WEAR RESISTANT STEEL PLAT Nm400

WEAR RESISTANT STEEL PLAT nm400

nm400 wear-resistant steel plate refers to the special plate products used under large-area wear conditions, wear-resistant steel plate alloy between the wear-resistant layer and the substrate is a metallurgical combination, the alloy wear-resistant layer is generally 1/3~1/2 of the total thickness. The wear-resistant layer of nm400 wear-resistant plate alloy is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are also added. The carbides in the metallographic structure are distributed like fibers, and the fiber direction is perpendicular to the surface. The microhardness of nm400 steel carbide can reach more than HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good oxidation resistance, and are completely normal for use within 500℃. nm400 wear-resistant steel plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc., and is also commonly used as a high-strength structural steel with yield strength ≥700MPa.

• Fan Wei: Belongs to wear-resistant steel plate (wear-resistant plate) series.
• Name: N is nai (nai)M is the first pinyin letter of the two Chinese characters, and 450 represents the average Brinell hardness of this steel plate
• Heat treatment: high temperature tempering, quenching + tempering (tempering)
• Application: Mainly to provide protection in the need of wear-resistant occasions or parts, so that the equipment life is long, reduce the maintenance and shutdown caused by maintenance, and correspondingly reduce the investment of funds.
• Performance: Yield in more than 800, tensile strength in 1000.
