Using state of the art furnace and process control ensures minimum “white layer” and repeatable metallurgical results avoiding post heat treatment machining. Low temperature processing results in minimal dimensional changes. Note: We would recommend a full stress relief after rough machining. Close control of time, temperature and dissociation results in a controlled white layer depth.
Versatility of the cycle ensures predictable metallurgical results through a range of case depths ranging from 0.1 mm up to the more traditional 0.7 mm depth. Suitable for a range of alloyed materials that
include Aluminium, Chromium, Molybdenum and Vana- dium. Can include unalloyed or lean alloyed steels. Typical components processed include: General Engineering Items, Gears, Crankshafts, Camshafts, Cam Followers, Die/Extrusion and Mould tooling.
A range of Nitrocarburising processes to meet customer requirements using state of the art programmable furnace and process controls. Programmes available include ferritic nitrocarburising, austenitic nitrocarburising and extended austenitic nitrocarburising.
Control of processing parameters ensures that a range of properties that include wear resistance, enhanced corrosion resistance, minimum distortion and aesthetic appeal can be achieved. Dependent on material type and process case depths up to about 1mm can be achieved.
Ferritic Nitrocarburising is suitable for the processing of mild steel, medium carbon steel, nodular iron, cast iron and all nitrideable steels. The process is applicable to crankshafts, gears, moulds, dies etc. Austenitic and extended austenitic Nitrocarburising are suitable for mild steel and low alloy case hardening steels. The process is particularly suitable as an alternative for the processing of thin section components that distort under classical case hardening.
