CERAMIC AND CARBIDES DIE MATERIALS

CERAMIC AND CARBIDES DIE MATERIALS

Potential use of ceramics and carbides has been found be gaining interest for use in

warm and hot forging applications. Ceramic inserts and coatings are well established in

the machining industry for reducing tool wear and enhancing the tool per formance.

Some of the ceramic materials have marked improvements over the traditional hot work

die materials (Cr-Mo-W based steels) used in hot forging

DIE MATERIALS FOR FORGING OF STEEL

DIE MATERIALS FOR FORGING OF STEEL

There are various tool steels which are used in forging. Although in hot and warm

forging, mainly hot work die steels are used due to their ability to retain their hardness at

elevated temperatures with sufficient strength and toughness to withstand the stresses

that are imposed during forging. There have also been some successful applications of

other materials such as ceramics, carbides and super alloys although their application is

limited due to design and cost of manufacturing. The selection of die material grade and

subsequent treatment affects the mode of failure and rate of tool failure.

Cogging

Successively reducing the thickness of a bar with open die forging
•Also called drawing out
•Reducing the thickness of a long section of a bar without
excessive forces or machining

a cogging operation on a rectangular bar. Blacksmiths use this process to reduce the thickness of bars by hammering the part on an anvil. Note the barreling of the workpiece.
