Alu-zinc Alloy Coated Steel Sheet & Coil (...

ASTM A792 / A792M-097 Standard Specification for Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot Dip Process> Scope This specification covers 55% aluminum-zinc alloy- coated steel sheet in coils and cut lengths. This product is intended for applications requiring corrosion resistance or heat resistance, or both. This product is produced in a number of designations, types, and grades which are designed to be compatible with differing application requirements. Terminology Definitions-See Terminology A902 for definitions of general terminology relating to metallic-coated hot-dip products. Definition of Term Specific to This Standard. Regular spangle-the unaltered 55% aluminum-zinc(Al-Zn) crystal structure that occurs during normal solidification of a hot-dip coated steel sheet. Classification The material is available in several designations, as follows; Commercial Steel-CS Type A, B, and C, Forming Steel-FS Drawing Steel-DS High Temperature Steel-HTS, and} Structural Steel-SS. Structural steel is available in several grades based on yield strengths and tensile strength. The product is available in several coating weights [masses]with the coating designation.
