Tool Steel Bars
MMC supplies the best tool Steel Bars for a multitude of applications like press forging , extrusion etc.
Manufacturing Process for Tool Steel
Tool steel is made from ingots by hot rolling/hot forging are processed after giving required reduction ratio and discarding hot top and bottom for homogeneity. These bars are further heat treated by
- Spheroidizing Annealing
- Stress Relieving
- Quenching and Tempering
They are also offered in bright condition by
- Peeling and Reeling (for upto 120mm for rolled)
- Proof machining (greater than 120mm)
They are also offered in
- Cut to length
- Multiple lengths
Quality Check of Tool Steel
Following checks are conducted in tool steel 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 Vernier’s and Go No-Go gauges
- Step down testing
- Upset forging test
- NMIR (Nonmetallic inclusion rating)
- Macrostructure testing
- Microstructure phase analysis
- Grain Size
- Ultrasonic Testing for internal defects
- Radioactivity test
- Gas analysis (O, N, H)
