ring only to the binary Fe-Fe3C or iron-graphite system, cast iron can be defined as an iron-carbon alloy with more than 2% C. The reader is cau-tioned that silicon and other alloying elements may considerably change the maximum solubil-ity of carbon in austenite (y). Therefore, in excep-tional cases, alloys with less than 2% C can solid-

By definition, steel is a combination of iron with a small amount of carbon. Thousands of products having various chemical composition, forms, and sizes are made of iron and steel by casting, forging, and rolling processes. Iron and steel comprise about 95 percent of all the tonnage of metal produced annually in the United States and the world.
diate mechanical working. Steel castings are near net shape prod ucts. Although cast steel accounts for only 10% of the total foundry industry sales, steel castings are used for vitally important compo nents in the mining, railroad, truck, construction, military, and oil and gas industries. The total capacity of the steel casting industry in
SG Iron is a type of cast iron that has been treated while molten with an element such as magnesium or cerium to induce the formation of free graphite as nodules or spherulites. The followings are the grade requirement to the chemical components and physical properties, and also grade comparison chart.

Iron and steel scrap is a vital raw material for the production of new steel and cast-iron products. The steelmaking and foundry industries in the United States are highly dependent upon the ready availability of scrap from manufacturing operations and from the recovery of products that are no longer used or needed. The steel industry has been recycling steel scrap for

Download our Cast Steel Grade Chart; Cast steel grades. Steel grades have been created by standards organizations such as ASTM International, the American Iron and Steel Institute, and the Society of Automotive Engineers to classify steels with specific chemical compositions and resulting physical properties. Foundries may develop their own internal grades of steel to meet user demand for ...

Ductile Iron vs Steel Posted by Penticton Foundry on November 5, 2015 Which Alloy is Better? Ductile Iron vs Steel. As we've already compared ductile iron castings to gray iron castings we thought we'd compare ductile iron and cast steel across a variety of properties to help determine which alloy is better for a given application. This blog is a simple, generic overview.
These castings are rolled to the required dimensions by the rolling mill to produce steel products. The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and ...
Both Cast iron and Cast steel are ferrous products containing iron and carbon as the major components. Cast iron is a ferrous material containing more than 2% carbon. On the other hand, Cast steel contains less than 2% carbon. So composition-wise the main difference is the amount of carbon present in cast iron and steel.

Carbon and low alloy steel castings are used in parts for railroad cars, pumps and valves, heavy trucks, construction and mining equipment, and power generation equipment. Good applications utilize the performance of steel with the flexible geometry of a casting. Steel castings offer high mechanical properties over a wide range of operating

The microstructures of iron and steels is complicated and diverse which is influenced by composition, homogeneity, heat treatment, processing and section size. Microstructure of castings looks different than those of the wrought products even if the composition is same and even if the same heat treatment is given. Pure iron is polymorphic.
Strength is a critical factor in metal uses, for example, some applications require stronger aluminum parts, while some products need high steel hardness or yield strength of steel, this may determine the selection of CNC machining material or product design. Here we collect the metal strength chart (tensile, yield strength, hardness, and density included) and mechanical properties chart of ...
Investment Casting vs. Stamping. Metal stamping is a more primitive metal shaping method. Metal stamping is performed when a sheet or strip of metal is delivered into a hydraulic or mechanical press which uses a die and high pressure to shape the metal fabrication into the desired parts.
