耐磨板NM450加工(图1)

 NM450是高强度耐磨板。

Nm450 is a high strength wear plate.
命名:N是耐(nai)M是磨(mo)两个中文汉字的第一个拼音字母,450则代表这种钢板的平均布氏硬度
Name: n is Nai, M is the first pinyin letter of Mo, and 450 represents the average Brinell hardness of the steel plate
热处理:高温回火,淬火+回火(调质)
Heat treatment: high temperature tempering, quenching + tempering (quenching and tempering)
应用:NM450耐磨板被广泛应用矿山机械、煤矿机械、环保机械、工程机械等,也常用作为屈服强度≥850MPa高强度结构钢使用。
Application: nm450 wear resistant plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc. it is also commonly used as high strength structural steel with yield strength ≥ 850mpa.
作用:主要是在需要耐磨的场合或部位提供保护,使设备寿命更长,减少维修带来的检修停机,相应的减少资金的投入。
Function: mainly in the need of wear-resistant occasions or parts to provide protection, so that the equipment life is longer, reduce maintenance downtime caused by maintenance, corresponding to reduce capital investment.
性能:屈服在950多,抗拉强度在1180上。
Properties: yield over 950, tensile strength over 1180.
NM450耐磨板对应国外标准及牌号JFE:NK-EH450/HARDOX450/DILLDUR:450V
Nm450 wear resistant plate corresponding to foreign standards and brands JFE:NK-EH450/HARDOX450/DILLDUR :450V
耐磨钢板合金耐磨层和基体之间是冶金结合。通过专用设备,采用自动焊接工艺,将高硬度自保护合金焊丝均匀地焊接在基材上。复合层数一层至两层以至多层,复合过程中由于合金收缩比不同,出现均匀横向裂纹,这是耐磨钢板的显著特点。
The alloy wear-resistant layer of wear-resistant steel plate is metallurgically bonded with the substrate. Through special equipment and automatic welding process, the high hardness self shielded alloy welding wire is evenly welded on the substrate. The number of composite layers is from one to two or even more. Due to the different alloy shrinkage ratio, uniform transverse cracks appear in the process of composite, which is a remarkable feature of wear-resistant steel plate.
