Cl30,35,40 tensile and heat resistant irons. Gray Iron has a dense gray structure and offers excellent machinability. Gra 30, 35 and 40 can fill specific requirements for hardness and wear, and heat treatments can yield even higher mechanical properties. Popular applications for gray iron include diesel and gasoline engine blocks and cylinder liners, [ ]. Gray and Ductile Iron Foundries. These are some iron foundries specializing to produce gray and ductile iron castings. 1. Dandong Foundry Dandong Foundry is a professional iron foundry located in China. They have over 50 years experiences in iron casting, steel casting and machining fields. Main Products. Gray Iron Foundries General Iron foundries produce high-strength castings used in industrial machinery and heavy transportation equipment manufacturing. Castings include crusher jaws, railroad car wheels, and automotive and truck assemblies. Iron foundries cast 3 major types of iron: gray iron, ductile iron, and malleable iron File Size: KB. IQS Directory provides an extensive list of grey iron casting manufacturers and suppliers.

Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material based on weight. It is used for housings where the stiffness of the component is more important than its tensile strength, such as. As with all things, grey iron is only as good as the materials that are used to make it. Willman Industries only buys the best scrap and raw materials to produce our grey iron castings. We believe this is the key to our superior grey iron castings. The graphite level in grey iron is a very critical property that makes it a common engineering alloy. Grey iron – Flake graphite provides gray iron with unique properties (such as excellent machinability) at hardness levels that produce superior wear-resistant characteristics, the ability to resist galling and excellent vibration damping. Grey iron is sometimes spelled gray iron. Strength and hardness are sensitive to section thickness in gray iron castings. Saguenay Foundry casts parts in gray iron (or lamellar iron) weighting from lb to 16, lb ( kg to kg). For more information on gray iron properties, don’t hesitate and go to our Technical Center. Custom Gray Iron. We pour gray iron on a daily basis using a wide range of alloys to improve mechanical properties and thermal resistance.
