![]() ![]() ![]() Other ASTM standards that deal with gray iron include ASTM A126, ASTM A278, and ASTM A319. ![]() Class 80 is the highest class available, but it is extremely brittle.ĪSTM A247 is also commonly used to describe the graphite structure. Gray iron above class 40 requires alloying to provide solid solution strengthening, and heat treating is used to modify the matrix. Higher-strength gray irons, up to class 40, have lower carbon equivalents and a pearlite matrix. class 20 gray iron has a minimum tensile strength of 20,000 psi (140 MPa).Ĭlass 20 has a high carbon equivalent and a ferrite matrix. These orders gray iron into classes that correspond with its minimum tensile strength in thousands of pounds per square inch (ksi) e.g. In the United States, the most commonly used classification for gray iron is ASTM International standard A48. The grey iron casting products are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, etc. Paint coating, electrophoretic paint coating, electro galvanizing coating, black oxide coating, phosphate treatment, powder coating, etc. Weight range: from 50 gram to 5,000 kilograms for ductile iron casting productĬNC machine, machining center, lathe, mill machine, drill machine, etc. It’s the metal of choice for some companies due to its lighter weight and impressive corrosion resistance, the latter factor being particularly significant for some industries.SAE G3000 Grey Iron Material Castings Foundry Manufacturer China The mineral is applied before the casting process to produce an impact-resistant, durable metal that can last for years. The presence of magnesium in ductile iron makes it the preferred choice for durable parts. Gray iron is known for the following properties: We recommend gray iron to companies looking for durable components. Gray iron is ideal for OEM (original equipment manufacturing), automotive, and aerospace applications. Castings made of gray iron use an alloy of 95% iron, 2.1 to 4% carbon, and 1 to 3% silicon. The name gray iron comes from the grayish hue that the metal exhibits after the casting process. We'll be happy to recommend the ideal type depending on your unique needs. Our team specializes in two types of iron castings: gray iron and ductile iron casting. We provide affordable and high-quality castings at Fountain Foundry. The alternatives are cold-setting materials like epoxy, concrete, plaster, and clay. Iron is by far the most popular metal that is being turned into parts by this method. While different materials can be ejected from or taken out of a mold, hot metals are the most common materials used. The casting can directly be used once cooled. The solidified metal is known as a casting, which is immediately removed off the mold once properly cooled. Iron casting is a manufacturing process that involves pouring molten material into a mold to take its shape. Through our gray and ductile iron casting services, customers can get quality metal parts that suit their specifications with quick turnaround times. Clients looking for quality metal parts can count on Fountain Foundry for quality components and products. ![]()
