The basic principle of nm400 anti-abrasive steel plate, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters "resistant" and "grind" for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.
The advantages of nm400 anti-abrasive steel plate, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
The market mentality tended to be cautious, and the market prices in most regions were adjusted in a narrow range. In terms of resources, the current market inventory continues to digest, but due to the high output of nm400 anti-abrasive steel plate, and the off-season effect of downstream demand is still continuing, resulting in a slow de stocking speed. In the short term, in the case of poor shipment of high price resources and cautious market mentality, it is expected that the price of nm400 anti-abrasive steel plate in the short term may be in weak consolidation operation.
