The market situation of A514 Gr E steel material

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, A514 Gr E steel material, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

A514 Gr E steel material, 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.

In recent years, in line with the development trend of iron and A514 Gr E steel material steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A514 Gr E steel material are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as A514 Gr E steel material. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.
