EN 10305 - 1 Oil Cylinder Seamless Cold Drawn Tubes For Industry Machinery

Mechanical Propertied At Room Temperature:(Minimum Values for the Delivery Condition)

Rm: tensile strength; ReH: Upper yield strength (but see 11.1); A: elongation after fracture. 

1MPA=1N/mm2
Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as thetensile strength. 

For caculation purposes the following relations are commended:
For delivery condition +C: ReH>=0,8 Rm;For delivery condition +LC: ReH >= 0,7 Rm.
For calculation purposes the following relationship is recommended: ReH >=0,5 Rm
For tubes with outside diameter <=30 mm and wall thickness <=3 mm the ReH minimum values are 10 MPa lower than the values given in this table.
For tubes with outside diameter > 160 mm: Reн >=420 MPa.
