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.
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
Applications: for Auto industry/for machinery use/Oil Cylinder Tube/Motorcyle shock absorber Auto shock absorber innder cylinder/Telescopic Cylinders
Size range: O.D.:6-280mm W.T.:1-30mm L:max12000mm
Note: Special steel grade is also available, according to customer
request.
