Introduction Of Malleable Steel

Malleable white cast iron is a kind of high-strength and tough cast iron obtained by graphitization and annealing. It has higher strength, plasticity and impact toughness, and can partially replace carbon steel. Compared with gray cast iron, malleable cast iron has better strength and plasticity, especially better low temperature impact performance, and better wear resistance and vibration damping than ordinary carbon steel. This kind of cast iron is commonly known as malleable steel, horse iron, or malleable cast iron or ductile cast iron because of its definite plasticity and toughness. Black-heart malleable iron is used for shock or vibration and torsion loaded parts, commonly used in the manufacture of automotive rear axles, spring brackets, low pressure valves, pipe joints, tool wrenches, etc. Pearlitic malleable iron is often used to manufacture wear-resistant parts of power machinery and agricultural machinery, and there are international examples of being used in the manufacture of automotive camshafts. White-heart malleable iron is less used due to its long malleable annealing time (see ferritic malleable iron, pearlitic malleable iron, and white-heart malleable iron).
