Heat Treatment and Properties of Iron and Steel

The properties of cast iron also may be modi- fied by the presence of alloying elements—such irons are called alloy cast irons. 2. Properties of Iron Since iron is the basic element of steel, a knowledge of some of its properties is dataa pre- requisite to an understanding of the funda- mental principles underlying the heat treatment of Get price

Casting Process

1.4.1 Heat conduction in the mold controls the heat transfer: expendable ceramic molds (sand casting, investment casting) used for shape casting Molds made out of ceramics conduct heat so slowly that the entire temperature drop occurs across the mold (i.e. temperature in solid and liquid metal and mold–metal interface are equal and thus at Get price

Weldability of Materials

Job Knowledge 25. Cast irons are iron based alloys containing more than 2% carbon, 1 to 3% silicon and up to 1% manganese. As cast irons are relatively inexpensive, very easily cast into complex shapes and readily machined, they are an important engineering and structural group of materials. Get price
