The A1049/A1049M-10(2015) steel grade is a standard specification for structural plates, sheet, and bars made of hot-rolled alloy steel with improved atmospheric corrosion resistance. Here are some key characteristics of this steel grade:
– Chemical Composition: The steel is primarily composed of iron (Fe) as the base metal, with addition of various alloying elements such as copper (Cu), manganese (Mn), phosphorous (P), sulfur (S), chromium (Cr), nickel (Ni), and silicon (Si). The specific composition requirements are outlined in the standard.
– Mechanical Properties: The A1049/A1049M-10(2015) steel grade has specified mechanical properties that include yield strength, tensile strength, and elongation. These properties determine the strength and ductility of the steel, making it suitable for structural applications.
– Standard Number: A1049/A1049M-10(2015) is the standard number that identifies the specific edition of the ASTM International standard for this steel grade. The standard provides detailed requirements for the chemical composition, mechanical properties, heat treatment, and dimensional tolerances of the steel products.
– Corresponding Grades: The A1049/A1049M-10(2015) steel grade may have equivalent grades in other international standards. These corresponding grades signify that the steel meets similar chemical composition and mechanical property requirements as specified in the ASTM standard.
It is important to refer to the complete standard specification for A1049/A1049M-10(2015) to obtain comprehensive information about the steel grade, including specific composition limits, heat treatment requirements, and additional testing or certification requirements.
