What are rust removal and prevention measures for hardox 450 steel welding process

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and Hardox 450 steel welding process heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported Hardox 450 steel welding process to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Hardox 450 steel welding process, NM400 wear plate is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance. The average hardness of NM400 wear plate is 400HB. After quenching, or quenching and quenching, NM400 wear plate has a good martensite-bainite microstructure. The addition of molybdenum, nickel, and boron alloys ensures uniform texture throughout the thickness direction.

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.

Different from Hardox 450 steel welding process, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
