Honed cylinder tube or skived & roller burnished tube is a very important part in cylinder building. honed cylinder tube is known as honed tubing also, it is usually made of cold drawn seamless tubes , as hydraulic cylinder tubes are usually used to manufacture hydraulic cylinders body, so it is called hydraulic cylinder barrel commonly. There are many different steel grades can be used as the material of hydraulic cylinder tubes, and here below are the most popular materials.
Carbon steel ST52, ST52.3,
Carbon steel E355
Carbon steel SAE 1020, Chinese 20#, C20
Steel SAE 4140: also known as 42CrMo or 42CrMo4
Steel 4130 4340 34CrMo4 35CrMo
Stainless steel 304
Stainless steel 316
ST52 honed cylinder tubes
ST52 honed cylinder tubes are honed tubes made of material steel grade ST52, and with standard of DIN 2391. St52 is equal to St52.3. Usually this materials of honed tubes are describled as: cold drawn seamless honed tubes as per DIN2391 /ST52-BKS. BKS standards for the heat treatment for the honed tubing, which is stress relieved heat treatment. Here below is the specification of the steel ST52.
| Grade | Chemistry | % | Yield | Tensile | Elongation | Typical Hardness |
