As a Malleable Iron Pipe Fittings Supplier, today we would like to share the Malleable iron for you.
Malleable cast iron (malleable cast iron) is a kind of cast iron made from liquid iron of certain chemical composition and then annealed, which has high strength, plasticity and impact toughness and can partially replace carbon steel.
Introduction to the malleable cast iron:
Malleable white cast iron is a kind of high strength and toughness cast iron obtained by graphitization annealing. High strength, plasticity and impact toughness, can partially replace carbon steel. Compared with gray cast iron, malleable cast iron has better strength and plasticity, especially better impact performance at low temperature, better wear resistance and vibration reduction than ordinary carbon steel. Due to its ductility and toughness, malleable iron is commonly known as malleable iron and malleable iron. Black heart malleable iron is used for impact or vibration and torsion load parts, often used in the manufacture of automobile rear axle, spring bracket, low pressure valve, pipe joint, tool wrench, etc. Pearlitic malleable cast iron is commonly used to make wear-resistant parts for power machinery and agricultural machinery. White heart malleable cast iron is seldom used because of its long annealing time (see ferritic malleable cast iron, pearlitic malleable cast iron and white heart malleable cast iron).
The production process of the malleable cast iron:
The white cast iron is first cast, and then malleable cast iron is obtained by malleable annealing (malleable annealing causes the cementite to decompose into a group of flocculous graphite).
Chemical composition:
The chemical composition of malleable cast iron is: wC = 2.2% ~ 2.8%, wSi = 1.0% ~ 1.8%, wMn = 0.3% ~ 0.8%, the wS 0.2% or less, wP 0.1% or less.
Malleable cast iron has two types of microstructure:
Ferrite (F)+ group flocculent graphite (G);
Pearlite (P)+ group flocculent graphite (G).
