Cast Iron Class 40

 

Cast iron possesses the highest strength, hardness, resistance to wear and heat treating response for an unalloyed gray iron. Machinability, noise and vibration damping is Excellent to Very Good. Continuous casting virtually eliminates rejections due to porosity and centerline shrinkage.

Typical Applications
●Hydraulic cylinders
●Manifolds
●Bushings
●Bearings

Our foundry cuts material to the specifications provided by its customers through one of the many machines on hand. Our precision plate saws, bar saws, shears, and water jets have the ability to deliver your exact needs.
