What is HY-80 steel? HY-80 is a high-performance, low alloy steel that includes small amounts of nickel and chromium. HY-80 is known for its combination of strength and toughness. It derives its name from its minimum yield strength of 80,000 pounds per square inch (psi). Manufacturers must be independently certified in HY-80 production.
The properties of HY-80 make it ideal for the naval defense market, including submarines and surface ships. HY-80’s high strength-to-weight ratio and toughness make it a good fit for structural applications, and its weldability allows the fabrication of complex structures and assemblies. While not a corrosion resistant as stainless steel, HY-80 stands up to the corrosive effects of saltwater.
MetalTek's Carondelet Division is certified to produce HY-80 metal castings up to eight (8) inches in thickness to Naval Sea Systems Command (NAVSEA) Technical Publication T9074. Carondelet is one of few manufacturers to offer HY-80 using the sand casting process.
