Alloy 20 is a chromium-iron-nickel-based, austenitic alloy that comes with excellent corrosion resistance in chemical environments. It contains sulfuric acid and many aggressive media well. The alloy is stabilized with niobium that helps it to resist intergranular corrosion. Alloy 20 can help provide potential cost savings compared to the higher nickel-based alloys as it outperforms standard stainless steel.
Alloy 20 are commonly known as UNS N08020, is a high alloy pipe made of unique stainless steel grade with excellent resistance to the chloride and sulfuric acid stress corrosion cracking. The alloy contains copper content that helps in providing excellent general corrosion resistance. Due to its resistance to pitting, crevice corrosion, and corrosion, the stainless steel alloy is widely used for manufacturing pickling equipment, process piping, heat exchangers, and manufacturing tanks.
Alloy 20 pipe fittings, Alloy 20 flanges, and other Alloy 20-grade products are helpful in various applications throughout the chemical process industry, paper manufacturing, industrial heating equipment, plastics, synthetic rubber, pharmaceuticals, and chemical process industry.
