The difference between S460ML VS S460nl, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. S460ML VS S460nl, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.

S460ML VS S460nl, Q345B low alloy plate performance: 1) High strength: Generally its yield strength is above 300MPa; 2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required; 3) Good welding performance and cold forming performance; 4) Low cold brittle transition temperature; 5) Good corrosion resistance.
The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S460ML VS S460nl EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
