a. Rm: tensile strength ; ReH: upper yield strength (but see 11.1); A: elongation. For symbols for the delivery condition see Table 1.
b. 1 Mpa = 1 N/mm2
c. Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strengths. 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 calculation purposes the following relations is recommended: ReH ≥0.5 Rm
e. For tubes with outside diameter ≤ 30 mm and wall thickness≤ 3mm, the ReH minimum values are 10 Mpa lower than the values given in this Table.
