E470 / 20MnV6 Seamless Steel Pipe for Hydraulic Cylinders High
Tensile Low Alloy Steel Hollow Bar
OVERVIEW
Pneumatic and hydraulic pipe is by precision cold drawn, and then
do the honing or skiving internal pipe. Use in pneumatic machinery,
food machinery, or humid environments easier to rust. To ensure air
hydraulic cylinder’s lifetime, doing plated internal diameter, let
the internal pipe not easy to rust and have a longer service life
of pneumatic and hydraulic cylinders.
E470 & 20MnV6 are similar grades & are high tensile low alloy
carbon manganese steel which are micro alloyed vanadium.
APPLICATIONS
Tubular parts for the automotive, oil and gas, construction,
general engineering and agricultural industry, such as bushes,
hydraulic cylinders, hollow shafts, rings, hollow rolls for
conveyors, nuts, gear wheels, shafts, axles, stuffing boxes,
spindles, drill jigs, rolls etc.
FEATURES
- Dimensional accuracy: cylinder wall thickness deviation, uneven
thickness, diameter deviation, ovality is small.
- Surface quality: through the head, mandrel, furnace temperature
control surface smoothness inside and outside the body, can better
control the tube pitting, scale and other macro-defects, better
meet the requirements of customers scraping rolled cylinder surface
quality requirements .
- Mechanical properties: through the hot-rolling process or heat
treatment process grades of mechanical properties to meet the BS EN
10297-1: 2003 and GB / T8163-2008 standards on the mechanical
properties of the material requirements.
- Others: According to the customer's requirement, the sulfur content
of 0.020% ~ 0.045% can be added to the E470 material to improve the
machining performance of the cylinder tube and reduce the tool
consumption of customers. For large-diameter piston market on the
market, according to customer demand, can provide end-thickening
cylinder tube blank, reduce customer cutting capacity.
