JIS G3445 STKM13C carbon steel seamless tube is a high-precision steel tube material that is produced through cold drawing or hot rolling. It is primarily used for the production of hydraulic components, such as hydraulic cylinder barrels, Can be seamless tube, due to the characteristics of no oxide layer on the inner and outer walls of the precision steel tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, and so on.
STKM 13C Carbon Steel Seamless Tubes are also known as mild steel pipes and tubes. JIS G 3445 Grade STKM 13C Tubes are low-cost Low Carbon Steel Tubes with max 025% carbon content that are easy to form and shape. These seamless pipes are manufactured as per JIS Specification and commercially referred to as cs pipes or ms pipes. Mechanical characteristics may be bent at any angle without being deformed. It is primarily used to prepare steel pipes in hydraulic systems’ oil circuits, commonly known as hydraulic hard pipes and precision steel pipes for automobiles.
Delivery Condition Of STKM13C Carbon Steel Seamless Tube : BK, BK+S, GBK, NBK
+C (BK) Cold drawn / hard (after the last cold forming no heat treatment)
+SR (BKS) Cold drawn and stress relieved annealed (after the final cold drawing process the tubes are stress relieved annealed in a cotrolled atmosphere)
+A (GBK) Annealed (after the last cold drawing process the tubes are annealed in a controlled atmosphere)
+N (NBK) Normalized (after the last cold drawing process the tubes are normalized in a controlled atmosphere)
Benefits Of JIS G3445 STKM13C carbon steel seamless tube
- Superior surface finish
- High yield strength
- Dimensional accuracy and excellent micro-structure uniformity
- Enhanced machinbility
- High strength to weight ratio
- Tight tolerances, resulting in reduced machine time
- Possible spiraling eccentricity inherent in product
- Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.
- Good weld ability: The weld ability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.
