SAE 1006 ASTM Hot Rolled Mild Carbon Q235 Steel Plate Q345 JIS G3101 SS400

The types of steel plates are usually divided into three types: thick plates (over 6mm), medium-thick plates (3-6mm) and thin plates (below 3mm) according to their thickness. 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 tempering rolling.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.The strength is low, but the plasticity, toughness and cold deformation properties are good. Except for a few cases, it is generally used directly without heat treatment. It is mostly made of steel bars, special-shaped steels, steel plates, etc. There are many uses and a large amount. It is mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, as well as unimportant mechanical parts and general welded parts that do not require heat treatment.
