A572 Gr 50 carbon steel material,Q345R steel is common low alloy steel, which is commonly used for boiler and pressure vessel. The delivery status includes hot rolling or normalizing. Q345R steel yield strength is 265-345MPa, tensile strength is 510-640MPa, elongation is greater than 21%, and zero degree V-shaped impact energy is greater than 34J. Q345R steel standard is GB713. Q345R steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R steel is slightly lower than that of low alloy high strength steel plate.A572 Gr 50 carbon steel material

A572 Gr 50 carbon steel material,The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
