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
