a: Rm: 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.
d: For calculation purposes the following relations are recommended:
for delivery condition +C: ReH ≥0.8 Rm
for delivery condition +LC: ReH ≥0.7 Rm
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.
