General Description of S460Q High-strength Steel Plate

EN 10025-6 S460Q High-strength Structural Steel Plate features high yield strength (yield strength ≥ 460 MPa) and excellent low-temperature impact toughness (impact energy tested at -20°C ≥ 30 J). It is primarily used in load-bearing structures such as large engineering machinery, heavy steel structures, special equipment, and heavy-duty vehicles.

Specifications for exported EN 10025-6 S460Q High-strength Steel Plate:Thickness: 3 - 100 mm, Width: 1500 - 2500 mm, Length: 3000 - 12000 mm.

Other specifications can be customized for cutting.

Grade	S460Q
Standard	EN 10025-6: Hot-rolled structural steels - Part 6: Technical delivery conditions for flat products of high yield strength structural steels in the quenched and tempered condition
Classification	Hot-rolled Structural Steel
Delivery Conditions	Quenched and Tempered(Q&T)
Approval By Third Party	ABS, DNV, GL, CCS, LR , RINA, KR, TUV, CE
Weldability	Good weldability, but strict process procedures (Pre-heating, Low Hydrogen Welding Materials, Post-Weld Heat Treatment, etc.) must still be followed during welding. The core risks are cold cracking (hydrogen-induced cracking) and toughness degradation in the heat-affected zone (HAZ).
Machinability	Cutting can be performed using carbide tools, laser, plasma, or flame cutting, but heat input must be controlled to avoid embrittlement in the heat-affected zone. It can undergo cold working such as bending and stamping, but with deformation controlled to prevent performance issues due to stress concentration.
Surface Quality	Default surface in hot-rolled condition. Additional treatments such as shot peening and painting can be required upon request.
Quality Control	Provide the original material certificate. Non-destructive testing (such as UT ultrasonic testing), Charpy V-notch impact test, and Z-direction property test (Grades Z15/Z25/Z35) can be added as required.

Chemical Composition of S460Q High-strength Steel Plate

Grade	S460Q
Element	C	Si	Mn	P	S	Cr	Ni	Mo	Nb	V	Ti	Cu	B	N	Zr
Content (max, %)	0.200	0.800	1.700	0.025	0.015	1.500	2.000	0.700	0.060	0.120	0.050	0.050	0.005	0.015	0.150

* EN 10025-6 S460Q High-strength Steel Plate allows for minor variations in the chemical composition of certain elements depending on the thickness.

Carbon Equivalent of S460Q High-strength Steel Plate

Grade	Thickness (t) [mm]	CEV [max]
S460Q	t ≤ 30	0.47
	30 < t ≤ 50	0.48
	50 < t ≤ 150	0.50

* The carbon equivalent value varies depending on the thickness. The greater the thickness of the steel plate, the higher the upper limit of the allowable carbon equivalent value (CEV).

* Carbon equivalent (CEV) calculation formula (IIW): CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15

* Yuxin Steel has a comprehensive range of EN 10025-6 S460Q high-strength steel plates in stock. For details, please contact us for consultation.

S460Q	3 ≤ t ≤ 50	460	550 - 720	17%	30J (at -20°C, Longitudinal)
	50 < t ≤ 100	440	550 - 720	17%	30J (at -20°C, Longitudinal)
	100 < t ≤ 150	400	500 - 670	17%	30J (at -20°C, Longitudinal)

* The strength of S460Q High-strength Steel Plate slightly decreases as the thickness increases.

Applications of S460Q High-strength Steel Plate

Due to the high yield strength and low-temperature toughness of S460Q High-strength steel plate, it is widely used in the following fields:

1. Heavy engineering machinery: Crane boom structures, excavator chassis, mining equipment frames.

2. Large steel structures: Bridge load-bearing components, beams and columns for high-rise buildings, industrial platforms.

3. Special equipment: Pressure vessels, wind turbine tower flanges, load-bearing structures for railway freight cars.

4. Transportation: Heavy-duty truck frames, key load-bearing components of port machinery.
