Surface Harden Technique Forged Steel Round Bars Brushed Polished 5.8m-12m

Surface Harden Technique Brushed Polished 5.8-12m Forged Steel Round Bars

Specifications:

Round steel is divided into hot rolling, forging and cold drawing. Hot rolled round bars are available in sizes from 5.5 to 250 mm. Among them: small round steels of 5.5-25 mm are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steels larger than 25 mm are mainly used for manufacturing tube parts of mechanical parts and seamless steel tubes etc.

High strength, hardenability, good toughness, small deformation in quenching, high temperature creep strength and lasting
strength.It is used for manufacturing forgings with higher strength and larger quenched and tempered cross section than 35CrMo steel, such as big gear for locomotive traction, supercharger drive gear, rear axle, connecting rod and spring clamp with great load, and also for drilling pipe joint and fishing tool for oil deep Wells below 2000m.
