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 Applications
As piston rods are very common used in the industry, our products are able to be applied in mining machinery, textile, printing industry, power project, etc.
And piston rods are also using with honed tubes,so in hydraulic systems they can also be applied, like forklift automobiles.
