Abstract : This report documents the mechanical properties of steel plates for Navy use. These plates conform to American Society for Testing and Materials (ASTM) Standard A945, High-strength, Low-alloy (HSLA), Class 65. Plates of various thickness were purchased from two different producers to determine if the steel could be obtained on a production scale, as opposed to a custom order. Tensile and Charpy V-notch impact tests were performed on the steels, and the results are reported within. All of the plates met the minimum mechanical property requirements. The plates also met the minimum Charpy impact energy requirements. Future testing will include dynamic tear testing, static and dynamic fracture toughness testing. A plate supplied by a third producer will also be evaluated.
