FeTi / FeB
FeTi 30/40/70 and FeB 15-20% powders, cored-wire fill grades, certified gas content. Stainless stabilization, IF steel, boron hardenability. Mill qualification support.
QUICK ANSWER
Ferrotitanium (FeTi 30-70% Ti) and ferroboron (FeB 15-20% B) powders are master-alloy additions milled to 45-250 µm for dosing titanium and boron into steel and cast iron. Titanium fixes nitrogen and carbon (stabilized stainless and IF steels, grain refinement), while boron at just 0.0005-0.003 percent dramatically increases steel hardenability — two of the most cost-effective alloying levers in steelmaking.
These master alloys exist because adding pure titanium or boron directly is impractical — titanium burns off, boron oxidizes — so they are delivered as iron alloys that dissolve controllably in the melt. FeTi serves stainless steel stabilization (preventing intergranular corrosion in 321/347 grades), interstitial-free automotive steel production, and weld-metal refinement. FeB serves the hardenability trick that lets plain-carbon steels replace expensive alloy steels in automotive and machinery parts. Powder and cored-wire-feedstock forms allow precise, high-yield additions that lump alloys cannot match.
MATERIAL DATA
Lot-level controls focus on the chemistry, particle characteristics, and process values that influence manufacturing consistency and finished-part performance.
| Element | Content | Performance Role |
|---|---|---|
| Titanium (FeTi) / Boron (FeB) | 30-70% Ti / 15-20% B | The active alloying elements in iron carrier matrix |
| Aluminum (Al) | < 5% (FeTi grade dependent) | Residual from aluminothermic production |
| Silicon (Si) | < 4 wt% | Impurity limit for steel cleanliness |
| Carbon (C) | < 0.1-0.5 wt% | Grade-dependent limits |
| Nitrogen + Oxygen | Certified | Gas content affects addition yield |
Final limits can be aligned with the agreed purchase specification.
APPLICATIONS
Steel mills are the core market: FeTi additions stabilize stainless steel (tying up carbon and nitrogen as TiC/TiN to prevent sensitization), produce interstitial-free steels for deep-drawn automotive panels, and refine weld metal microstructure in high-strength steels. The trend to cored-wire injection — where FeTi or FeB powder fills steel sheath wire injected deep into the ladle — has shifted demand toward powder form because wire feeding achieves titanium yields of 60-90 percent versus 30-50 percent for lump additions, directly cutting alloy cost per tonne of steel.
Foundries and welding form the second market: cast iron producers use FeTi for carbide control and FeB for wear-resistant alloy irons; hardfacing and welding consumable manufacturers dose titanium and boron through powder additions to electrode coatings and flux formulations. The welding market in particular buys fine, certified-chemistry powders where batch consistency directly determines weld deposit chemistry and mechanical properties.

Boron only boosts hardenability as free boron — it binds to nitrogen as useless BN. A titanium addition first fixes the nitrogen as TiN, freeing the boron to work. Mills therefore add FeTi before FeB; we supply matched FeTiN products that combine both functions.
FeTi70 with low aluminum for premium stainless; FeTi40 for cost-driven grades. The key certified values are Ti content, Al level (cleanliness), and nitrogen — all provided per lot with addition-yield reference data.
Yes — our wire-fill grades are sized and flowed for filling lines, with chemistry certified to the wire producer's specification. We supply several wire manufacturers on annual contracts.
Full chemistry per lot (including gases), size distribution, and retained samples. For IATF-audited mills we provide SPC data and change-control agreements.
No. Both are standard ferroalloy products shipping without licensing requirements.
