What is ASTM B443?
ASTM B443 is a standard specification for nickel-chromium-molybdenum-niobium and nickel-chromium-molybdenum-silicon alloy plates, sheets, and strips. It specifies their chemical composition, mechanical properties, and permissible tolerances, and is used in the manufacture of high-performance metal products for use in harsh environments, such as Inconel 625 alloy..
What is ASTM B443 UNS N06625 Annealed Alloy Plate?
ASTM B443 UNS N06625 annealed alloy plate refers to a UNS N06625 nickel-based alloy plate (Grade 1) manufactured to ASTM B443 standards, which has undergone annealing at a minimum of 871°C (1600°F) followed by rapid cooling.
GNEE supplies ASTM B443 UNS N06625 annealed plates with a minimum tensile strength of 827 MPa and a minimum 0.2% yield strength of 414 MPa for cold-rolled sheets and strips, while hot-rolled plates (up to 70 mm thick) have a minimum tensile strength of 758 MPa and a minimum yield strength of 379 MPa. All specifications have a minimum elongation of 30%. Suitable for use in environments up to 593°C (1100°F), it exhibits excellent resistance to chloride corrosion and strong corrosive chemicals, and possesses good ductility and formability. Therefore, it is widely used in marine engineering, chemical industry, and other fields requiring reliable corrosion resistance and ease of processing.
