What is the content of silicon in silicon molybdenum ductile iron?
Customers generally give a wide range, most of the national standard "reference" the United States of similar brands suspected. Especially 3.75-4.25% Si too big. We can narrow the scope according to their actual situationHowever, the high Si content of the end we can pregnant before Si% and several birth control adjustment. I personally think that many times easy inoculation, increased nucleation; more than 517 in terms of strength, the lower the content of Mn, some clients request F content in more than 95%, but do not worry about the intensity of the problem, even if the F matrix as long as the components of control will be above 517. Spheroidizer we can choose good quality, spheroidization time have good control over 60S,
Silicon molybdenum material, similar to the United States IDM5381, 5402 and other brands, engaged in automotive components (such as turbocharger parts), and other heat resistant parts have been exposed to high temperature
High silicon molybdenum ductile cast iron is developed for end users successfully reduces the cost, and the castings have high strength, good oxidation resistance, and has good performance under thermal cycling condition. This kind of ductile iron silicon content of 4% molybdenum content 0.6%-0.8%, currently designated as many car manifold and turbocharger shell, and molybdenum content than the silicon alloy casting 1% more for special high temperature exhaust pipe, heat treatment. High silicon molybdenum alloy nodular cast iron castings used in the production of automotive turbocharger.
