ASTM A572 Gr.55 Alloy Carbon Steel Plate  

The steel sheet is flat, rectangular and can be directly rolled or cut from wide steel strips. The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm. Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling. 1. Hot Rolled Steel Plate Hot rolling processing methods include hot rolling, forging, extrusion and other methods. 2. Cold Rolled Steel Plate Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods. The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.has similar chemistry a…
