316L vs X46Cr13
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.
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.
