Mechanical testing of F91 forged bars
Scope of testing
For each test unit and each test location, the following tests shall be carried out:
Microsection, longitudinal with photo picture (500:1)
Tensile test at 20°C (±5°) according EN ISO 6892- 1 [9] (test method A)
Hot tensile test according EN ISO 6892-2 [10] at design temperature (±5°) – if no information is indicated, the hot tensile test shall be performed at 350°C (±5°).
Impact test according EN ISO 148- 1 [11] on 3 Charpy V-notch test samples at 20°C (±5°).

The following table shows preliminary reference values for the 1 % creep limit properties and stress rupture properties of F91 forged parts. The values in the following table are average values of all available (scattering range) records. Based on the available records of all long-term tests up to now, it may be expected, that the lower limit of the scattering range, at the assigned temperature , will be 20% under the stated (average-)value.
