Alloy steel A387 Grade 22 sheet is a heat-resistant chromium, molybdenum, manganese and nickel alloy, which strengthens from adding other elements like carbon. It contains a higher percentage of chromium, providing excellent corrosion resistance and increased temperature resistance to oxidation at high temperatures. Additionally, it has a moderate amount of molybdenum that increases overall strength and provides greater fracture toughness against impact loads. Furthermore, these alterations are complemented by adding small amounts of manganese and nickel for improved toughness and corrosion resistance. Lastly, even more, strength is added with the inclusion of a small number of carbon cements the other components together. Combining all the elements in Alloy steel A387 Grade 22 makes it an incredibly versatile material used in many industries worldwide.
A387-Gr22 Alloy steel sheet is a popular choice in industrial settings and construction due to its extensive list of uses and properties. Its chromium and molybdenum content are important factors that give it excellent heat resistance, making it ideal for higher temperature applications than other alloy steels. This sheet also improves mechanical strength compared with other steel forms, allowing it to be used as reinforcement in certain parts, such as pressure vessels. It is often employed in challenging environments due to its corrosion resistance - one example being nuclear power plants where this steel form can be seen providing reliable usage. Finally, this alloy exhibits high tensile strength, allowing it to be formed into intricate shapes while remaining strong enough even under extreme stress and tension.
The pressure rating of Alloy Steel A387 GR 22 Sheet is up to 50,000 psi and its maximum temperature is 1,100°F (593°C).
No, Alloy Steel A387 GR 22 Sheet does not corrode easily. It has excellent corrosion resistance due to its alloyed steel composition.
The appropriate welding technique for Alloy Steel A387 GR 22 Sheet is SMAW (Shielded Metal Arc Welding) or GTAW (Gas Tungsten Arc Welding).
