Other information

Cylinder tube size and choice
According to the cylinder pressure and inside diameter size, different steel tube Would be chosen.
1. ID ≤300mm, cold rolled precision seamless tube would be choose
2. 300mm≤ID ≤500mm, hot rolled seamless tube would be choose
3. 500mm≤ID ≤1000mm, forged tube would be chosen

4. Cylinder tube steel grade: SAE1020, SAE1045 ,27SiMn, S355JR, S355J2G3 St52-3, SUS304, SUS316L etc .
5. Cylinder tube inside boring and honing, roughness R0.2-R0.3,
6. Cylinder tube inside chromating: if necessary, tube inside cremating could be applied.

Piston rod is a very important part for hydraulic cylinder.
1. Piston rod steel grade: SAE1045, 42CrMo4, SUS410, SUS420, SUS304, SUS316L
2. Piston rod cremating and surface hardness.
DALLAST company ensure that every piece piston rod would be surface hardened before cremating, surface hardness is HRC55~60, Chromating film thickness is 0.03~0.04mm if there are no other specific requirements.

Painting and storage.
After hydraulic cylinder pass through pressure test, painting is necessary.
