WebJan 30, 2024 · Nikrothal ® 80/20 Cb is an austenitic nickel-chromium alloy (NiCr alloy) with addition of niobium. It is characterized by high mechanical strength and suitable for furnace temperatures up to 1200°C (2192°F). Typical applications for Nikrothal ® 80/20 Cb are as wire in mesh belts. Chemical composition Mechanical properties Physical properties The creation of metal alloys account for 85% of the available chromium's usage. The remainder of chromium is used in the chemical, refractory, and foundry industries. The strengthening effect of forming stable metal carbides at grain boundaries, and the strong increase in corrosion resistance made chromium an important alloying material for steel. High-speed tool steels contain between 3 and 5% chromium. Stainless steel, the primary corrosion-re…
