V-1A ferritic gray iron for the glass mold industry

Class 25 Gray Iron Custom Cast Parts

Class 25 gray iron (25,000 psi) is used for many custom-cast parts.

Versa-Bar V-1A was initially developed for the glass mold industry, which requires a fine grain structure and a superior machining finish. Our continuous cast process results in an iron that is not only metallurgically superior to other steel alternatives but also more cost-effective.

Our V-1A gray iron comprises Type D graphite in a mostly ferrite matrix. The smaller graphite flakes and size and the ferritic matrix structure enhance ductility and result in healing and cooling cycles having little effect on dimensional growth. This makes it a favored choice for glass mold applications, such as blank molds and plungers.

Contact cast iron suppliers at American Iron for a quote on stock material or custom cast components.

While the high thermal conductivity of V-1A and its specific heat capacity make it ideal for decorative castings, the presence of graphite flakes and the excellent damping characteristics of this iron makes it also useful for applications involving wear, such as cutting tools and engine blocks. Versatility is a hallmark of Versa-Bar, and our customers find new applications daily.
