Good properties of S960QL welding carbon sheet

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 S960QL welding 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.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate S960QL welding has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S960QL welding are higher than that of annealed S960QL welding, but the elimination of internal stress is not as good as annealing. The normalizing operation of S960QL welding is simple, the cost is low, the productivity is high, and it is widely used in actual production.
