Alloy steel plates are steels that are alloyed with various elements like chromium, molybdenum, nickel, manganese, silicon, and vanadium to improve their mechanical properties. Different grades are designed for specific applications like high-temperature service, pressure vessels, structural use, and wear resistance.

Notes:
Class 1 vs Class 2: In plates like A387, Class 2 generally has higher strength than Class 1.
Heat Treatment: Many alloy steel plates are supplied normalized, quenched, and tempered to achieve the desired properties.
Standards: ASTM (American Society for Testing and Materials) and ASME (American Society of Mechanical Engineers) are the two main standard organizations.
