FeW

Ferro tungsten (FeW80) delivers a high tungsten unit into liquid steel without the melting losses of metallic W. Once dissolved, tungsten forms stable carbides (WC, W2C) and complex M6C phases that resist dissolution and coarsening at elevated temperature. This is the mechanism behind red-hardness: the tool keeps its cutting edge and hardness even when the tip glows during machining. Tungsten also raises hot strength and abrasion resistance, which is why it anchors high-speed steel (HSS), tool and die steels, hard-facing alloys, and heat-resistant grades. Additions are tuned to target W chemistry, commonly a few tenths up to several wt% depending on grade. The FeW80 cut carries W 75-82% with controlled C (≤0.5%), Si (≤0.7%), Mn (≤0.25%), and low P (≤0.04%) / S (≤0.08%), so the master alloy stays clean and adds minimal tramp residuals to the heat; 10-50mm lump suits clean charge handling and predictable recovery. Each lot ships with COA and MTC for full traceability. Multi-regional sourcing supports CIF Marmara and Gebze bonded stock, FCL or LCL. Send your target grade for an RFQ.
