QS wear-resistant composite of high wear-resistance determines its cost-effective. Taking the steel liner of the steel industry as an example, most of the unloader car linings of a lot of units use a 20mm thick 16Mn board, and the service life is basically within 2 months at a cost of about 650 yuan / square meter. With our 8 + 6 (8mm 6mm wear-resistant layer on the substrate surfacing wear) wear-resistant steel, we promise is 20mm 16Mn board life of 10 times the price of about 3,000 yuan / square meter. Based on the above data, we have been able to save nearly 50% of our operating costs on a purely cost basis. This does not include maintenance and repair costs, safety hazards and production losses that result from frequent liner replacement.
