What are the materials for honed cylinder tubes?

 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.

THE APPLICATION OF DIN2391 ST52.4 PRECISION HYDRAULIC STEEL TUBE

图片
  ST52.4 Hydraulic steel tubes   are tubes made in accordance to DIN 2391 / DIN 2445. ST52.4 is a high grade steel material, it can withstand higher working pressure with same tube OD size compare to ST37.4 material.  The delivery condition for grade ST52.4 tubes are in NBK finishing, which is normalized, phospated, and oiled inside and outside. Hydraulic tubes ST52.4 are measured by Outer Diameter (OD) and in varies tube thickness (THK). Difference of OD and tube thickness lead to different working pressure. ST52.4 Precision Hydraulic tube  is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure stainless steel tubing. In the field, high-pressure tubing is used for down-hole control systems, hydraulic and pneumatic piping, chemical injection modules, vacuum systems, and much more. Chemical/petrochemical:   High press

  Chrome plated OD tubing   is also called chrome plated   hollow bar . Production with internal no honed and external chrome plated tubes, Chrome plated OD tubing usually made from grades ST52 and ST52.3 Drawn Over Mandrel (DOM) steel tubing and  seamless cold drawn tube . Chrome plated tubing is used in numerous types of industrial applications, including: Elevator Cylinder Telescope cylinders Scaling ladders Earthwork machines Agriculture machines And more Wuxi YUTONG  as a professional chrome plated tubing factory, there are various types of hydraulic chrome tube,  chrome plated rod , hollow chrome rods/bars/shafts we have in stocks are standard chrome plating and  induction hardened chrome plating  . Other types of steel rods such as nickel-chrome plated rod and hollow chrome plated bars are also available on request.
