Alloy 20 is considered a nickel-chromium-molybdenum stainless steel alloy which has a wide variety of uses within the sulfuric acid industry. Alloy-20 fasteners are highly resistant to many other chemicals. Also known by many as Carpenter 20, these fasteners are desired by many engineers because they are resilient against pitting and chloride corrostion from sulfuric acid.
