The developing history of white cast iron can be divided into three stages

hits:1125    date:2018-10-09

As one kind of wear resistance materials, professional liebherr excavator lock pins production supplier said the total developing history for white cast iron can be divided into three stages, such as the common white cast iron, the nickle hardened white cast iron and the high chrome white cast iron, all of them can be used to manufacturing into the finished liebherr excavator lock pins products, which maintain the excellent wear resistance performance, but worse tenacity property, so their mainly application conditions must be the small impact force condition or small hardenedsubstances excavate works, etc.

Professional liebherr excavator lock pins production suppliers said the total carbon element content for these constant temperature quenching common white cast iron bucket tooth is range from 2.21 percent to 2.4 percent, and its silicon element content is only 0.28 to 0.3 percent; the manganese element content is range from 0.69 to 0.71 percent, so because of the low steel percent, professional liebherr excavator lock pins production supplier said the impact tenacity property for finished white cast iron bucket tooth is only 2.1 to 2.54 for each square centimeters, and the harden degree is range from 55 to 59HRC.

 

Prev:The best casting technology scale for excavator bucket tooth inner cavity must be zone or minus
Next:The common chrome element content in high chrome casting iron is equal or beyond fifteen percent
