雙金屬復(fù)層nm400耐磨板是專供大面積磨損工況使用的板材產(chǎn)品，是在韌性、塑性很好的普通低碳鋼或者低合金鋼表面通過堆焊方法復(fù)合一定厚度的硬度較高、耐磨性優(yōu)良的耐磨層而制成的板材產(chǎn)品。

Clad nm400 wear-resistant plate is used for large area wear plate products operation, the toughness, plasticity is good ordinary low-carbon steel or low-alloy steel surface by excellent wear-resisting layer surfacing method of composite thickness with high hardness, wear resistance and made of sheet metal products.

雙金屬復(fù)合耐磨鋼板由低碳鋼板和合金耐磨層兩部分組成，抗磨層一般占總厚度的1/3－1/2。工作時(shí)由基體提供抵抗外力的強(qiáng)度、韌性和塑性等綜合性能，由耐磨層提供滿足指定工況需求的耐磨性能。

Double metal composite wear-resistant plate made of low carbon steel and alloy wear resistant layer is composed of two parts, the general wear layer of total thickness 1 / 31 / 2. In the work, the strength, toughness and plasticity of the matrix are provided by the matrix, and the wear resistant layer is provided to meet the requirements of the specified working conditions.

nm400耐磨鋼板合金耐磨層和基體之間是冶金結(jié)合。通過專用設(shè)備，采用自動(dòng)焊接工藝，將高硬度自保護(hù)合金焊絲均勻地焊接在基材上，復(fù)合層數(shù)一層至兩層以至多層，復(fù)合過程中由于合金收縮比不同，出現(xiàn)均勻橫向裂紋，這是耐磨鋼板的顯著特點(diǎn)。

Metallurgical bonding between wear resistant layer and matrix of nm400 wear-resistant steel plate alloy. Through special equipment, automatic welding process, the high hardness of self protection alloy wire is uniformly welded on the substrate, composite layers one layer to two layers or multilayer, composite process because of different alloy contraction ratio, uniform transverse crack, this is a significant characteristic of wear resistant steel plate.

nm400耐磨板耐磨層主要以鉻合金為主，同時(shí)還添加錳、鉬、鈮、鎳等其它合金成份，金相組織中碳化物呈纖維狀分布，纖維方向與表面垂直。碳化物顯微硬度可以達(dá)到HV1700-2000以上，表面硬度可達(dá)到HRc58-62。合金碳化物在高溫下有很強(qiáng)的穩(wěn)定性，保持較高的硬度，同時(shí)還具有很好的抗氧化性能，在500℃以內(nèi)完全正常使用。

The wear resistance of nm400 wear resistant layer is mainly based on chromium alloy, and also the other alloy elements such as manganese, molybdenum, niobium, nickel and other alloys. Carbide micro hardness can reach HV1700-2000 above, the surface hardness can reach HRc58-62. Alloy carbide has a strong stability at high temperature, maintain a high hardness, but also has a very good antioxidant properties, in the normal use of 500.
