Machine equipment in fermentation industry suffers from the mechanical wear of mobile elements and from the corrosion degradation. Especially concerned are lines for filling kegs and bottles and labelling machines. Thus the effort of technical designers is to replace classic steels by corrosion-proof materials. The aim of this paper is to compare corrosion resistance of standard used steel C45E with the anticorrosion steel X20Cr13 and X5CrNi 18-10. Tests were carried out on samples which were heat treated according to the producer's recommendations. Samples which were non heat treated serve as measurement standards. Abrasive wear was tested using the equipment with solid particles according to the norm ČSN 01 5084. Metallographic scratch pattern of the individual samples was pursued before the test itself, microhardness of structure phases of the material was measured. For comparison, total macrohardness (method HRC) was measured as well.Machine equipment in fermentation industry suffers from the mechanical wear of mobile elements and from the corrosion degradation.
