The S420ML material material elongation

The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of S420ML material pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and S420ML material special properties such as good formability, weldability and adaptability to welding process.

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality S420ML material products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel S420ML material, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's S420ML material steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole S420ML material steel transportation industry.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of S420ML material, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

Welcome to our company to purchase, our products are exported to all parts of the world every month, the quality is guaranteed, the S420ML material price is very preferential. Therefore, it has won great trust and praise from customers. Every month, it needs to purchase some steel plates, steel pipes and other major products. If you have any need, please contact us in time!
