LEN10305-1 Precision Steel Tube , Hydraulic Cylinder Tubing cutting to Specified Length
Torich produce seamless pecision steel tubing for over 20 years.mainly exported to EU USA Asia ect .Keep stock in our warehouse
for various sizes, with good quality.Surface could do glav ect coating .
Bright annealing steel tubing mainly used for Automobile and motorcycle parts, shock absorbers, bearing sets, furniture parts,
hydraulic and pneumatic cylinders, motor casings, fitness equipment, plastic machinery, hydraulic machinery, metal processing,
military, diesel engines, air compressors, petrochemicals, aerospace, Air conditioning, hardware factories and other machinery
industries and all walks of life. Widely used. The promotion and application of precision seamless pipes can save steel, improve
processing efficiency, reduce processing procedures or equipment investment, save costs and greatly save machining hours,
improve production capacity and material utilization, and at the same time help improve product quality and reduce costs.
Economic benefits are important.

aRm: tensile strength; ReH: upper yield strength; A: elongation after fracture
b 1Mpa=1N/mm2
c Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strength.
For calculation purposes the following relations are recommended:
for delivery condition +C: ReH ≥0.8 Rm
for delivery condition +LC: ReH ≥0.7 Rm
d For calclulation purposes the following relation is recommended:ReH≥0.5Rm
e For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimim values are 10Mpa lower than the values given in this Table
f For tubes with outside diameter>160mm: ReH≥420Mpa
Note: Special steel grade is also available, according to customer request.
Bright steel pipe is a kind of steel pipe that has been refined by cold drawing or cold rolling, non-oxidative bright heat treatment
(NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and washed with high
pressure, the anti-rust oil on the steel pipe is used for anti-rust treatment, and both ends are sealed. Cover for dust-proof treatment.
