A514 grade Q quenched and tempered steel,ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.
A514 grade Q quenched and tempered steel,The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel . Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.A514 grade Q quenched and tempered steel
As the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the from cutting cracks, preheating should be carried out before A514 grade Q quenched and tempered steel cutting. Special attention should be paid to preheating to make the entire interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A514 grade Q quenched and tempered steel cannot be preheated, the partial preheating method can be used instead.
