Nitriding vs. Carburizing: Select the Right Route
Compare nitriding and carburizing against material, case depth, distortion risk, machining sequence, and inspection requirements before releasing a drawing.
Compare Nitriding and Carburizing by Critical Design Criteria
Use the drawing, duty cycle, material condition, and inspection priorities to determine the appropriate surface-hardening route before production planning.
Required Case Depth
Define effective hardened depth and load path first; deeper case requirements may change the preferred route, machining allowance, and verification plan.
Distortion Risk
Review datums, thin sections, tight fits, and post-treatment geometry to determine whether distortion risk requires a different sequence or finishing strategy.
Material Compatibility
Confirm steel grade, core-property requirements, and heat-treatment condition before selection; alloy response and application loads must support the specified case treatment.
Downstream Finishing
Plan grinding stock, critical surfaces, and inspection method early so finishing operations protect functional dimensions after heat treatment.
