2008-Jun-23 - Iron Castings Info

Iron castings are utilized extensively in machinery, automotive, and agricultural industry. Parts such as turbine and pump housings, dynamometer bases, compressors are made out of iron castings. Majority of manufacturers have the caliber to go for high and low production outputs. They are also entitled to go for short order runs. There are standard prototypes ensuring customer satisfaction and accuracy. Some manufacturers provide finishing services like galvanizing, painting, and machining as well. In general, iron castings include alloy casting, ductile castings, and malleable castings. There are some terms relating to iron castings. They need to be known in order to get a fair idea of iron.

Brinell Hardness Number (BHN): It can be defined as the method used for measuring the hardness of iron. For iron castings, a metal ball of 3000Kg is put on a flat iron piece. After the removal of ball, indentation observed is recorded. This measurement indicates the value of hardness.

Tensile Strength: Tensile strength can be defined as the quantity of bending and stretching undergone by a material before tearing or breaking. Here the metal is iron.

Modulus of Elasticity: It can be defined as the ratio of stress to strain. This value determines the elasticity as well as the stiffness of the concerned material.
