Alloy Products, Incorporated RegentSteel has been supplying pipe, valves, fittings, flanges, and miscellaneous piping components and structural products over many years. Although we consider ourselves to be the Nickel Alloy experts in the international market, our product line is extremely broad.
The nickel content makes INCO alloy 20 resistant to chloride-ion stress-corrosion cracking. Copper and molybdenum give resistance to reducing environments. The molybdenum content also provides good resistance to pitting and crevice corrosion. The chromium gives resistance to oxidizing environments such as nitric acid. The addition of niobium reduces the effect of carbide precipitation during welding, thus increasing the alloy's resistance to intergranular corrosion.
