Thin A709 Gr 50 high strength steel, steel plate is mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other departments. The main requirement of thin steel plate is to facilitate bending and forming. The thinner the steel plate is, the easier it is to bend. The common specifications of thin steel plate include thickness less than 4mm, width about 500-1500mm and length about 1.5-4m.

We have a fully advanced and modernized warehouse that stores tonnes of our value-adding A709 Gr 50 high strength steel products, which we source out from the mills that are compliant with the universal guidelines for plate production.
How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, A709 Gr 50 high strength steel, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of A709 Gr 50 high strength steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in A709 Gr 50 high strength steel etc. steel is strictly controlled.
The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel A709 Gr 50 high strength steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system.
