Rm: tensile strength; ReH: Upper yield strength (but see 11.1); A: elongation after fracture.
1MPA=1N/mm2
Depending on the degree of cold work in the finishing pass the
yield strength may nearly be as high as thetensile strength.
For caculation purposes the following relations are commended:
For delivery condition +C: ReH>=0,8 Rm;For delivery condition
+LC: ReH >= 0,7 Rm.
For calculation purposes the following relationship is recommended:
ReH >=0,5 Rm
For tubes with outside diameter <=30 mm and wall thickness
<=3 mm the ReH minimum values are 10 MPa lower than the values
given in this table.
For tubes with outside diameter > 160 mm: Reн >=420 MPa.
Delivery Conditions
| Designaion | Symbol | Description |
| Cold drawn/hard | +C | No heat treatment after the final cold drawing process. |
| Cold drawn/soft | +LC | After the final heat treatment there is a suitable drawing pass. |
| Cold drawn and stress relieved | +SR | After the final cold drawing process there is a stress relief heat treatment in a controlled atmosphere. |
| Annealed | +A | After the final cold drawing process the tubes are annealed in a controlled atmosphere. |
| Normalized | +N | After the final cold drawing operation the tubes are normalized in a controlled atmosphere. |
Surface Condition:
Ferritic alloy cold-finished steel tubes shallbe free of scale and
suitable for inspection.A slight amount of oxidationis not
considered scale.
Ferritic alloy hot-finished steel tubes shall be free of loose
scale and suitable for inspection.
Stainless steel tubes shall be pickled free of scale.When bright
annealing is used, pickling is not necessary.
Any special finish requirement shall be subject to agreement between the supplier and the purchaser.
