The A995/A995M-13 steel grade is a specification for castings made from duplex stainless steel for various applications. It has excellent mechanical properties and offers good resistance to corrosion, making it suitable for use in industries such as oil and gas, chemical processing, and marine environments.
The chemical composition of A995/A995M-13 steel grade typically includes elements such as chromium, nickel, molybdenum, and nitrogen. These elements contribute to the steel’s high strength, excellent corrosion resistance, and good weldability. The exact composition may vary depending on the specific variant of A995/A995M-13 steel grade.
In terms of mechanical properties, A995/A995M-13 steel grade has a minimum yield strength of 65 ksi (450 MPa) and a minimum tensile strength of 90 ksi (620 MPa). It also has a minimum elongation of 25% and a minimum reduction in area of 45%. These properties ensure the steel grade can withstand high stress and exhibit good ductility.
A995/A995M-13 steel grade is commonly used in applications where a combination of high strength and corrosion resistance is required. This includes components such as valves, pumps, fittings, and other machinery parts operating in aggressive environments. The steel grade’s resistance to pitting, crevice corrosion, and stress corrosion cracking makes it particularly suitable for applications involving exposure to chloride-containing solutions.
The A995/A995M-13 steel grade conforms to the ASTM A995/A995M-13 standard. This standard specifies the requirements for castings made from duplex stainless steel and provides guidelines for chemical composition, mechanical properties, and heat treatment. Adhering to this standard ensures consistency and quality in the manufacturing and use of A995/A995M-13 steel grade castings.
Overall, the A995/A995M-13 steel grade offers a combination of high strength, corrosion resistance, and good weldability, making it suitable for a wide range of demanding applications in various industries. Its properties and adherence to standards make it a reliable choice for critical components that require durability and longevity.
