304 Stainless Steel vs X2CrNiMoN25-7-4
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.
X2CrNiMoN25-7-4
1.4410
Super duplex stainless steel (SAF 2507 / UNS S32750) with 25% Cr, 7% Ni, 4% Mo, and high N for PREN ≥42. The highest corrosion resistance and strength among standard duplex grades — YS ≥550 MPa is ~2.5× that of 316L. Service temperature up to 300°C. Used for subsea oil & gas equipment (manifolds, trees, risers), desalination plants, flue gas cleaning, chemical tankers, and mining equipment in severe chloride environments. Requires careful welding to avoid sigma phase.
