Introduction to cast low carbon alloy steel bucket tooth
Excavator bucket teeth's life has a close partnership with its overall performance, and its overall performance depends upon the material tissue, therefore the bucket teeth with the material are critical aspects of enhancing the tooth life.
Bucket teeth not only have higher strength and abrasion resistance, also desire to have enough ductility and toughness, lath martensite not merely has high strength and hardness, ductility and toughness are fairly excellent, as tooth material is ideal.
Low alloy wear-resistant steel is usually accomplished by proper heat remedy, receiving higher dislocation of lath martensite, compared with high manganese steel, which reduced the level of alloying components, the production expense is not higher, production test also indicated that low alloy steels have excellent mechanical properties and wear resistance.
Low alloy wear-resistant steel can be obtained by suitable heat remedy with high dislocation of lath martensite, it not just has higher strength, and also has great ductility and toughness. Overcome the must with manganese steel hardening in advance as a way to get high hardness shortcomings.
Having said that, tooth cast low carbon low alloy steel includes a lot of limitations, even more sophisticated casting is tough to escape the presence of casting defects (inclusions, bubbles, shrinkage, piping, and casting grain size inhomogeneity, and so on), even when these defects by subsequent heat treatment is difficult to remove.
