Characteristic:

1.Abrasion resistance: 

              20 - 25 times of low carbon steel, 

                 8 times of high manganese steel or stainless steel,

                 1.5 times of regular high-carbon and high chromium steel.

2.Temperature resistant: regular type < 60°C; high temperature type <1000°C.

3.Impact resistance: wear resistant layer and the base layer are completely metallurgical b    -onding, afford strong impact, and do not have to worry about shedding. 

4.Processibility: welding, cutting, curling, punching.
