Chemical Composition: The chemical composition of A100-07(2012) steel grade is as follows:
– Carbon (C): 0.13% max
– Manganese (Mn): 1.50% max
– Phosphorus (P): 0.040% max
– Sulfur (S): 0.050% max
– Silicon (Si): 0.40% max
– Copper (Cu): 0.45% max
These chemical composition requirements ensure that the steel grade has the necessary properties for use in the building industry, such as strength, durability, and corrosion resistance.
Mechanical Properties: The mechanical properties of A100-07(2012) steel grade are as follows:
– Tensile Strength: 485 MPa (70,400 psi) minimum
– Yield Strength: 345 MPa (50,000 psi) minimum
– Elongation in 2 inches: 18% minimum
– Elongation in 8 inches: 22% minimum
– Brinell Hardness: 137 HBW average
These mechanical properties determine the strength and performance of the steel grade in structural applications. The high tensile and yield strength ensure that the steel can withstand the loads and stresses imposed on it during construction.
Standard Number: A100-07(2012) is a standard specification for carbon steel sheets and strip, structural quality, for the use in buildings. It is published and maintained by the American Society for Testing and Materials (ASTM). The standard provides requirements for the chemical composition and mechanical properties of the steel grade, as well as testing methods.
Corresponding Standard Number: There may not be a specific corresponding standard number for A100-07(2012) steel grade in other international standards. However, it is common for different countries or regions to have their own equivalent or similar specifications for similar steel grades. These specifications may differ in terms of chemical composition and mechanical properties, but the general purpose and application are usually similar. It is important to consult the relevant national or regional standards when using steel grades in different countries or regions to ensure compliance with local regulations and requirements.
