316L vs X50CrMoV15
Side-by-side chemical composition and mechanical property comparison.
Overview
316L
1.4404
Low-carbon austenitic stainless steel with molybdenum addition. Superior corrosion resistance to 304, especially against chlorides and pitting. Standard choice for chemical processing, marine, medical implants, and pharmaceutical equipment.
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).
