【Abstract】 The manufacture and process techniques of the wrought Mo alloy piercing mandrel have been introduced. The piercing process of 1Cr18Ni9Ti stainless steel tubes using wrought Mo alloy piercing-mandrel in production has been cartied out successfully, and a Bignificant effect can be achieved by supplementing with glass Iubricant. The surface quality of both inner and outer tube have also been improved.更多还原
