At the same time, the company operates a variety of products of related iron and S355NL carbon steel plate sheet steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained S355NL carbon steel plate sheet ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S355NL carbon steel plate sheet high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S355NL carbon steel plate sheet wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S355NL carbon steel plate sheet.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, S355NL carbon steel plate sheet deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
