The A572 standard is a steel standard for high-strength, low-alloy structural steels used in building structures and bridges. Details of the A572 standard are below:
1. Standard number: A572/A572M.
2. Material Classification: The standard covers five different grades of high-strength low-alloy structural steel.
3. Chemical Composition Requirements: The chemical composition requirements of steel vary by grade, but the general requirements are: carbon content of not more than 0.23%, manganese content of not more than 1.35%, silicon content of not more than 0.40%.
4. Mechanical properties: the mechanical properties of steel also vary according to different grades. Typical requirements include tensile strength, yield strength, elongation and so on.
5. Steel can be treated with rolling, normalising or normalising and tempering to get the right mechanical properties.
6. Marking and labelling: steel should be marked and labelled with the grade, manufacturer and other information.
The A572 standard specifies the chemical composition, mechanical properties and heat treatment requirements of high-strength low-alloy structural steels. These steels are commonly used in building structures and bridges.
