width, low temperature impact requirement(Q355D/E) and certified ship steel.
Quality guarantee: Original mill products. Quality claim can be re-inspected within 7 working days per national standard.
