General Description of S460QL High-strength Steel Plate

EN 10025-6 S460QL High-strength quenched and tempered structural steel plate is primarily used in heavy-duty structures, engineering machinery, bridges, and other fields that require high material strength, low-temperature toughness, and weldability.

Specifications for exported EN 10025-6 S460QL High-strength Steel Plate:Thickness: 3 - 100 mm, Width: 1500 - 2500 mm, Length: 3000 - 12000 mm.

Other specifications can be customized for cutting.

Grade	S460QL
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	Cold working such as bending and stamping requires controlling the deformation rate to avoid the formation of cracks.
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 S460QL High-strength Steel Plate

Grade	S460QL
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 S460QL High-strength Steel Plate allows for minor variations in the chemical composition of certain elements depending on the thickness.

Carbon Equivalent of S460QL High-strength Steel Plate

Grade	Thickness (t) [mm]	CEV [max]
S460QL	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

Mechanical Properties of S460QL High-strength Steel Plate

Grade	Thickness (t) [mm]	Yield Strength (ReH) [min, MPa]	Tensile Strength (Rm) [MPa]	Elongation (A) [min, %]	Impact Energy (KV) [min]
S460QL	3 ≤ t ≤ 50	460	550 - 720	17%	30J (at -40°C, Longitudinal)
	50 < t ≤ 100	440	550 - 720	17%	30J (at -40°C, Longitudinal)
	100 < t ≤ 150	400	500 - 670	17%	30J (at -40°C, Longitudinal)

* The strength of S460QL High-strength Steel Plate slightly decreases as the thickness increases.

Applications of S460QL High-strength Steel Plate

EN 10025-6 S460QL High-strength Steel Plate is characterized by high strength and high toughness, and is widely used in structures requiring weight reduction or heavy load-bearing. Its main applications include:

1. Construction machinery: booms, frames, and track shoes of excavators, cranes, and loaders.

2. Bridge structures: load-bearing beams and connecting plates for long-span highway/railway bridges.

3. Marine engineering: support structures and jackets for offshore platforms (additional anti-corrosion treatment required).

4. Heavy-duty vehicles: frames and suspension systems of mining trucks and special transport vehicles.

5. High-pressure vessels and storage tanks: steel containers subjected to high pressure (e.g., chemical storage tanks, hydraulic reservoirs).

6. Mining machinery: wear-resistant structural components of crushers and roadheaders.

Comparison of Similar Grades

Grade	Yield Strength (ReH) [min, MPa]	Tensile Strength (Rm) [MPa]	Impact Energy (KV) [min]	Typical Application Scenarios
S460Q	460	550 - 720	30J (at -20°C)	Conventional engineering machinery, steel structure workshops
S460QL	460	550 - 720	30J (at -40°C)	Bridges in cold regions, pressure vessels
S460QL1	460	550 - 720	30J (at -60°C)	Arctic equipment, ultra-low temperature storage tanks

* The differences between S460Q, S460QL, and S460QL1 mainly lie in the impact temperature requirements.

Equivalent Standard Replacement Solution
