Chanchai Stainless is a reputable stainless steel manufacturer and supplier based in Bangkok, Thailand, known for its top-notch Stainless Steel 316L Flanges. These flanges are crafted for exceptional strength, durability, and outstanding resistance to corrosion. The 316L grade is a low-carbon version of 316 stainless steel, specifically designed to reduce carbide precipitation and improve weldability during fabrication and high-temperature applications. With remarkable resistance to pitting, crevice corrosion, and chemical attacks in environments rich in chlorides and acids, these flanges guarantee secure, leak-proof piping connections. Manufactured with precision and in line with international quality standards, Chanchai Stainless distributes 316L flanges widely across industries such as petrochemical, marine, pharmaceutical, food, and power generation.
Stainless Steel 316L Flanges are made up of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a lower carbon content that enhances weldability and reduces the risk of sensitization. This specific composition boosts their resistance to corrosion caused by chlorides, aggressive chemicals, and acidic conditions. In terms of mechanical properties, 316L flanges offer a tensile strength of about 485 MPa, a yield strength of 170 MPa, and excellent ductility, making them easy to machine and fabricate. They maintain their hardness, toughness, and resistance to oxidation even at high temperatures. With strong resistance to stress corrosion cracking, Stainless Steel 316L Flanges are reliable performers in demanding service conditions across critical industries.
