| Abstract: | A kind of new M-B low-alloy wear resistance steel w ith high strength has been studied to overcome the deficiency of traditional high-manganese steel used in m aking grippad. Combined reasonably selected composition and proper heat-treatment process, this kind of steel possesses high strength, hardness and toughness. At the same time, its synthetic property is very well. Because of the Nickel addition, its low-temperature fragility is improved. Therefore, grippad made of this steel is more suitable to work in low-temperature areas than those are made of the other alloys. |
