SM400A/B/C steel structural quality carbon steel profiles, A572 grade 50 high strength steel plates and bars used for riveting, bolting or welding of bridges and buildings and general structural purposes.
Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business A572 grade 50 high strength steel department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and A572 grade 50 high strength steel after-sales service department constitute the service customer network.
In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This A572 grade 50 high strength steel production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate A572 grade 50 high strength steel size.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as A572 grade 50 high strength steel. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
