What is malleable cast iron used for?
What is malleable cast iron used for?
Applications of malleable cast irons include many essential automotive parts such as differential carriers, differential cases, bearing caps, steering-gear housings . Another uses include hand tools, brackets, machine parts, electrical fittings, pipe fittings, farm equipment and mining hardware.
What is the raw material required for malleable cast iron?
It is produced by reducing iron ore in blast furnaces, and its primary material is cast iron produced from molten iron ore in the furnace. These irons are made directly from molten pig iron or by smelting pig iron, often with a substantial amount of iron, limestone, steel, or coke.
Is malleable iron the same as cast iron?
Malleable iron, just like cast iron is produced by a casting method but they are actually quite different from each other. Although, Malleable iron fittings start out as a cast iron fittings, they are then transformed into a much more durable malleable iron through a heating process.
What is malleable casting?
Malleable cast iron is essentially white cast iron which has been modified by heat treatment. It is formed when white cast iron is heated to around 920 deg C and then left to cool very slowly.
What is the carbon content of malleable cast iron?
Malleable cast iron is a heat-treated iron-carbon alloy, which solidifies in the as-cast condition with a graphite-free structure, i.e. the total carbon content is present in the cementite form (Fe3C)….Chemical composition of malleable iron.
Element | Composition % |
---|---|
Phosphorus | 0.02-0.15 |
What are the materials used in cast iron?
cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.
Does malleable cast iron rust?
Malleable iron is relatively easy to machine, and it is shock resistant. Cast iron contains about two percent carbon, which makes it stronger and more resistant to rusting.
How is cast iron manufactured?
It is made by reducing iron ore in a blast furnace. The liquid iron is cast, or poured and hardened, into crude ingots called pigs, and the pigs are subsequently remelted along with scrap and alloying elements in cupola furnaces and recast into molds for producing a variety of products.
How are malleable iron fittings made?
Malleable iron fittings are made using the most sophisticated metallurgical and processing controls. These fittings are usually made through casting and an automatic precision pattern extrusion. Malleability occurs due to metallic bonding present in most metals.
