What Is HY-80 Steel?

HY-80 is a high-performance, low alloy steel with small amounts of nickel and chromium.  HY-80 is known for its strength and toughness.  It derives its name from its minimum yield strength of 80,000 pounds per square inch (psi).  Manufacturers are independently certified in HY-80 production.

HY-80's properties make it ideal for the naval defense market, including submarines and surface ships.  HY-80’s high strength-to-weight ratio and toughness are a good fit for structural applications, and its weldability allows fabrication of complex structures and assemblies.  While not a corrosion resistant as stainless steel, HY-80 stands up to the effects of saltwater.

What Are The Benefits Of HY-80?

Benefits of HY-80 steel include:

  • High strength: HY-80's exceptional minimum yield strength of 80,000 psi allows it to withstand heavy loads without permanent deformation.

  • Toughness: HY-80 absorbs energy and without fracturing, critical for applications subject to dynamic loading and impact such as naval vessels.

  • Weldability: HY-80 can be fabricated into complex structures and assemblies without sacrificing its strong mechanical properties.

  • Corrosion resistance:  HY-80 exhibits good resistance to corrosion, including saltwater environments.
