ASTM A653 SS Grade 50 & Grade 80
Standard Specification for Zinc-Coated (Galvanized) or Zinc-Iron Alloy Coated (Galvannealed) Steel Sheet by the Hot-Dip Process (A653/A653M).
Standard Specification for Zinc-Coated (Galvanized) or Zinc-Iron Alloy Coated (Galvannealed) Steel Sheet by the Hot-Dip Process (A653/A653M). This specification covers zinc-coated (galvanised) or zinc-iron alloy-coated (galvannealed) steel sheet in coils and cut lengths produced by the hot-dip technique. The American Society for Testing and Materials Standards is an acronym for the American Society for Testing and Materials Standards. One of its branch standard numbers is A-653. The standard for hot-dipped galvanised iron alloy or galvanised steel sheets is ASTM A653.
ASTM A653 Advantages
Hot-dip galvanised thin-coated materials provide good welding and processing capabilities. It can be used for a variety of purposes, ranging from casual use to detailed drawing.
Corrosion resistance is strong in thick galvanised hot-dip galvanised materials. By selecting spangles and post-processing functions, you can employ a variety of applications.
Hot-dip alloy steel offers great corrosion resistance as well as outstanding coating adhesion and ductility, allowing it to perform well in processing. It has the advantage of having a lovely appearance and being able to be employed in applications where the surface is not painted.
ASTM A653 Classification
• The following are the several designations for the material:
Commercial steel (CS Types A, B, and C), Forming steel (FS Types A and B), Deep drawing steel (DDS), Extra deep drawing steel (EDDS), Structural steel (SS), High strength low alloy steel (HSLAS Type A), and High strength low alloy steel (HSLAS Type B) are all examples of high strength low alloy steel (HSLAS Type B).
