Ferro Columbium

1.Composition:Fe,Nb+Ta,Ta,Al,Si,C,S,P,W,Mn,Sn,Pb,As,Sb,Bi,Ti

2.Brand:FeNb70,FeNb60-A

3.Material:Ferroniobium concentrate

Properties: Ferro Columbium alloy is applied to steel making and foundry as additive. We add niobium to stainless and heat resistant steel so as to raise its plasticity and corrosion resistance of your product. We add niobium to structural steel to improve welding property of the structural steel and enhance its strength and plasticity to prevent welding seam from corrosion. Niobium is indispensable to high temperature steel and alloy, since niobium can enhance high temperature strength, refine grain and avoid grain growth. Carbide which is made by Niobium is combined with carbon can eliminate harmful effects that chromium carbide deposits in stainless steel to enhance abrasion resistance of steel.

4.Chemical Compositions(GB/T7737-1997)

5.Package:100kg per iron bucket
