CORROSION OF STEEL AND SPHEROIDAL FERRITIC CAST IRON IN LIQUID TIN

The article presents a course of static corrosion of spheroidal ferritic cast iron, austenite stainless steel X2CrNi19-12 (00H18N10) and samples of low-alloy construction steel 12CrMo4-5 (15HM) in liquid tin. The tests were performed at temperature of 600°C in liquid tin for 170 hours. It has been found, that the fastest corrosion was observed in austenite steel (average rate ca. 0.12 mm/h). Slower corrosion was observed in steel 12CrMo4-5 (average rate ca. 0.004 mm/h) and the slowest corrosion was observed in spheroidal ferritic iron cast specimen (average rate ca. 0.003 mm/h)  in liquid tin.
