Made in the USA. It is often used for small castings requiring good tensile strength and the ability to flex without breaking (ductility). Cast iron in which carbon is present in combined form or in carbide form known as white cast iron. It has excellence machining property. The hardness of high alloy white cast iron castings usually fall in the range of HB 450 to HB 800, whereas the hardness of low alloy white cast iron (alloying content less than 4 %) castings normally is in the range of HB 350 to HB 550. Please click here if you are a supplier and would like information on how to add your listing to this material. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding White cast iron is unique in that it is the only member of the cast iron family in which carbon is present only as carbide. It is designate by SG followed by the numbers which indicate tensile strength and percentage elongation. Under this system, grey cast irons are graded according to their tensile strength, with class 20 grey cast iron, for example, having a minimum tensile strength of 20,000 psi (140 MPa). Average value: 6.11 ohm-cm Grade Count:18, Average value: 12.7 µm/m-°C Grade Count:29, Average value: 0.506 J/g-°C Grade Count:3. Brinell Hardness 550-650 min. This cast iron is obtained from white cast iron by heat treatment process. For example, the ductile iron 60-40-18 has tensile strength of 60000 psi, therefore, it is equal to 414 Mpa. It is also known as commercial cast iron due to mostly used in commercial purpose. Overview of materials for Cast Iron Categories: Metal; Ferrous Metal; Cast Iron. Your email address will not be published. It has intermediate property and colour of Gray cast iron and white cast iron. Alloy cast iron produced by adding some alloying element in cast iron like nickel, chromium, copper etc. This results into low cost of its products. This cast iron is produce to get desire properties of cast iron. This is all about what is cast iron and types of cast iron. calculations can click on the property value to see the original value as well as raw conversions to equivalent units. Uses include electrical fittings, hand tools, pipe fittings, washers, brackets, fence fittings etc. The comments report the average value, and number of data points used to calculate the average. Due to its casting properties it is named as cast iron. White cast iron has high compressive strength and retains good hardness and strength at higher temperature. Mechanical Properties. 3. Max Bend Stress / Yield Strength 188 KPSI. White Cast Iron. Cast iron is a brittle and less ductile material which has high compressive strength. 3. Cast iron which contain carbon in free form, known as Gray cast iron. The effect of these properties is as follow.

Cast iron also contain small quantity of impurities such as silicon, sulphur, manganese and phosphorus, copper, nickel, chromium, which effect its properties small or large level. Iron. %PDF-1.6 %���� It is mostly obtain by annealing of white cast iron. pouring to ensure exact chemical composition. Izod Impact 80 ft-lb/in min. White colour is due to carbide formation. If you have any query regarding this article ask by commenting. This property data is a summary of similar materials in the MatWeb database for the category "Cast Iron". Thanks for reading it. It contain up to 2.3 percent carbon. It has Good casting properties; It is available in large quantities, hence produced in mass scale. Cast iron which have equal amount of free carbon and carbide known as mottled cast iron. Users requiring more precise data for scientific or engineering Underwater Welder Salary -How Much They Earn? The graphite can be induced to precipitate in a spheroidal shape by removing the sulphur from the melt using a small quantity of calcium carbide. endstream endobj startxref This metal is designate by FG followed by the digit show maximum tensile stress.

The recommended applied tensile stress is therefore only a quarter of its actual ultimate tensile strength. Cast iron having a tensile strength of 5 tons per square inch or less, and is of no significant value for purposes where the alloy is required to possess strength. The white cast iron has high tensile and low compressive strength therefore it cannot be machined.
