Cast Irons Specifications for Gray Iron and Ductile Irons

Aug 07, 2007 · Cast Irons Specifications for Gray Iron and Ductile Irons. Gray iron is the original and most common cast iron, so named because of its fracture surface which is typically dark gray in colour. Due to its high carbon content, it has flake graphite in its structure. The formation of the flakes or nodules of graphite can be suppressed in Class 40 Gray Iron Supplier Material Properties ASTM Specification:A 48 (Class 40) Our V-2 Class 40 Continuous Cast Gray Iron is a Better Alternative. V-2 (Class 40) gray iron features a tensile strength of 40,000 psi with a compression strength of 150,000 psi. Class 40 gray irons hardness ranges from 187 to 269 bhn. The microstructure is essentially pearlitic.

Gray iron consists of graphite flakes in a metallic matrix. When fractured, it is grayish in colour hence the name (specifically, a fracture will follow along the graphite flakes which are gray). The low cost of production and attractive properties make gray iron one of the most commonly used ferrous

Grey Cast Iron Properties Parts ASTM A48 No.35 Material

Grey Iron Classifications. In theUnited States, the most commonly used classification for gray iron is ASTM International standard A48. This orders gray iron into classes which corresponds with its minimum tensile strength in thousands of pounds per square inch (ksi); e.g. class 20 gray iron has a minimum tensile strength of 20,000 psi (140 MPa). Group of ASTM standards for steel castings and forgingsThis group of ASTM specifications covers standard properties of steel and iron castings and forgings for valves, flanges, fittings, and other pressure containing parts for high-temperature and low-temperature service.

grey cast iron composition - Sand Casting, Investment

Grey Cast Iron (Gray iron) is so called because of the colour of the fracture face. It contains 1.5-4.3% carbon and 0.3-5% silicon plus manganese, sulphur and phosphorus. It is brittle with low tensile strength, but is easy to cast. The all data in this documents is referred to Chinese standard of GB/T 9439-1988.
