ARm: tensilestrength; ReH: upper yield strength; A: elongation after fracture
B1Mpa=1N/mm 2
CDepending on the degree of cold work in the finishingpass the yield strength may nearly be as high as the tensile strength.
DFor calculation purposes the following relations are recommended:
For delivery condition +C: ReH≥ 0.8Rm for delivery condition+LC: ReH≥ 0.7Rm
EFor calculation purposes the following relation is recommended: ReH≥0.5Rm
FFor tubes with outside diameter≤ 30mm and wall thickness≤ 3mm the ReH minimum values are 10Mpa lower than thevalues given in this table.
