An Rm: tensile strength; ReH: upper yield strength; A: elongation
after fracture
B 1Mpa=1N/mm 2
C Depending on the degree of cold work in the finishing pass the
yield strength may nearly be as high as the tensile strength.
D For calculation purposes the following relations are recommended:
For delivery condition +C: ReH≥ 0.8Rm for delivery condition +LC:
ReH≥ 0.7Rm
E For calculation purposes the following relation is recommended:
ReH≥ 0.5Rm
F For tubes with an outside diameter≤ 30mm and wall thickness≤ 3mm
the ReH minimum values are 10Mpa lower than the values given in
this table.
