Abstract
In this study, corrosion behaviors of diffuser unit solution by which raw sugar is produced from minced sugar beets in sugar factories on St-37 low alloy steel and AISI 304, 304L, 316 austenitic stainless steel types were examined. Moreover, influence of heat treatment on corrosion resistance was investigated. Corrosion tests were performed using mass loss method. SEM-EDX, X-rays Diffraction, microhardness and surface hardness analyses of samples were carried out. As a result, it was determined that AISI 304L and 316 steels have better corrosive resistance and heat treatment improves corrosion resistance.
Highlights
Corrosion is a significant problem with an economic dimension causing degradation because of chemical and electrochemical reactions entered by metals and alloys with their environment
It was determined that heat treatment improved corrosion resistance of samples due to both decline in particle size and dissolution of carbides
Corrosion resistance is better in AISI 316 and AISI 304L steels
