In production and operation, the company always attaches great importance to product EN10025-4 steel quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market EN10025-4 steel. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

Heat-resistant steel has good oxidation resistance, corrosion resistance and tissue stability. The thermal strength performance is high, and the EN10025-4 steel process performance is good. Heat-resistant steel plates and sheets are commonly used in the manufacture of parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and aviation and petrochemical industries.

Wear-resistant plates are very easy to understand from the literal. They are steel plates designed for large-area wear conditions. Because of its outstanding wear resistance, wear plates have their own unique uses, such as mining machinery and equipment. Ore processing, transportation of ore, ore and equipment often produce severe friction. EN10025-4 steel, General steel plates cannot be subjected to friction for a long time and are easily damaged. Wear plates are very effective in solving this problem.

According to the hardness from HB400 to 600, wear-resistant plates can be divided into NM400, NM450, NM500, NM550, NM600 and so on. Because of its toughness, the wear plate can accept impact, sensation, bump, scratch and prick day after day. With its good processing performance, wear-resistant plate, EN10025-4 steel can be bent, formed and welded, and can prevent the occurrence and propagation of cracks, which is also the reason why wear-resistant plate can be used as structural steel.

EN10025-4 steel, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of EN10025-4 steel and No. 20 steel is 7.85kg/cm3

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate EN10025-4 steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel EN10025-4 steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
