15-5PH / X5CrNiCuNb15-5 vs 430 Stainless Steel
Side-by-side chemical composition and mechanical property comparison.
Overview
15-5PH / X5CrNiCuNb15-5
1.4545
Martensitic precipitation-hardening stainless steel. Similar to 17-4PH but with better transverse ductility and toughness due to lower delta ferrite. Used for aerospace structural components, nuclear reactor parts, food processing equipment, and high-performance fasteners.
430 Stainless Steel
1.4016
Ferritic chromium stainless steel with good corrosion resistance and formability. Lower cost than austenitic grades. Used for automotive trim, kitchen sinks, architectural panels, and appliance components.
