What is Expanded Austenite or “S-phase”?

The terms “expanded austenite” and “S-phase” were coined when first discovered in the early 1980s. The term S-phase was used to describe new peaks shown with X-ray powder diffraction (XRD) device. It was believed that a new phase was formed in the austenitic structure of stainless steels. It was later discovered this was not true…

The frequently asked questions of Kolsterising ®

Microhardness vs. diffusion depth of treated stainless steel 1.4404 (316L) and hardness conversion table Kolsterising ®, proprietary to Bodycote, is a technology that greatly improves the mechanical properties of corrosion-resistant materials. Some of the more commonly asked questions from our customers are answered below. Conventional heat treatments, such as nitriding or nitrocarburizing will negatively impact the corrosion resistant properties…

What Is Galling? https://blog.bodycote.com/wp-content/uploads/2016/10/8443-4-Macro.jpg 1600 1200 The Bodycote Blog The Bodycote Blog https://blog.bodycote.com/wp-content/uploads/2016/10/8443-4-Macro.jpg

What Is Galling?

Galling is a type of mechanical wear caused by a combination of friction and adhesion between sliding surfaces typically under a compressive load. It is the result of tearing and slipping of the crystal structure at the surface once the protective chromium oxide layer has worn away. Further mechanical forces cause the material to become…

What is the difference between nitriding and Bodycote’s Corr-I-Dur® process? https://blog.bodycote.com/wp-content/uploads/2017/06/corridur1.jpg 1920 834 The Bodycote Blog The Bodycote Blog https://blog.bodycote.com/wp-content/uploads/2017/06/corridur1.jpg

What is the difference between nitriding and Bodycote’s Corr-I-Dur® process?

Thanks to the wide range of applications, Nitriding and Nitrocarburising processes are becoming more and more important. In addition to mechanical and technological characteristics, corrosion resistance is of vital importance for the functionality of surfaces. The Corr-I-Dur® process not only enhances wear properties, but also significantly improves the corrosion resistance. Corr-I-Dur® has very little effect…

How does one achieve optimum results with Corr-I-Dur®? https://blog.bodycote.com/wp-content/uploads/2017/06/corridur2.jpg 1920 888 The Bodycote Blog The Bodycote Blog https://blog.bodycote.com/wp-content/uploads/2017/06/corridur2.jpg

How does one achieve optimum results with Corr-I-Dur®?

The achievable surface hardness mainly depends on the base material. Alloying elements such as chrome and aluminium lead to higher hardness. The Nitriding depth depends on customer requirements. Also the component’s condition at delivery, i.e. distortion, heat treatment status also affect the layer parameter to be achieved. Dimensional changes can further be positively influenced by…
