| Abstract: | 1Mn18Cr18N steel is a nonmagnetic high Mn austenitic stainless steel, this steel has higher alloy element content, its forging temperature range is very narrow, and the surface crack may be produced most likely during forging. The quality ingot has been obtained by electric furnace smelting and electroslag remelting. The heating temperature for forging is 1190-1210℃, the temperature of forging end is above 900℃. The many times heating and forging with small percent reduction has been performed to minimize the surface crack, the retaining ring forgings which met the consumer requirement have been produced after solution treatment. |
