High silicon moly ductile iron
WebDec 1, 2012 · In Charpy impact tests, the ductile-to-brittle transition temperature could be reduced by about 55 °C by reducing the silicon content to 2.95 wt% and adding 0.21 wt% molybdenum compared to a high ... WebOct 9, 2024 · Sulfur, an element that belongs to group 16 (chalcogens) of the periodic table, is an excellent promoter of nucleation substrates for graphite in cast iron. In ductile iron, sulfur favors a higher nodule count, which inhibits the risk of carbides and of microporosity. It is reasonable to expect that other elements from group 16, such as selenium or …

WebOct 10, 2012 · SiMo is a nodular cast iron typically containing 4–6 % Si and 0.5–2 % Mo and can be used in temperatures up to 850–860 °C. D5S is a nickel base material. High silicon … WebJul 14, 2024 · In silicon–molybdenum ferritic ductile iron, silicon content is maintained around 4–6% and molybdenum (Mo) addition up to 2%. The higher percentage of silicon content as compared to the common ductile irons helps to develop the ferritic matrix even at high temperature by increasing the ferrite to austenite transformation temperature.
Webaddition to these high Si-Ti castings, a 4.5 wt% Si ductile iron and 4.4 wt% Si-0.84 wt% Mo ductile iron were also cast and evaluated. For the molybdenum containing iron, 60% ferro-molybdenum was added to the furnace. The carbon and silicon contents of the base iron were determined using an Electro-Nite QuiK Cup containing tellurium. The irons were
