SA573 Gr 70 carbon steel material The company contributes to environmental protection

SA573 Gr 70 carbon steel material,In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments. Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.SA573 Gr 70 carbon steel material

Ordinary medium and thick steel plate is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

Tunisia cutomer purchased around 1500 tons 304L,310S stainless steel plate from us and make tanks in August, 2017. The company was skilled in the design and manufacture of stainless steel tanks, processing systems and equipment for the food, dairy, beverage, chemical, pharmaceutical, biotechnology, and pure water industries. They also sent the inspection team come our company and visited our production line. After using our stainless steel plate, the customer was very satisfied with our products.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

SA573 Gr 70 carbon steel material,On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
