Falk's Steel Castings Receive Navy Approval

The Falk Corp, Milwaukee, WI-based subsidiary of Sundstrand Corp, has been approved by Naval Sea Systems Command, Department of the Navy, as a supplier of steel castings for HY-80 MIL-S-23008D(SH) requirements. This certification allows Falk to bid on steel casting contracts involving a variety of Naval vessels.

HY-80 is a sturdy, lightweight grade of steel with a tensile yield strength of 80,000 lb/sq in. It is a low carbon, high alloy steel that is used for critical structural applications requiring a high strength, weldable material. The castings could be specified for a number of parts aboard ships and submarines.

Castings up to 32,000 lb can be poured with maximum sulfur and phosphorus levels at .008 and .014, respectively. Carbon, alloy and stainless steels complement the remainder of their capacity, with stainless casting weights reaching 35,000 lb and carbon and alloy steels being as high as 100,000 lb.

Falk's certification permits the waiving of "first article" test requirements, up to and including eight inch sections, and automatically qualifies the company to produce earlier revisions of this specification.

Falk is a major manufacturer of industrial power transmission machinery including standard and custom gear drives, flexible shaft couplings, backstops, fluid power drives and fluid couplings, as well as custom marine drives for various applications and custom metal castings.
