Continuous Casting Standard Grades and Process
American Iron and Alloys has a variety of continuous cast iron grades available. We offer years of knowledge in the industry to provide you with the exact grades for your specific application. If you don’t see the grade you are looking for below, don’t hesitate to give us a call. Our custom metal supply program options are endless.
Gray iron is preferred for producers looking for a low-cost option to produce custom continuous cast iron components with high density and strength. It is best used in vibration damping equipment such as blocks and frames for manufacturing equipment.
Gray iron is an excellent thermal conductor with good wear resistance, but is not very flexible, containing no recognizable elongation.It can survive approximately 2 foot-pounds of impact, featuring lower impact resistance than ductile iron (ductile iron can withstand around 7 foot-pounds of impact).
Ductile iron is a more flexible alloy, featuring more fatigue resistance and a higher impact resistance than its counterpart, gray iron. Instead of rod-like flakes, ductile iron bar is composed of graphite nodules making it flexible during solidification. Ductile iron molecules are more malleable and feature greater ductility—the ability of a metal to be shaped into wires.
Ductile iron stock is available for sale as a raw material for you to process and finish on your own, or we can finish and machine it into custom continuous cast iron components based on your exact requirements at our state-of-the-art CNC facility in Waukesha. It’s up to you. We provide you with high quality ductile iron in whatever form you desire.
V-2 Class 40 gray iron has a tensile strength of 40,000 psi with a compression strength of 150,000 psi. It's ideal for bearings, bushings & hydraulic components.Learn More
V-3 ductile iron has a tensile strength of 65,000 psi with a yield strength of 45,000 psi. It's fine ferritic structure makes it a very easily machinable material.Learn More
With a tensile strength of 80,000 psi and a yield strength of 55,000, V-4 ductile iron is a more efficient and affordable alternative to steel.Learn More
Gray and ductile continuous cast iron are two of the most dominant metals produced in the industry today. Ductile is often thought of to be an “upgraded” version of gray iron, but this outlook is sweeping and simplistic. Each has unique and distinguishable metallurgical characteristics to situate them strategically in the metal goods market. When considering what's best for your application, you must know the main differences between ductile and gray iron.
Frequently Asked Questions - Gray and Ductile Continuous Cast Iron
Continuous Casting Process for Versa-Bar Iron
Versa-Bar is manufactured using a continuous casting process, making it metallurgically superior to sand cast iron and other steel alternatives on the market. Continuous cast iron solidifies at a more uniform rate than sand cast iron, making it more durable. Learn about the advantages of the continuous casting and how your company saves money utilizing the remarkable process.
