The A435/A435M-17 is a standard specification for straight-beam ultrasonic examination of steel plates. This standard covers the procedure and acceptance standards for the examination of steel plates using ultrasonic testing.
The chemical composition of A435/A435M-17 steel grade varies depending on the specific grade being examined. Generally, it contains iron (Fe) as the main element, along with carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), and sometimes small amounts of other elements such as chromium (Cr), nickel (Ni), and copper (Cu).
The mechanical properties of A435/A435M-17 steel grade are determined by its chemical composition and the heat treatment it undergoes. The most important mechanical properties of steel include tensile strength, yield strength, elongation, impact toughness, and hardness. These properties determine how the steel will perform in different applications and under different loading conditions.
The A435/A435M-17 standard provides guidelines for the examination of steel plates, including the equipment and procedures used for ultrasonic testing. The acceptance criteria are specified in terms of the size and location of discontinuities detected during the examination.
In summary, the A435/A435M-17 steel grade is a specification for the ultrasonic examination of steel plates. It covers the chemical composition and mechanical properties of the steel, as well as the procedures and acceptance criteria for the examination.
