The chemical composition of A285/A285M-17 steel grade complies with the requirements specified in the ASTM A285/A285M standard. This steel grade is typically composed of carbon (0.17% max), manganese (0.90% max), phosphorus (0.035% max), sulfur (0.035% max), and silicon (0.035% max). It may also contain trace amounts of other elements such as nickel, chromium, copper, and molybdenum.
The mechanical properties of A285/A285M-17 steel grade are also defined by the ASTM A285/A285M standard. The tensile strength of this steel grade is typically in the range of 55,000 to 75,000 psi (380 to 515 MPa), while the yield strength is usually in the range of 30,000 to 45,000 psi (205 to 310 MPa). The elongation at break is typically around 27%.
A285/A285M-17 steel grade is commonly used in the fabrication of pressure vessels and boilers. Its moderate strength and good weldability make it suitable for applications in the oil, gas, and petrochemical industries. This steel grade is also used in the construction of storage tanks, heat exchangers, and other high-pressure equipment.
Overall, A285/A285M-17 steel grade offers a balance of properties that make it ideal for applications where strength, weldability, and resistance to high-pressure environments are important considerations. With its wide range of applications and reliable mechanical properties, it is commonly chosen by engineers and designers in various industries.
