904L Stainless Steel is a highly alloyed austenitic grade known for exceptional resistance to corrosion in acidic environments. With elevated nickel and molybdenum content, 904L is particularly resilient to chloride stress corrosion, pitting, and crevice corrosion. Originally developed for sulfuric acid applications, this alloy is ideal for use in harsh chemical, marine, and industrial settings due to its excellent durability, toughness, and formability. Its low carbon content further prevents intergranular corrosion after welding.
