cast iron powded by milling process

Chapter 17. Processing of Metal Powders

1 Chapter 17. Processing of Metal Powders 17.1 Introduction This chapter describes the powder metallurgy (P/M) process, in which metal powders are compacted into desired and often complex shapes and sintered (heated without melting) to form a solid piece. This process first was used by the Egyptians in about 3000 B.C. to iron tools. One of its first

What type cast iron for milling machine table.

I doubt is your mill table is "plain" cast iron. It's more likely one of the harder alloys in a large family of cast irons the recipes for which fill a thick red book to be found in every metallurgist's personal library. ASM Specialty Handbook: Cast Irons - Google Books I seem to recall "Meehanite" is a proprietary process, not a specific alloy.

Aufhauser - Technical Guide - Cast Iron Welding Procedures

Cast Iron is considerably less weldable than low-carbon steel. Cast iron contains much more carbon and silicon than steel, with the result that cast iron is less ductile, and is more metallurgically deformed when welded. However, there have been many successful cast iron repair welds performed in maintenance and casting reclamation applications.
