In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel A514 Gr B alloy steel plate surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A514 Gr B alloy steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A514 Gr B alloy steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
The steel such as A514 Gr B alloy steel plate delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
Since the beginning of this year, the global A514 Gr B alloy steel plate steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global A514 Gr B alloy steel plate steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
