Härte wird als der Widerstand definiert, den ein Körper gegen das Eindringen eines anderen in seine Oberfläche entgegensetzt. In materials testing, there are therefore a number of so-called penetration processes, although there are also tests for rebound hardness and surface-scratch hardness...

Treatment of grinding tools made of stainless steel Dear Customer, In a lot of cases, grinding tools and accessories of RETSCH grinding machines are made of stainless steel. Nevertheless you may find small corrosion spots on stainless steel tools especially after a certain time of usage. This may cause the impression that there is a material failure. The word “stainless” describes the resistance against corrosion in a damp environment. The resistance against corrosion regarding other solid, liquid or gaseous media, as well as against mechanical stress, has to be investigated separately. The stainless...
