HY-80

Technical Information for HY-80 Steel

HY-80 is a high-tensile, high yield strength, low alloy steel. It was developed for use in naval applications, specifically the development of pressure hulls for the US nuclear submarine program and is still currently used in many naval applications. It is valued for its strength to weight ratio

The “HY” steels are designed to possess a high yield strength (strength in resisting permanent plastic deformation). HY-80 has a high yield strength with a minimum of 80 ksi.

A close-up view of a stack of shiny, cylindrical metal rods resting in a workshop. The rods, likely forged from fighter jet metals, are uniformly cut with smooth surfaces, arranged parallel to each other, and the background contains blurred machinery and workshop tools.

ROUND BAR

A stack of flat metal bars piled on top of each other. The bars, possibly crafted from fighter jet metals, are aligned horizontally, showcasing their thin, rectangular shape and metallic finish. The image highlights the texture and edges of the bars in close detail.

FLAT BAR

Close-up of several stacked aluminum sheets in an industrial setting. The smooth, reflective surfaces of the sheets are clearly visible, akin to the polished finish found in fighter jet metals. The edges show precision cuts, and the background includes blurred industrial equipment and shelving units.

PLATE

HY-80 Plate per MIL-S-16216 & NAVSEA T9074-BD-GIB-010/0300 Thickness ranges from 0.1875″ to 6.50″ Thick.
