^aRm: tensilestrength; ReH: upper yield strength;A: elongation after fracture
b 1Mpa=1N/mm2
c Depending on the degreeof cold work in the finishing pass the yield strength may nearly be as highas the tensile strength. For calculation purposes the followingrelations are recommended: fordelivery condition +C: ReH ≥0.8Rm fordelivery condition +LC: ReH ≥0.7Rm
d For calclulationpurposes 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 valuesgiven in this Table
f For tubes with outsidediameter>160mm: ReH≥420Mpa
