Structural grades — chemical composition

Grade	C max. %	Mn max. %	Si max. %	P max. %	S max. %
Q235B / GB/T 700	0.20	1.40	0.35	0.045	0.045
S355JR / EN 10025-2	0.24	1.60	0.55	0.035	0.035

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.

ASTM A36

ASTM A36 — chemistry for plate cut from coil

Plate thickness (in.)	C max. %	Mn %	P max. %	S max. %
≤⅜	0.25	Not specified	0.04	0.05
>⅜–1½	0.25	0.80–1.20	0.04	0.05

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

Property	Metric	Imperial
Tensile strength	400–550 MPa	58,000–79,800 psi
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

Thickness t (mm)	Yield ReH min. (MPa)	Tensile Rm (MPa)	Elongation A min. (%)
1.2–16	235	370–500	26
>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
≤60	1.0a	1.5a
>60–100	2.0a	2.5a
>100	By agreement	By agreement

a is specimen thickness; bend specimen width is 2a. Test requirements and sampling follow GB/T 700-2006.

Frequently asked questions

What should I include in my enquiry?

Send the product, grade or standard, dimensions, quantity, required finish and destination. Describe the end use if the specification is still being developed.

Can I request a particular size or finish?

Yes, include your required size and finish in the enquiry. Availability and any processing requirements must be confirmed in the quotation.

How are minimum order and lead time confirmed?

They depend on grade, dimensions, processing and quantity. We confirm them for the particular order rather than publish one figure for every product.

What documents should I request?

State the material test document, inspection scope and other purchasing documents required for your project. Agree these with the order.
