EN10305-1 Seamless Round Hydraulic Cylinder Tubing

Hydraulic Cylinders Tubes Production Method:

Seamless Cold Drawn/Rolling Shap: Round

EN10305-1 Seamless Tubing Applications:

Hydrulic Cylinders/Oil Cylinder Tube/Excavator Chains And Parts

EN10305-1 Seamless Tubing Delivery Condition: +Cc +LCc +SR +Ad +N NBK

EN10305-1 Seamless Tubing Size range:

O.D.:6-380mm

W.T.:1-35mm

L: max12000mm

Steel Grade and Chemical Compositions:

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
