Ferro boron
1. Application:ferro boron is applied to iron making, foundry and used as boron element additive in other applications.
2. Properties: The most important function of Boron is we just need ultra low volume of boron to improve hardenability obviously to replace a great deal of alloy element. In addition, it can improve mechanical properties of your product, cold deformation, welding properties and high temperature properties etc.
3. Chemical Compositions(GB/T5682-1995)
4. Shape:ferro boron should be delivered in powder.
5. Size: Its size range is from 5 to 100mm. The total quality of the product whose particle size range is more than 100mm and less than 5mm should not exceed 5% of the total quality of the batch.
6. Package:1Metric Ton per big bag (polypropylene knitted bag) or 100kg per iron bucket.
