Nitriding case depth

WebbCase depth can be varied by extending or reducing cycle time. Longwear offers cycle times from 12 to 90 hours duration on a regular, scheduled basis. The case properties achievable with commonly nitrided materials can be seen in the chart below: 12 hour cycles - 24 hour cycles - 45 hour cycles - 90 hour cycles - Webb13 okt. 2024 · The nitriding of forging tools is an industrially established standard used to increase the hardness of the tool surface layer and reduce wear. However, this modification of the tool surface layer, as well as the microstructural changes that occur during this operation due to the thermo-mechanical load, cannot be considered during …

Methods for Nitriding Methods Case-Hardening

Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-alloy steels. They are also used on titanium, aluminium and molybdenum. Typical applications include gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, die-casting tools, forging dies, extrusion dies, firearm comp… WebbNitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface.

WebbGas nitriding allows for nitriding to much deeper case depths on stainless steel than liquid nitriding, and white layer control results in far fewer nitride networks. Gas nitriding also allows for specialized procedures to nitride stainless steel without impairing the corrosion-resistance, but this comes at the expense of case depth.
