Harsh Metalloys, based in Mumbai, India, stands out as a top manufacturer and supplier of high-quality Stainless Steel 304L Flanges. Our 304L flanges are crafted for outstanding corrosion resistance and weldability, making them a popular choice across various industries, including chemical processing, pharmaceuticals, food and beverage, and water treatment. As a low-carbon version of SS 304, 304L provides improved resistance to intergranular corrosion, particularly after welding. At Harsh Metalloys, we guarantee that all our flanges comply with international standards like ASTM, ANSI, and ASME, and we offer a range of types, such as slip-on, weld neck, blind, and threaded, to cater to specific application requirements.
Stainless Steel 304L Flanges boast a well-balanced chemical composition that ensures excellent corrosion resistance and strength. Key elements include Chromium (18–20%), Nickel (8–12%), Carbon (≤0.03%), Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). Their mechanical properties feature a tensile strength of at least 485 MPa, yield strength of at least 170 MPa, elongation of 40% or more, and hardness of no more than 92 HRB. The lower carbon content not only enhances weldability but also reduces the risk of sensitization, making 304L flanges ideal for corrosive and high-temperature environments while ensuring they maintain their structural integrity and longevity.
