Grade 40 is the ASTM designation for this material. In a particular size or type of casting, gray irons can also be satisfactorily designated by their Brinell hardness, (see Table 2). This designation has the advantage  Jan 24, 2014 Important mechanical properties for such castings are tensile strength, modulus of elasticity, impact strength and damping capacity. Gray cast iron  Taylor Fenn is a cast iron foundry in the USA that sets the standard for fast delivery of high quality gray iron and ductile iron castings. Dec 17, 2016 Gray cast iron is a type of iron with carbon content greater than 2% and a graphitic microstructure. It is one of the most common types of cast  A cast iron that gives a gray fracture due to the presence of flake graphite.

Cast Iron is widely used in machine / mechanical engineering, hydraulics, pneumatics, glass industry, automotive and mold making. Cast iron can be divided into two main groups: Grey/Flake Iron (EN-GJL / GG) and SG/Nodular Iron (EN-GJS / GGG). Grey cast iron is a broad term used for a number of cast irons whose microstructures are characterized by the presence of flake graphite in the ferrous matrix.

En grey cast iron

It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [1] It is the most common cast iron and the most widely used cast material based on weight. Grey Cast Iron EN-JL1020 and EN-GJL-150 These are the chemical composition, mechanical properties and equivalent grades of cast iron EN-JL1020 (EN-GJL-150), including its Tensile Strength, Elongation, Proof strength and Hardness. Chemical composition % of cast iron EN-JL1020 (EN-GJL-150): EN 1561-1997 EN-GJL-250 is a high material grade of grey cast iron in European standard EN 1561, it is also named as cast iron GG25 in standard DIN 1691 by Germany and Austria. The followings are its equivalent grades, chemical composition, mechanical properties, and some photos of grey iron castings made by Dandong Foundry.

In these materials the carbon content is higher than 2% and they are replenished with other elements like silicon and manganese. In comparison with steel casting , grey cast iron consumes less energy when melted, moreover it has a good castability and good shock absorbing characteristics. Description. Grey cast iron is a type of cast iron with lamellar graphite.

Malleable cast irons – Flake (grey), cast irons Malleable cast irons – Cast iron is the name given to those ferrous metals containing more than 1.7% carbon.Since the maximum amount of carbon which can be held in solid solution as austenite ( phase) is 1.7%, there will be excess carbon in all cast irons.This can be either taken up by the iron as cementite (combined carbon) or precipitated BS EN 1561:2011: Title: Founding.
