A more flexible & durable 100 psi cast iron - Versa-Bar V-5 (HT) 100-70-03 Ductile Iron

With a minimal tensile strength of 100 psi and a minimal yield strength of 70,000 psi, our V-5 ductile iron stock is well-suited for the production of automotive parts, machinery, pump and compressor components, equipment for steel mills, and other heavy-duty industrial applications.

Versa-Bar continuous cast iron is not only metallurgically superior to steel, it is also more cost-effective than any other steel alternative. Our casting process solidifies the iron at a more uniform rate than sand cast iron, so it is more durable and reliable. With less scrap produced in the manufacturing process and less machining required, Versa-Bar also costs less.

100-70-03 ductile iron combines nodular graphite in a matrix of pearlite with a small amount of ferrite. It can be produced in a wide range of sizes and shapes, and is often used in place of plain carbon steel. Its machinability is similar to carbon steel, which can dramatically lower costs for parts requiring a lot of machining.
