Cylinder
Specification: Inner Diameter Φ30-60mm with thickness 3-50mm
Material: Precision cold-drawing seamless tubes (20# / 45# steel,16Mn, 27SiMn, 20Mn2)
Standard: GB8713-88

Piston Rod
Diameter:φ5-φ300mm
Materials:45# steel, 2Cr13, 40Cr steel,

Process:
Materials selecting →Tempering →Turning →High-frequency quenching →External grinding
→Hard chrome plating →External grinding
After tempering and surface high-frequency quenching, then surface hard chrome plating, the processes make the cylinder tough inside and hard outside with high surface finish.
