The A872/A872M-14 steel grade is a standard specification for centrifugally cast ferritic/austenitic stainless steel pipe for corrosion-resistant applications. It is commonly used in applications where resistance to corrosion, high temperatures, and mechanical strength are required.
The chemical composition of A872/A872M-14 steel grade includes elements such as chromium, nickel, molybdenum, and manganese, which contribute to its corrosion resistance and high-temperature strength. The specific percentages of these elements may vary depending on the manufacturer and grade, but typically chromium content is around 20-24% and nickel content is around 6-9%.
The mechanical properties of A872/A872M-14 steel grade are determined through various tests, including tensile strength, yield strength, and elongation. The minimum tensile strength for this grade is 70,000 psi (485 MPa) and the minimum yield strength is 30,000 psi (205 MPa). The elongation is typically around 30%.
The A872/A872M-14 steel grade is widely used in industries such as chemical processing, oil and gas, power generation, and water treatment. It is preferred for applications where resistance to corrosion from various corrosive environments, including acids, alkaline solutions, and seawater, is crucial. Its high-temperature strength makes it suitable for use in high-temperature and high-pressure applications.
Overall, the A872/A872M-14 steel grade offers excellent mechanical and corrosion-resistant properties, which make it a reliable choice for various demanding applications in different industries.
