In-House Testing in Austria
We test the chemical composition, relative magnetic permeability and fatigue strength for each melt.
In addition, we carry out various examinations and tests on each rod:
- Tensile test
- Notched bar impact test
- Hardness test
- Acid test (as per ASTM A 262 – Practice A)
- 100 % volumetric ultrasonic NDT
- 100 % volumetric hot spot test
