17-4PH vs X46Cr13
Side-by-side chemical composition and mechanical property comparison.
Overview
17-4PH
1.4542
The most widely used precipitation-hardening stainless steel. Combines high strength (up to 1310 MPa UTS) with corrosion resistance comparable to 304. Delivered solution-annealed and hardened by simple low-temperature aging. Used in aerospace, medical, oil & gas, and nuclear applications.
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.
