Hardened Mild Wear Resistant Steel Plate ASTM A131 S335 Corrosion Resistance

A type of material that uses a large amount of steel plates is divided into ordinary low-carbon steel plates and special steel plates, including low-alloy high-strength steels and corrosion-resistant and heat-resistant multi-layer steel plates. Ordinary low-carbon steel plates are divided into two types: cold-rolled and hot-rolled. Cold-rolled steel plates have good surface quality and accurate thickness dimensions. They are mostly used to make car bodies. Hot-rolled plates are mostly used to make car frames and the like. The types of steel plates are usually divided into three types according to their thickness: thick plates (above 6mm), medium-thick plates (3-6mm) and thin plates (below 3mm). In terms of plate-making process, low-carbon steel plates can be divided into two types: cold-rolled and hot-rolled. Hot rolling alone can produce low-carbon steel plates of about 1.2mm and stainless steel plates of about 2mm. Thinner plates can be manufactured by cold rolling, annealing, and quenching and tempering.
In comparison between steel plates, generally hot rolled steel plates are slightly harder than cold rail steel plates and have lower elongation. In the cold-rolled steel sheet, the higher the grade, the softer the steel, the lower the yield point, the larger the n value and the r value, and the larger the total elongation. In addition to the above-mentioned plastic deformation properties, in terms of elastic properties, the modulus of elasticity of steel plates is twice larger than that of aluminum plates. This is beneficial to reduce the spin-forming net bomb, and correspondingly improve the rigidity of the part. This advantage is compelling
