General information
White cast iron that is modified by heat treatment is known as malleable cast iron (MCI). These fittings are widely used pipe fittings because of their durability and mechanical strength. They are used to connect steel pipes.
These fittings have a high resistance to cracking, high values of tensile strength, rupture strength and elongation, and can resist wear and tear. Malleable cast iron is often used as a substitute to steel since it is cheaper to produce and use.
