Our Class 40 Continuous Cast Gray Iron is a Better Alternative

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.

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.

Class 40 Gray Iron Machining Services:

Class 40 gray iron is appropriate for many types of machinery, including housings, pulleys, sheaves and spindles. It’s also used in the transportation industry, good for brake rotors, valve seat inserts and gears.

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.

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.
