There are mainly two kinds of wear-resisting steel plate on the
market, one is wear-resisting composite steel plate, the other is
heat treatment wear-resisting steel plate, such as Wuyang Steel Sun
Xiaofan has this kind of steel plate. Wear-resistant steel plate:
NM400, NM450, NM500; 400, 450 and 500 are made by Swedish Steel.
How to choose these two kinds of wear-resistant steel plate, need
to understand the difference between the two kinds of steel plate,
the following comparison from several aspects:
Wear resistance mechanism and wear resistance, Wuyang Iron and
Steel Sun Xiaofan
The wear-resisting layer of the wear-resisting composite steel plate is high alloy composition, and there are a lot of high hardness alloy carbide (ABOUT HV1600) embedded in the matrix in the metallographic structure, and the main anti-wear effect is carbide. The actual micro hardness of wear-resisting layer is much higher than the macro hardness determined, and its strengthening way is the same as hard alloy. Although wear-resisting layer hardness is very high, but can carry the strength is very low, in addition, the substrate is ordinary steel plate, does not have wear-resisting performance.
Heat treatment wear-resisting steel plate is the whole quenching hardening, the whole body has wear resistance, metallographic organization is mainly martensite, so that the overall hardness and strength has been greatly improved, micro hardness and macro hardness are basically the same.
What is the difference between wear-resisting steel plate and wear-resisting composite steel plate? Wear-resisting steel plate and ordinary steel plate difference?
Wear-resisting steel is the general name of iron and steel material with strong wear-resisting performance. Wear-resisting steel is one of the most used wear-resisting materials nowadays. There are many ways to classify wear. According to the wear mechanism, it can be divided into abrasive wear, adhesive wear, corrosion wear, erosion wear, contact fatigue wear, impact wear, fretting wear and other categories. According to different usage scenarios of wear, wear resistant steel is different, such as sliding friction, impact resistant car bucket is a kind of dump trucks, high speed for a long time of rotating shaft and the bearing is a kind of wear-resisting, of course, other types of wear resistant steel, today we introduce mainly used to dump mine car and scraper conveyor of coal mine construction machinery use wear resistant steel. Some people ask, is abrasion very important? Take a simple example, just take the scraper conveyor used in the coal mine as an example, the loss caused by the wear of the middle trough is 100 ~ 200 million yuan per year.
