Large diameter ductile and gray iron bar stock.

[ILLUSTRATION OMITTED]

Continuous cast bar stock supplier Dura-Bar is now offering round bars in extra-large sizes--up to 25 in. in diameter. The new product line--Dura-Bar XL--is available in 65-45-12 ductile and G2 gray iron. Dura-Bar said the new extra-large bars are expected to expand its product range as an alternative to steel in the manufacture of large metal components.

Dura-Bar said XL is especially applicable for industrial equipment manufacturers as a replacement for carbon steel bar and traditional castings. Dura-Bar XL is also suited for producing molds as well as pattern and mounting plates, the Woodstock, Ill., company said.

Dura-Bar XL ingots are cast in permanent metal molds and are supplied rough-turned to a dimension of +0.125 in./-000 in. The rough turning further enhances the machin-ability of the product, the company said.

While differing somewhat from its traditional continuous casting, the permanent mold process used to produce XL uses the same quality melt stock and is subject to the same quality processes designed to virtually eliminate casting defects such as gas holes, inclusions and hard spots, Dura-Bar said.

For metal component manufacturers needing large-sized rectangles, Dura-Bar offers continuous cast rectangles up to 18.5 in. x 22 in. and 14 in. x 25 in. The company is expected to introduce even larger rectangles made by the permanent mold process in the near future.

In addition to its new XL sizes, Dura-Bar produces an array of smaller rounds, trepanned tubes, squares and rectangles in gray, ductile and Ni-resist irons. Special shapes also are available, the company said.
