A633 Grade D carbon-manganese-silicon steel 3500 width steel plate production line

Our 12Cr2Mo1VR steel plate breaks through the specification limit, with a thickness of A633 Grade D carbon-manganese-silicon steel up to 180 mm and a single weight of 43.7 tons. The flaw detection can meet the highest level of NB / T47013 flaw detection level. Its thickness and unit weight exceed the production limit of vanadium steel. The 12Cr2Mo1VR steel plate with such specifications has high technical requirements, severe performance requirements, and great production difficulties. In the A633 Grade D carbon-manganese-silicon steel production process, it is easy to appear the tail area defects, which will cause the steel plate to fail inspection. So please choose your suppliers carefully.

In the process of high-speed rolling of wear-resistant steel plate, A633 Grade D carbon-manganese-silicon steel, the temperature of rolling oil of wear-resistant steel plate will change due to the change of environment temperature and rolling pass, and the oil temperature in oil tank is generally higher than that of oil during rolling. In order to meet the requirements of production process, temperature control system is added to cooling and spraying system to control temperature.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. A633 Grade D carbon-manganese-silicon steel, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve A633 Grade D carbon-manganese-silicon steel work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
