Gas Nitriding

Gas Nitriding as a process, has been used industrially since the early 1920's. The process is carried out in a sealed retort furnace at temperatures between 490°C and 530°C in a flowing Ammonia atmosphere for times up to 120 hours. Gas Nitriding delivers  hardened steel as the output. In many instances where hardened steel is the specifrication, then Gas Nitriding could be the ideal process to adopt.
Hauck HT Ltd.offers extensive Gas Nitriding capacity from Telford and Letchworth with 20 furnaces of various sizes. Surface hardening of steel is the result of an atmospheric process, which may involve an ammonia atmosphere in which thye treatment takes place. Our largest Nitriding capacity is at Telford where furnaces are capable of processing parts up to 4.4m high and 1.2m diameter. 

Why Nitride? 

Gas nitriding is normally carried out on hardened and tempered and fully stabilised parts to produce a hard wear resistant case, enhanced corrosion resistance and good fatigue performance. 

The process is usually performed on fully finished components which, in many instances, require no additional operations prior to assembly. 

Whilst Gas Nitriding is normally applied to low alloy steels it is possible to nitride other materials such as stainless steel, titanium and nickel alloys, however the preferred nitriding route for those materials is Plasma Nitriding. 

Hauck HT have extensive knowledge and expertise in all Nitriding Treatments.
