At Frazer & Jones we melt and pour various grades of Malleable and Ductile iron to meet our customers’ requirements in relation to performance. These grades of iron conform to ASTM standards and are defined below. We are capable of making revisions to the current grades offered if the level of business warrants:

Malleable Iron
In addition to ductile iron, our foundry produces ferritic, martensitic, and pearlitic grades of malleable iron and has a net casting capacity of 15,000 tons. We offer the level of expertise that comes with over 150 years of foundry operation. Illustrated are typical castings that Frazer & Jones routinely produces to ASTM specifications.
