The chemical composition of A20/A20M-17 steel grade refers to the proportions of different elements present in the steel. This grade of steel primarily consists of carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), and copper (Cu). The specific percentages of each element may vary, but typically, A20/A20M-17 steel grade contains around 0.25% carbon, 0.6-0.9% manganese, 0.03% phosphorus, 0.03% sulfur, 0.15-0.35% silicon, and traces of copper.
The mechanical properties of A20/A20M-17 steel grade refer to its ability to resist various forms of stress and deformation. These properties include tensile strength, yield strength, elongation, impact resistance, and hardness. A20/A20M-17 steel grade typically has a high tensile strength of around 70,000-90,000 psi and a yield strength of about 45,000-60,000 psi. It also exhibits good elongation, impact resistance, and hardness properties.
A20/A20M-17 is the standard number assigned to this particular steel grade. The A20/A20M part indicates that the steel grade is specified in the ASTM A20/A20M standard, which covers a range of general requirements for steel plates, shapes, sheet piling, and bars for structural use.
