Manufacturing Process for Square and Flat Bars
The square/flat bars are made from ingots and are processed after giving required reduction ratio and discarding hot top and bottom for homogeneity. They are either processed by hot rolling or hot forging. These bars are further heat treated as per customer requirements by anyone of the following processes
- Annealing
- Normalizing
- Stress Relieving
- Quenching and Tempering
- Spheroidizing Annealing
They are also offered in bright condition by
- Cold drawing (for upto 75x35mm)
They are also offered in
- Cut to length
- Multiple lengths
Quality Check of Square and Flat Bars
Following checks are conducted in bars and reported in the TEST CERTIFICATE as per customer requirement
- Surface inspection (Magnetic Particle Inspection) is carried out of each bar end to end
- Positive Material Identification using XRF to certify in process chemistry of each bar
- 100% dimensional verification using calibrated verniers and Go No-Go gauges
- Step down testing
- Upset forging test
- NMIR (Non metallic inclusion rating)
- Macrostructure testing
- Microstructure phase analysis
- Grain Size
- Ultrasonic Testing for internal defects
- Radioactivity test
- Gas analysis (O, N, H)
