After adding a small amount of niobium, vanadium and titanium to A514 Gr Q structural steel material etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, A514 Gr Q structural steel material quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the A514 Gr Q structural steel material International leading steel materials supplier.
The difference between low alloy high strength steel plate and carbon steel plate, A514 Gr Q structural steel material:(1) Strength difference between low alloy high strength steel plate and carbon steel plate:The strength of low alloy high strength steel plate is higher than that of carbon steel plate;(2) Hardness difference between low alloy high strength steel plate and carbon steel plate:The hardness of low alloy high strength steel plate is higher than that of carbon steel plate;(3) Usage difference between low alloy high strength steel plate and carbon steel plate:The application range of low alloy high strength steel plate is wider than that of carbon steel plate.
As an important classification of steel, A514 Gr Q structural steel material hot rolled steel coil has the following advantages: first, hot rolled steel coil can be curled at will, reducing the occupied space, and it is convenient for transportation. Second, the processing of hot rolled steel coil is flexible and convenient. For spiral welded pipe, coil uncoiling, leveling, trimming, forming and welding are used. For longitudinal welded pipe, it must be formed and welded with steel plate. The hot rolled steel coil price is affected by the size and specification. The prices of different specifications and thickness A514 Gr Q structural steel material, hot rolled steel coils are different.
