A767/A767M-16 is a standard specification for zinc-coated (galvanized) steel bars for concrete reinforcement. This specification covers the mechanical properties and chemical composition of the steel grade.
The mechanical properties specified in A767/A767M-16 include the yield strength, tensile strength, elongation, and bendability of the steel bars. The yield strength is the maximum amount of stress that the steel can withstand before it begins to deform permanently. The tensile strength is the maximum amount of stress that the steel can withstand before it breaks. The elongation is the measure of the steel’s ability to stretch without breaking. Bendability refers to the ability of the steel to be bent without cracking or breaking.
The chemical composition of A767/A767M-16 steel grade includes elements such as carbon, manganese, phosphorus, sulfur, copper, and silicon. The carbon content affects the strength and hardness of the steel. Manganese enhances the strength and toughness of the steel. Phosphorus and sulfur can improve machinability but may also reduce the steel’s ductility. Copper improves corrosion resistance, while silicon helps in deoxidation and improves the steel’s strength and toughness.
The standard number A767/A767M-16 refers to the specific version of the standard that outlines the requirements for zinc-coated steel bars for concrete reinforcement. It provides a comprehensive guide for understanding the steel grade and ensures consistency and quality in the manufacturing and use of these steel bars.
Overall, A767/A767M-16 provides important information on the mechanical properties and chemical composition of the steel grade, allowing engineers, manufacturers, and users to select and utilize the appropriate steel bars for concrete reinforcement applications.
