SM570 carbon steel plate sheet hot rolled technique

All steel pipes operated by our company are in compliance with national standards, and the original bill of materials of steel mills is attached. At the same time, we supply the SM570 carbon steel plate sheet seamless steel pipe, electrical Resistance Weld pipes, large diameter welded pipes ordering business of various specifications and materials and the railway and road transportation business for the majority of users.

Over the years, the company has established a standard of SM570 carbon steel plate sheet steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to SM570 carbon steel plate sheet quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by SM570 carbon steel plate sheet metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the SM570 carbon steel plate sheet steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

The effect of nitrogen (N) on the properties of SM570 carbon steel plate sheet 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 SM570 carbon steel plate sheet and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
