Carburizer for Malleable Steel

Malleable steel is cast into white billets with a certain carbon equivalent of molten iron, and then annealed cast iron, which has higher strength, plasticity and impact toughness, and can partially replace carbon steel. The toughness of malleable steel pipe fittings is an important index to measure the quality of pipe fittings. Good malleable steel pipe fittings must have a certain degree of toughness and ensure no cracks within a certain deformation range. Cementite is a simple mixture of carbon and iron. Because of the simple combination, its mechanical properties are very poor, which directly causes the raw blanks of malleable steel pipes to become brittle and easy to crack. It is easy to break when hit by force, so the pipes must be annealed. The good technical indicators of the carburizer for malleable steel can greatly increase the disintegration and absorption rate during the use of the carburant. Its unique graphite form can minimize the matrix splitting in malleable steel parts and increase the content of pearlite. The formation of cementite is reduced, and the mechanical strength and ductility of the finished malleable steel pipe fittings are qualitatively improved, so that high-quality malleable steel parts can be produced.
