304 Stainless Steel vs X2CrNiMo17-12-2
Side-by-side chemical composition and mechanical property comparison.
Overview
304 Stainless Steel
1.4301
The most widely used austenitic stainless steel. Excellent corrosion resistance, good formability and weldability. Standard choice for food processing, chemical, and architectural applications.
X2CrNiMo17-12-2
1.4404
Low-carbon molybdenum-bearing austenitic stainless steel, widely known as AISI 316L. The Mo addition (2–2.5%) significantly improves resistance to pitting and crevice corrosion compared to 1.4301 (304). Low carbon content (max 0.03%) ensures resistance to intergranular corrosion after welding without post-weld heat treatment. Standard grade for pharmaceutical, petrochemical, chemical and marine applications. PREN 23–29.
