15-5PH / X5CrNiCuNb15-5 vs X46Cr13
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.
X46Cr13
1.4034
Martensitic chromium stainless steel with high carbon content (0.43-0.50%) and 12.5-14.5% Cr. The highest carbon grade in the basic Cr13 martensitic series. Achieves hardness up to 56 HRC. Good compromise between hardness and corrosion resistance. Equivalent to AISI 420C/420HC. Used for knife blades, surgical instruments, razor blades, CO2 capture pipes, and precision cutting tools. Good polishing capability.
