Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A514 Gr B quenched and tempered steel, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our A514 Gr B quenched and tempered steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge A514 Gr B quenched and tempered steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
Q235 steel is ordinary carbon structural steel, also called Q235 ms plate. Q235 steel plates are popular among a large number of buildings and engineering structures. Q235 steel can be used to make steel bars or to build workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, vessels, ships, etc. Q235 steel is also widely used as A514 Gr B quenched and tempered steel mechanical parts with low performance requirements. Sometimes Q235C steel and Q235D steel can also be used as special steel.
The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of A514 Gr B quenched and tempered steel cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
