ASTM A240 Grade 321 SS Plates and Sheets Manufacturer, Supplier, Exporter & Stockist in india
ASTM A240 Grade 321 stainless steel plates and sheets are a popular choice in various industrial applications due to their excellent combination of mechanical properties and corrosion resistance. This austenitic stainless steel alloy is stabilized with titanium, which enhances its high-temperature capabilities. Here's a detailed overview of ASTM A240 Grade 321 SS Plates and Sheets: ASTM A240 Grade 321 is a type of austenitic stainless steel that adheres to the ASTM A240 specification, known for its remarkable resistance to high-temperature environments and exceptional corrosion resistance. This grade contains significant amounts of chromium and nickel, with chromium content ranging between 17% and 19% and nickel content between 9% and 12%. Additionally, manganese, silicon, and carbon are present in controlled amounts to facilitate specific mechanical and metallurgical properties.
One of the distinguishing features of Grade 321 is its titanium addition, which acts as a stabilizing element, preventing the formation of harmful chromium carbides during exposure to high temperatures. This makes Grade 321 well-suited for applications in elevated temperature settings, such as exhaust systems, furnace components, and aircraft exhaust stacks. Mechanically, ASTM A240 Grade 321 exhibits a tensile strength of at least 75 ksi (515 MPa) and a yield strength of a minimum of 30 ksi (205 MPa) with an elongation of 40% (in 2 inches). It has a Brinell hardness of up to 217 and a Rockwell B hardness of up to 95. The modulus of elasticity for Grade 321 is approximately 28.5 x 10^6 psi (197 GPa), and its Poisson's ratio is 0.3. The versatility of Grade 321 stainless steel is further emphasized by its excellent weldability, making it suitable for various fabrication processes. Its exceptional corrosion resistance extends to a wide range of corrosive environments, including organic acids, inorganic chemicals, and high-temperature water and steam.
