What does nitriding do to steel?
Nitriding steel is steel treated by a highly specialized surface hardening process known as nitriding, which is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. Case-hardening is a simple process of hardening the surface of a metal object.
How can you tell if steel is nitrided?
Other tests that you can perform to see if the piece of steel has nitriding or not, is to analyze it by X-ray diffraction, by Dilatometric test or by Fluorescence.
What is the effect of nitriding?
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.
What is nitriding steel and what does it mean?
What Does Nitriding Steel Mean? Nitriding steel is steel treated by a highly specialized surface hardening process known as nitriding, which is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. Case-hardening is a simple process of hardening the surface of a metal object.
Is hybrid steel good for nitriding?
Nitriding steel grades contain strong nitride formers such as molybdenum, vanadium, aluminum or chromium. Ovako’s family of Hybrid Steel can very favorably be used for nitriding. Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface.
What temperature can you nitride stainless steel?
For instance, at moderate temperatures (like 420 °C), stainless steels can be nitrided without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties. In the plasma nitriding processes, nitrogen gas (N 2) is usually the nitrogen carrying gas.
When is plasma nitriding used for high alloy steel?
For high alloy steels, plasma nitriding is preferred to reduce the treatment temperature, increase nitrogen activity and prevent the onset of grain boundary precipitation ( Yagita and Ohki, 2010 ). Table 10.2 gives some applications of a number of nitrided steel grades for surface and volume fatigue life improvement.
