According to the carbon percentage, cooling condition, alloying element, heat treatment etc. 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). Uses include electrical fittings, hand tools, pipe fittings, washers, brackets, fence fittings etc. Low Tensile Strength. It contains 3 to 3.5 percentile carbon and rest iron. This results into low cost of its products. Tools required for casting process are relatively cheap and inexpensive. HC27 HIGH CHROME WHITE IRON. Sulphur in cast irons is known to favour the formation of graphite flakes. Underwater Welder Salary -How Much They Earn? This cast iron is produce to get desire properties of cast iron. calculations can click on the property value to see the original value as well as raw conversions to equivalent units. Tensile Strength 82.5 KSI min. It has Good casting properties; It is available in large quantities, hence produced in mass scale. Cast iron is ferrous carbon alloys which contain 1.7 to 4.5 percent carbon in either free or combine form. This metal is designate by FG followed by the digit show maximum tensile stress. This cast iron has low tensile strength, high compressive strength and no ductility. Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "Cast Iron". 3. It has high strength.

Tensile strength is the most important physical property for iron castings. Wear surfaces (impeller and volute) of slurry pumps. Cast iron which contain carbon in free form, known as Gray cast iron. Iron. 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. %%EOF It has improved strength and ductility like steel but can be cast easily. Cementite is the hardest element of iron and it causes quick cooling of the molten iron.
