Elongation
| Elongation: | portrait | horizontal |
| Minimum values for standard circular specimens or small scale specimens with a gauge length of 4D | twenty two | 14 |
| Rectangular specimens with a wall thickness of 5/16 in. (7.94 mm) and above, and all small-sized specimens tested in full section, with a gauge length of 2 in. (50 mm) | 30 | 20 |
| Rectangular specimens with wall thickness up to 5/16 in. (7.94mm), gauge length 2in. (50mm) (1/2in. wide, 12.7mm) | A | A |
A Allowed from the elongation value listed above, for wall thickness below 5/16in. (7.94mm), for every 1/32in. (0.79mm) thinner, the longitudinal elongation is reduced by 1.5% and the transverse elongation Decrease by 1.0%. The table below gives the minimum values for different wall thicknesses.
| wall thickness | WPB |
| in. | [mm] | portrait | horizontal |
| 5⁄16 (0.312) | 7.94 | 30 | 20 |
| 9⁄32 (0.281) | 7.14 | 28.5 | 19 |

The table above lists the minimum elongation per 1⁄32 in. [0.79 mm] reduction in wall thickness. When the wall thickness is between the above two values, the value of the minimum elongation is determined by the following formula:
| experimental method | formula |
| portrait | E= 48t + 15.00 |
| horizontal | E = 32t + 10.00 |
E = Elongation at 2 in. or [50 mm] gauge length, %,
t = actual thickness of the specimen, in. [mm].
Hardness: ≤197 HB
heat treatment:
1. WP11 fittings should be delivered at annealed, fully annealed or normalized plus tempered temperature. When normalizing and tempering are adopted, the minimum tempering temperature shall not be lower than 620°C.
