Product details

Hot rolled steel coil for slitting or cut-to-length processing needs a finished-size schedule as well as a material grade. Separate the master coil dimensions from the required slit widths or sheet lengths. Include edge condition, tolerances and coil-handling limits so the quotation covers the material and the processing scope.

Coiled hot rolled steel for further processing, forming and fabrication. Share your target grade, width, thickness and coil requirements.

Supply availability and the final specification are confirmed in the quotation. Please include the intended application, dimensions, quantity and destination when contacting us.

Processing route

Tell us whether the coil will be slit, levelled, cut or formed.

Coil handling

Specify coil weight and inner diameter for your equipment.

Surface condition

Discuss the required surface and any further finishing process.

Q235B carbon may be agreed up to 0.22%. Product analysis, thickness and other element requirements depend on the ordered standard. The grades are not interchangeable.

Structural grades — strength and impact

Grade	Thickness basis	Yield min. (MPa)	Tensile (MPa)	Impact designation
Q235B	≤16 mm	235	370–500	27 J at +20°C, subject to standard exemptions
S355JR	>3–16 mm	355	470–630	27 J at +20°C

Yield strength decreases at larger thickness for Q235B/S355JR. Specify thickness, specimen orientation and test requirements; do not apply this thin-plate row to all gauges.

Grade-specific technical data

Select the exact grade to view its composition, mechanical properties and test conditions. Grades and standards are not interchangeable; confirm the ordered edition and delivery condition. These reference tables are not a live stock list.

ASTM A36

ASTM A36 — chemistry for plate cut from coil

A36 plate ordered cut from coil: applicable thickness bands within the listed 1.2–25 mm coil range. Copper-bearing option: Cu ≥0.20%. Other product forms follow their own ordered specification; values are not generic to every coil grade.

ASTM A36 — mechanical properties

Yield strength, minimum	250 MPa	36,300 psi
Elongation, 200 mm / 8 in. gauge length	20%	20%
Elongation, 50 mm / 2 in. gauge length	23%	23%

ASTM A36 only. Elongation depends on specimen gauge length, product dimensions and the ordered specification; values do not apply to Q235B or EN grades.

ASTM A36 — physical and elastic properties

Property	Metric	Imperial
Density	7.85 g/cm³	0.284 lb/in³
Elastic modulus	200 GPa	29,000 ksi
Bulk modulus	140 GPa	20,300 ksi
Poisson’s ratio	0.260	0.260
Shear modulus	79.3 GPa	11,500 ksi

Typical room-temperature reference properties, not additional guaranteed acceptance tests. Apply to A36 material only.

S355JR / EN 10025-2

S355JR — full chemical composition (%)

Grade	C max.	Si max.	Mn max.	P max.	S max.	N max.	Cu max.
S355JR	0.24	0.55	1.60	0.035	0.035	0.012	0.55

Heat analysis; thickness within the listed coil range. Nitrogen exemptions and copper options depend on the ordered standard.

S355JR — strength by coil thickness

Thickness (mm)	Yield min. (MPa)	Tensile strength (MPa)	Impact designation
1.2–3	355	510–680	JR: 27 J at +20°C
>3–16	355	470–630	JR: 27 J at +20°C
>16–25	345	470–630	JR: 27 J at +20°C

Only thickness bands within this product’s 1.2–25 mm range are shown. Impact testing is subject to specimen size and the standard’s exemptions.

Q235B / GB/T 700-2006

Q235B — chemical composition (heat analysis)

C max. %	Si max. %	Mn max. %	P max. %	S max. %
0.20	0.35	1.40	0.045	0.045

GB/T 700-2006, as reproduced in the PolyU Chinese Steel Guide, Appendix C. Carbon up to 0.22% is permitted only by agreement with the purchaser.

Q235B — hot-rolled coil mechanical properties

>16–25	225	370–500	26

Thickness bands are limited to this product’s 1.2–25 mm range. For wide strip and plate cut from it, the upper tensile limit is not an acceptance requirement under GB/T 700-2006.

Q235B — impact and delivery condition

Item	Requirement
Quality class	B
Charpy V-notch test temperature	+20°C
Impact energy	27 J minimum, standard test basis
Thin material exception	For thickness <25 mm, omission of impact testing requires the supplier guarantee and purchaser agreement allowed by the standard
Delivery	Hot rolled; controlled rolling or normalized delivery where specified in the order

The impact requirement is specific to Q235B; do not substitute values from Q235A, Q235C or Q235D.

Q235B — 180° cold-bend requirements

Thickness a (mm)	Longitudinal mandrel diameter d	Transverse mandrel diameter d

Frequently asked questions

What should I specify for a hot rolled coil slitting order?

List the steel grade and standard, thickness, finished strip widths, width tolerances and quantity per width. State acceptable edge condition and burr limits where required. Include coil inner diameter and weight limits for your equipment, and identify whether the quotation should cover master coils or processed strips.

How is a cut-to-length coil order different from a plate order?

Provide the required finished sheet lengths, width, thickness and quantity, plus flatness and squareness requirements. Identify any levelling or edge processing needed. Do not assume a coil-derived sheet meets every requirement of a separately specified plate product; confirm the applicable grade, product standard and delivery condition.

How are minimum order and lead time confirmed?

Send your grade, size, tonnage and required delivery date. Ask for separate confirmation of stock availability, any production or processing time, and the dispatch date. Transit time depends on destination and shipment terms; the agreed quotation should state the minimum quantity and schedule.

What documents should I request?

List the required material test report, inspection document type and any third-party inspection in your enquiry. Ask which documents apply to your selected material and agree their scope before ordering. A general company certificate does not replace the material test results for the supplied heat or coil.
