Material: Carbon And Alloy Steel Grade

Dimension: O.D.:6-380mm W.T.:1-35mm L:max12000mm

WT Tolerance: +/-0.15mm

Production Method: Seamless Cold Drawn/Rolling

Delivery Condition: +Cc +LCc +SR +Ad +N NBK

Applications: Hydraulic Cylinder/Oil Cylinder Tube/Excavator Chains and Parts

a: Rm: 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.
d: For calculation purposes the following relations are recommended:
for delivery condition +C: ReH ≥0.8 Rm
for delivery condition +LC: ReH ≥0.7 Rm
For calclulation purposes the following relation is recommended:ReH≥0.5Rm
e: For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimum 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.
