WebNaval components fabricated from HY-80 high-strength steels require an expensive preheat during welding to avoid heat-affected zone (HAZ) cracking. Quenched-and-tempered low-C, high-Ni steels were evaluated as potential alternatives to HY-80 steel castings with section sizes of 230 to 300 mm thickness. 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 … 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 … Meer weergeven The testing of HY-80 steel can be divided into the categories of destructive and non-destructive evaluation.
