Inspections
In order to guarantee a uniform good quality chemical analysis, destructive testings, metallographic examinations and mechanical testings are performed according to international standards and specifications.
Non-destructive Testing
- Ultrasonic testing (manually and/or by means of automatic shaft/disc testing facilities
- Magnetic crack testing
- Dye penetrant inspection
- Visual testing
- Heat stability testing
- Material mix-up test
Destructive Testing
- Tensile testing (up to 900° Celsius)
- Impact testing (–196° Celsius to 200° Celsius) according to DIN EN 10045-2; ASTM E 23; DIN EN ISO 148-2
- Hardness testing (HB, HV, HRC)
- Bending and folding inspection
- Jominy testing
- Testing for intercrystalline corrosion/pitting corrosion
- Residual stress inspection
- Laboratory heat treatment
Metallographic Inspection
- Micro-section assessment
- Sulphur print
- Macro-etchings
- Blue brittleness inspection
- Mobile metallography
- Measuring of ferrite content and permeability
Chemical Analysis

- Slag analysis
- The following supplementary testings, for example, are provided for by means of contracts with qualified external cooperation partners:
- Long-term trials
- Fracture mechanics
- Fatigue strength
- Electrical and magnetic parameters
- Time-temperature diagrams
- Electron microscopy
- Microanalysis
- Computer simulations
