Optifine is a highly efficient and potent grain refiner based on a Titanium and Boron composition, made in the form of rods and coils. The diameter is 9mm and the standard coil weighs 180kg, with 250kg coils also available.
Optifine looks just like all other standard grain refiner; is completely interchangeable and can be used on all alloy grades and production processes. The difference is that you will add only 70% of what you would for a standard grain refiner, and you would spend only HALF what you would purchasing standard grain refiner.
