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
