^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
Note: Special steel grade is also available, according to customer request.
