NM400报价

  NM400耐磨板是高强度耐磨钢板,其具有较高的抗磨损能力。

Nm400 wear-resistant plate is a high-strength wear-resistant steel plate with high wear resistance.
命名:N是"耐磨"中"耐"的第一个拼音字母.
Name: n is the first pinyin letter of "Nai" in "wearable"
M是"耐磨"中"磨"的第一个拼音字母.
M is the first pinyin letter of "Mo" in "wear resistant"
400是布氏硬度值HB值。(400硬度值是广义的,国产NM400硬度值是在400左右。)
400 is the Brinell hardness value Hb. (the hardness value of nm400 is generalized, and the hardness value of nm400 made in China is about 400. )
合金耐磨层的化学成分中碳含量达4~5%,铬含量高达25~30%,其金相组织中Cr7C3碳化物的体积分数达到50%以上,宏观硬度为HRC56~62,碳化铬的硬度为HV1400~1800。由于碳化物成于磨损方向相垂直分布,即使与NM400耐磨板同成分和硬度的铸造合金相比较,耐磨性能提高一倍以上。与几种典型的材料耐磨性对比如下:
The volume fraction of Cr in the carbide layer of HVC 3 is 25 ~ 1400 5%, and the chemical content of Cr in the carbide layer of HVC 3 is more than 25%. Because the carbides are vertically distributed in the wear direction, the wear resistance of nm400 wear-resistant plate is more than doubled compared with the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows
(1)与低碳钢;20~25:1
(1) And low carbon steel; 20-25:1
(2)与铸态高铬铸铁;1.5~2.5:1
(2) 5 ~ 2. 5:1
NM400耐磨板是高强度耐磨钢板,其具有较高的抗磨损能力,布氏硬度值达到400(HBW)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和停机,相应的减少资金的投入。
Nm400 wear-resistant plate is a high-strength wear-resistant steel plate, which has high anti-wear ability. The Brinell hardness value of 400 (HBW) is mainly to provide protection in the occasions or parts that need wear-resistant, so as to prolong the service life of the equipment, reduce the maintenance and shutdown caused by maintenance, and correspondingly reduce the investment of funds.
NM400耐磨板具有很高耐磨性能和较好冲击性能好,能够进行切割、弯曲、焊接等,可采取焊接、塞焊、螺栓连接等方式与其他结构进行连接,在维修现场过程中具有省时、方便等特点,广泛应用于冶金、煤炭、水泥、电力、玻璃、矿山、建材、砖瓦等行业,与其他材料相比,有很高的性价比,已经受到越来越多行业和厂家的青睐。
Nm400 wear resistant plate has high wear resistance and good impact performance. It can be cut, bent and welded. It can be connected with other structures by welding, plug welding and bolt connection. It is time-saving and convenient in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile and other industries Compared with materials, it has high cost performance, and has been favored by more and more industries and manufacturers.
