HY-80 is prone to the formation of martensite and martensite's peak hardness is dependent on its carbon content. HY-80 is an FCC material that allows carbon to more readily diffuse than in FCC materials such as austenitic stainless steel. Nickel – Adds to toughness and ductility to the HY-80 and is also an austenite stabilizer.
High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.
The development of such homogeneous steel resulted from testing which showed that face-hardened armor was less effective against high-obliquity glancing impacts. Around 1910, Carnegie Steel developed a new nickel-chrome-vanadium alloy-steel that offers improved protection over the prior nickel steel armor, though vanadium was no longer used ...
Although they used the same HY-80 steel (yield strength 80,000 psi (550 MPa)) as the Skipjacks, the Threshers ' pressure hulls were made using an improved design that extended test depth to 1,300 ft (400 m).
Also like Albacore, the Skipjacks used HY-80 high-strength steel, with a yield strength of 80,000 psi (550 MPa), although this was not initially used to increase the diving depth relative to other US submarines. HY-80 remained the standard submarine steel through the Los Angeles class. [5] Control room of Skipjack class; the bow is at the top.

Trump’s plan to eliminate taxes on Social Security benefits would help current beneficiaries, but future recipients may be hurt by the move.
MSM-1 USEL was the first submersible vehicle for underwater research and work of completely Italian conception. The basic design of MSM-1 USEL was done by ESCO of Milan.The pressure hull is made of HY-80 steel and subdivided in two compartments: a cylinder with hemispherical ends located aft, and a sphere forward, interconnected by a cylindrical tunnel.
