FERRITE CONTENT AND MAGNETIC PERMEABILITY
The ferrite content evaluated using the Schaeffler diagram, modified by Pryce and Andrews (Figure RMC 1341.2, Section 3, RCC-MR 2007) shall be less than 0.5 %.
The relative magnetic permeability of the finished forgings shall be measured at room temperature after solution annealing. The value measured shall be lower than or equal to 1.03 for fields of over 80000A/m (1000Oe) as per Test method 2 or measured with a low μ permeability indicator as per method 3 of ASTM A342.
One specimen per lot shall be taken from a position close to mechanical test specimens.
Measurements made with other physical methods (e.g. permascope, magnetoscope, etc.) can be accepted provided information is supplied about the type and trade mark of apparatus proposed and information about the calibration. For these methods 1 test will be required per forging.
STRUCTURE
A micrographic examination, with photographs, shall be performed parallel to the main direction of extension. The structure must be homogeneous.
(1) Grain size
The grain size number determined in accordance with EN ISO 643 shall be equal or greater than 3. The determination is performed on test samples taken from the immediate vicinity of the mechanical test specimens.
(2) Non-metallic inclusions
Amount and definition shall meet the requirements of the ITER Vacuum Handbook; definitions shall meet the standard ASTM E45-10: Microinclusions (indigenous inclusions detectable by microscopical test methods): method D is applicable of ASTM E45-10. Severity level number shall be at most 1 for inclusions types A, B and C and at most 1.5 for D.
DELIVERY CONDITION
In the solution heat treated condition and machined to the as-delivered profile.

PENETRATION EXAMINATION
100% liquid penetrant inspection of each forging shall be undertaken in accordance with the requirements of EN 10228-2. The use of an ITER approved liquid penetrant is mandatory as specified in in the ITER Vacuum Handbook.
VOLUMETRIC EXAMINATION
100% of ultrasonic inspection of each product shall be provided in accordance with EN 10228: Part 4. The acceptance criteria, which depend on the thickness, shall be those defined in the standard EN 10228-4. The quality class 3 is adopted for forgings used for structural application.
This examination shall be performed when the profile of the part permits satisfactory test performance. It shall be performed in the following order of preference:
- after final machining
- after heat treatment for mechanical properties, whether subsequent machining is performed or not.
The entire volume of the part shall be subject to ultrasonic examination. 100% scanning coverage defined in §12.4 of standard EN 10228-4 shall be performed.
The ranges considered and the acceptance criteria which depends on the thickness of the part examined, shall be those defined by the standard EN 10228-4 for normal probe.
COMPETITIVE ADVANTAGE:
(1) More than 50 years experience of research and develop in high temperature alloy, corrosion resistance alloy, precision alloy, refractory alloy, rare metal and precious metal material and products.
