Effect of cooling process on microstructure and properties of EN steel grade S420NL material

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, EN steel grade S420NL material Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach EN steel grade S420NL material 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual EN steel grade S420NL material production capacity: 3.5 million tons."

The wear-resistant layer of EN steel grade S420NL material wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN steel grade S420NL material carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Expect in the EN steel grade S420NL material goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen EN steel grade S420NL material product development technology, excellent production team, hand strict quality control, sales and after-sales service.
