HY-80 is considered to have good corrosion resistance and has good formability to supplement being weldable. Using HY-80 steel requires careful consideration of the welding processes, filler metal selection and joint design to account for microstructure changes, distortion and stress concentration. Meer weergeven 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 … Meer weergeven The need to develop improved steels was driven by a desire for deeper-diving submarines. To avoid detection by sonar, submarines ideally operate at least 100 metres … Meer weergeven HY-80 steel can be welded without incident provided proper precautions are taken to avoid potential weldability issues. The fact that … Meer weergeven HY-80 steel is a member of the low carbon, low alloy family of steels with nickel, chromium and molybdenum (Ni-Cr-Mo) as alloying elements and is hardenable. The weldability of the steel is good, though it does come with a set of challenges due to the carbon … Meer weergeven The testing of HY-80 steel can be divided into the categories of destructive and non-destructive evaluation. A variety of destructive tests from Charpy V-notch to explosion bulge can be performed. Destructive testing is not practical for inspecting … Meer weergeven Web1 dec. 2006 · Temper embrittlement in HY-80 steel: Microstructure, magnetic and microhardness properties Jason Schibler, Charles D'Ambra, Michael Roberts, M.

Steel casting - Wikipedia
WebHigh-pressure tubing can be made from HY 100 and HY 80 bars up to 30 feet in length. Tubes can be welded together to achieve longer lengths. The material’s superior combination of ductility and fracture toughness makes it a great choice for pressures as high as 14,000 PSIG operating pressure or more depending on wall thickness. WebWithin this class, that includes HY-80, HY-100, HY-130 and HY-180, which are high strength and toughness, quenched and tempered, martensitic steels. The single materials are identified by the numbers that represent their yield strength, expressed in ksi (kilo or 1000 pounds per square inch).
