Sažetak
In this research the load capacity and corrosion behavior of quenched and tempered steel 42CrMo4 and cast steel GS-42CrMo4 was investigated. Load capacity and corrosion behavior of steel and cast steel depend on processing history. The influence of processing parameters on load capacity, i.e. strength and toughness was investigated by using the 25-2 factor experiment. It was found out that yield strength is insensitive on differences between applied manufacturing processes, but by application of hot working (plastic deformation above recrystallization temperature) and with proper pouring temperature the Charpy-V notch toughness is increased. Also, Charpy-V notch toughness is increased by interactive effect of the proper cooling rate during the casting and hot working. Corrosion behavior was evaluated by electrochemical measurements in 3.5 % aqueous solution of sodium chloride, NaCl. It was found out that by application of hot working the corrosion resistance is increased. Microstructure analysis shows that hot working leads to refining of microstructure and thus increasing load capacity and corrosion resistance of steel. It was found out that ASTM grain size number of prior austenite was equal to N.6-N.7 for steel processed by hot working, and N.4-N.5 for cast steel processed without hot working.
