Our V-2 Class 40 Continuous Cast Gray Iron is a Better Alternative
V-2 (Class 40) gray iron features a tensile strength of 40,000 psi with a compression strength of 150,000 psi. Class 40 gray iron’s hardness ranges from 187 to 269 bhn. The microstructure is essentially pearlitic. It’s used widely for bearing and bushing applications in the hydraulics industry.
But that’s not all it’s good for—class 40 gray iron is suited well for any high wear resistance applications within the limits of the available shapes and sizes. We also offer custom cast parts and in-house CNC machining services to support lean operations. All grades of continuous cast iron, including Class 40 gray iron, are excellent alternatives to steel. Our continuous casting process solidifies iron at a more uniform rate than sand-cast iron or steel.
The unique characteristics of Versa-Bar make V-2 class 40 gray iron a superior option to gray iron provided by many other distributors of raw cast iron stock and custom components.
American Iron, LLC has been shipping our gray iron rods and rounds around the United States for years. Our customers are companies who order custom continuous cast rods for their various manufacturing and assembling productions. Need the best prices on custom-cut ductile iron? We’re the company to call.

Versa-Bar Continuous Cast Iron Means Improved Performance
Why choose Versa-Bar V-2 gray iron? Versa-Bar contains a high graphite flake content giving it numerous benefits over other gray iron on the market. Microscopic graphite flakes have very small recesses promoting the retention of oil. Lubricated parts stay oily longer. In the event of oil loss, versa-bar is able to retain its lubrication, and it has a better chance of survival.
What does this all mean? Greater durability. Longer life. A better product for a better price.
V-2 Class 40 gray continuous cast iron beats aluminum, bronze, and steel in-field comparison testing.
The chart below shows speeds and feeds to aluminum, bronze, steel, and Class 40 Versa-Bar gray iron. Operators were asked to reach optimum surface feed per minute (SFM) on the Versa-Bar and maintain the comparable depth of cut and surface roughness with aluminum, bronze, and steel. All tests were done on conventional tooling and equipment.
As you can see, the V-2 grey iron beat the recommendations of conventional machinist handbooks for SFM on cast iron.
