The spheroidization rate refers to the percentage of the total number of spherical graphite in a certain range to the total number of graphite. Inside the ductile cast iron by electron microsope, the shape of spheroidal graphite is approximately spherical, and its interior is radial shape, and it has obvious polarization effect. That is why the ductile cast iron is also called spheroidal graphite cast iron or nodular cast iron. As one of the widely used casting metals, cast gray iron has many advangates in costs, castability and machinablity.ĭuctile iron refers to cast iron in which the graphite is spherical after the molten iron is treated with a spheroidizing agent. During the grey iron, the Carbon is in the flake graphite. The metallographic structure of gray cast iron is mainly composed of flake graphite, metal matrix and grain boundary eutectic. Gray cast iron is a kind of iron-carbon alloy and it gets its name "grey" from the fact that their cutting sections looks grey. Grey cast iron (also called grey cast iron) is a group of cast iron including several kinds of grade according to different designation of diverse standards. As a global leader in high-precision, high-complexity, and mission-critical casting and machined components, we strive to meet and exceed the needs of our customers. ![]() RMC is dedicated to the quality of our work, and our commitment to excellence ensures the highest customer satisfaction. ![]() From start to finish, we have you covered every step of the way. We provide assembly, testing and qualification, heat treatment, and surface treatment. We also offer cavity fill, solidification, tension and distortion services. We do 3-D CAD drawings, simulations, and component machining. We offer material advisory service and development, as well as advice from our technical experts on design and casting. We use ultrasonic detectors to discover flaws, and have X-ray machines and accelerators that can scan castings with 200 mm maximum wall thickness. Our metallurgical microscope produces high-resolution images 1,000 times magnified, and our cleanliness meter determines particle size and quantity to ensure materials meet or exceed the international standard. Our Speck spectrometer checks 28 chemical elements. Our green sand castings range from 0.5 kgs to 1000 kgs We produce parts in low-to-high volumes and pour castings ranging from 0.5 kgs to 5 tons. In our high-tech facilities, we offer both machine and manual molding operations in our resin sand casting processes. RMC's experience in creating high-end sand castings from high-grade materials and consisting of complex geometries is beyond comparison. Gray Iron, Ductile Iron, Cast Steel, Stainless Steel, Al Alloys, Brass, Bronze.etc. RMC can produce casting parts in a wide variety of materials, including grey iron, ductile iron, stainless steel, carbon steel, wear-resistant steel, and heat-resistant steel based on different standards from China and overseas. RMC Casting Foundry can pour iron castings using our no-bake process (furan resin coated sand mold) up to ten tons finished weight in gray iron castings and ductile iron castings, and up to five tons in steel castings and stainless steel castings.
