Side-by-side chemical composition and mechanical property comparison.
Overview
304 / X5CrNi18-10
1.4301
The world's most widely used stainless steel — the original 18/8 austenitic. Good corrosion resistance in atmospheric, organic, and inorganic environments. Excellent formability and weldability. Not recommended for chloride-rich or marine environments (use 316L). Used in food processing, kitchen equipment, architecture, tanks, and general engineering.
X10CrNi18-8
1.4310
Work-hardening austenitic stainless — AISI 301. Higher C (0.05-0.15%) than 301LN enables extreme cold-work strengthening to UTS 1300+ MPa in full-hard temper. THE spring-temper stainless: used for flat springs, retaining clips, conveyor belts, automotive structural parts, and rail car body panels. Corrosion resistance similar to 304 in annealed state.
