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.
Our Advantages
1. Experienced manufacture for piston rods and hydraulic systems for over 10 years.
2. Complete manufacturing facilities including the work:grinding, straightening, milling and drilling,etc.
3. Raw materials are ordered from famous supplier, as:TPCO, BAO STEEL, SHA STEEL.
4. Strict testing procedures.
5. Packing safely:we spread anti-rust oil on our products before shipping, plastic caps on tube ends to protect inside surface, all rods will be protected with cardboard tube., and will be packed with seaworthy package or in wooden case.
