17-4PH vs X50CrMoV15
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.
X50CrMoV15
1.4116
Premium martensitic stainless steel with 0.50% C, 15% Cr, Mo and V additions. The signature blade steel of German knife manufacturers (Wüsthof, Zwilling J.A. Henckels, Victorinox Swiss Army). Mo and V improve corrosion resistance, hardenability, and toughness beyond basic Cr13 grades. Achieves 55-57 HRC. Excellent rust resistance, easy sharpening, and good edge retention. Also known as Krupp 4116. Equivalent to 5Cr15MoV (Chinese).
