The mechanical properties at room temperature shall be as given in the table below:
| Tensile strength (N/mm2): | 320 to 460 |
| Yield strength (N/mm2): | 195 min. |

Flattening Test:The flattening test applies to tubes greater than DN 50. A ring not less than 40mm in length taken from one end of each selected tube shall be flattened cold between parallel flat platens without showing either crack or flaw until the distance between the platens, measured under load, is not greater than 75% of original outside diameter of the tube, and no cracks or flaws in the metal elsewhere than in the weld shall occur until the distance between the platens is less than 60% of original diameter. The weld shall be placed at 90° to the direction of flattening.
Bend Test:Black tubes up to and including DN 50 shall be bent cold without any sign of fracture or failure, through 180° round a former having a radius at the bottom of the groove equal to 6 times the outside diameter of the tube as given in the Table. Hot-dip zinc coated tubes shall be bent cold without cracking of the steel, through 90º round a former having a radius at the bottom of the groove equal to 8 times the outside diameter of the tube.
Hot dipped Galvanized Coating:After the 4 successive one-minute immersions in the copper-sulphate solution, the test sample shall not show any adherent red deposits of metallic copper.
