13/01/12 - "Our Gas Nitrider is down for repairs until the end of April 2012. Stay tuned for updates". This low temperature case hardening process is ideal for producing hardened surfaces on pre-heat treated alloy steels such as 4140 and 4340, pre-heat treated tool steels such as H13, and specialty grades such as Nitralloy 135M.                       Gas Nitrided Nitralloy 135M Microstructure

Gas Nitriding

• Benefits of gas nitriding include: high surface hardness, improved wear resistance, improved anti-galling properties, better fatigue life.

• Gas nitriding is especially suitable for pre-heat treated alloy steels and tool steels. The relatively low process temperature makes the process ideal for parts where low distortion and deformation are important. 

Process selection and Quality Control

Process quality controls include:

• Complete control of temperature, time, and atmosphere.

• Random microhardness case depth surveys on our in-house coupons.

• Temperature uniformity surveys of furnaces
