The current research work is to add certain elements boron steel in chrome on the basis of carried out . Our current study found that a certain amount of boron can get a better performance of the Fe-CB alloy composite wear plate . But the factors that influence its alloy microstructure and properties need to be further investigated . This paper examines the different carbon , boron content and heat treatment process for the organization and performance of law . The study found : the carbon content is mainly determined by the number of toughness and alloy carbides , borides and the type , quantity and alloy hardness depends mainly on the boron content . Since boron is added , although cast Fe-CB alloy carbon content in the lower range, but its wear-resistant composite panels have solidified structure essentially different from ordinary carbon steel , www.custom-drawstring-bags.com custom-drawstring-bags.com
