Steel Grade and Chemical Compositions:

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 minimim 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.
