Apart from above, Our Material has the following properties.
1. It gives 2.5 times more strong Compared to the similar form in flake graphite.
2. It gives good machining qualities and has fine finishing.
3. It have excellent weld ability
4. It has good wear resistance quality.
5. It has good corrosion resistance.
Advantages when used for Sugar Mill Rollers:
It has higher strength and higher hardness give more life because of reduced wear.
It has less breakage because of higher strengths and elongation quality (elongation is kept at lower side at just safe level to avoid ill effect of high elongation.)
Material with 3 fold strength minimizes the teeth breakage in Messchaert grooves which is very vulnerable.
