Technical key points for the production of 10mm hot rolled S690QL steel plate

19Mn6 steel is common carbon manganese low alloy steel produced according to DIN17155. 19Mn6 steel has strict control over harmful elements sulfur and phosphorus in chemical composition. The mass fraction of sulfur and phosphorus in the steel 10mm hot rolled S690QL steel plate is not more than 0.02%. In addition, vacuum degassing technology is used in smelting, which greatly reduces the gas content in the 19Mn6 steel. 19Mn6 steel has good comprehensive mechanical properties, welding properties and technological properties.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, 10mm hot rolled S690QL steel plate quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the 10mm hot rolled S690QL steel plate International leading steel materials supplier.

Hot rolled 10mm hot rolled S690QL steel plate steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the 10mm hot rolled S690QL steel plate processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

30CrMnSiA steel delivery status: 10mm hot rolled S690QL steel plate, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.
