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
d For calclulation purposes the following relation is
recommended:ReH≥0.5Rm
e For tubes with outside diameter ≤30mm and wall thickness ≤3mm the
ReH minimum values are 10Mpa lower than the values given in this
Table
f For tubes with outside diameter＞160mm: ReH≥420Mpa
Note: Special steel grade is also available, according to customer request.
