Features
High strength with hardenability and good toughness, less deformation while quenching, high creeping strength and persistent strength while the temperature is high. Using for manufacturing the forgings which requires more strength than 35CrMo steel and larger tempering cross-section.
Product Application
42Crmo guide bar is a kind of ultra high strength steel, it is widely used in the industry for its hardenability and toughness.
