Abstract
The possibility of replacing of forged blanks made of 12X18H10T steel with shaped castings obtained by casting into thin-walled metal shell molds with forced cooling is considered. Comparative tests of forged blanks made of 12Х18Н10Т steel and cast ones for strength, plastic properties and impact strength are carried out. Macrostructures, sulfur imprints, and distributions of non-metallic inclusions are studied. It is been established that cast billets are not inferior to forged ones in terms of a set of mechanical properties indicators. With a slight decrease in strength, cast workpieces are characterized by greater plastic properties and toughness. Keywords 12X18H10T and AISI 321 steels, alloy, structure, crystallization, casting, non-metallic inclusions, mechanical properties, metal shell shape
