Multi-Stage Pump:

Material – ASTM A487, Grade CA6NM, Class A

A 12 stage split case pump is made up of three different castings: upper casing, impeller, and a lower pump casing. The parts are cast in martensitic stainless steel, which provides mechanical strength and superior corrosion resistance to endure the conditions of the nuclear environment.

2” Ball Valve Body

Material – ASTM B369, Grade C96400 (Cu-Ni 70/30)

Above is a high-pressure marine and NAVSEA application fluid delivery system component. SF&E will fully machine this item for our customer. We have strong expertise in casting valve bodies and other pressure retaining shapes to high specification applications.

Triple Offset Butterfly Valve Body Housing and Machined component

Material – ASTM A351, Grade CF3M (AISI 316L)

High specification, high criticality machined components, like the high-pressure fluid control valve above, can go through full non-destructive testing (NDT) evaluation if required.

Certified personnel are available on-site or from our high specification approved providers.

Supporting the Global Defense Supply Chain

All major weapons systems contain a metal casting. Stainless Foundry & Engineering works with different alloys and techniques to produce castings that are better equipped to support the defense industry needs, anywhere from submarines to advanced weapons systems.

High Spec Castings – What You Need to Know about Testing

Parts produced for the nuclear, petrochemical, power generation, military, and defense industries require a high level of specification. Thorough testing is imperative to ensure these critical castings not only meet customer and industry standards, but they have the structural integrity to perform throughout their expected service life. Here’s how we do it.

Anatomy of a Pour: Investment Casting Photo Story

When Stainless Foundry & Engineering (SF&E) opened its doors in 1946, we specialized in sand casting, primarily producing impellers for pumps. SF&E added investment casting to its service offering in 1968 in response to the increasing demand for precision parts. We’ve documented our investment casting process in a series of photos as a way to pay homage to this practice, which dates back to 3,000 B.C.
