With the stronger HY-80 steel, this depth increased to 1,800 feet (550 m) and with HY-100 a depth of 2,250 feet (690 m). [2] The first production submarines to use HY-80 steel were the Permit class. These reportedly had a normal operating depth of 1,300 feet, roughly two-thirds the crush depth limit imposed by the steel. [2]

Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]
Sliding along crack tips leads to tensile forces along the tip of the crack. Microcracks tend to form around any pre-existing crack tips. In all cases it is the overall global compressive stress interacting with local microstructural anomalies to create local areas of tension. Microcracks can stem from a few factors.

7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
The original US 66 followed an east-west line across the Texas Panhandle from Glenrio, New Mexico and Texas to Texola, Oklahoma.When Interstate 40 (I-40) was constructed most of the highway was upgraded in place, reducing construction costs and keeping existing towns close to the new highway to minimize tourism losses.
Gray iron above class 40 requires alloying to provide solid solution strengthening, and heat treating is used to modify the matrix. Class 80 is the highest class available, but it is extremely brittle. [ 12 ]
