Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the St52-3, SM570, SA572 mild steel steel mechanical property requirements are more strict, especially for impact toughness And the aging sensitivity is required to be small The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting The structure should be uniform The grain size should be controlled in 3-7 grades The defects such as interlayer, shrinkage, porosity and porosity should be minimized,St52-3, SM570, SA572 mild steel.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services,St52-3, SM570, SA572 mild steel.
St52-3, SM570, SA572 mild steel,Since its establishment, the company has participated in several key railway and highway projects.
