The gas cylinder steel coil and sheets are our main products. Our main conducted standards for gas cylinder steel coil and sheets are JIS G3116, GB6653, EN10120. The typical gas cylinder steel grades are SG255, SG295, SG325, HP265, HP295, HP325, P245NB, P265NB, P310NB, P355NB, etc. For the gas cylinder steel coil S460Q steel material, we provide slitting, cutting, and stamping service. So as to meet different size and shape requirements of the customers. The gas cylinder steel coil and sheets are mainly used to make gas cylinders.Since it was established in 2000. Based on the domestic rich S460Q steel material product resources and the great steel demand of the international market, our S460Q steel material service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel productsAdvantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the S460Q steel material steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.The effect of nitrogen (N) on the properties of S460Q steel material and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in S460Q steel material and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
