Kyaw Stainless is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializing in high-quality Stainless Steel 316L Flanges. These flanges are made from low-carbon austenitic stainless steel, which provides exceptional resistance to corrosion, particularly in chloride and acidic environments. The 316L grade is known for its excellent weldability and durability, even when exposed to high temperatures. At Kyaw Stainless, we produce flanges that adhere to international standards for precision, strength, and performance. Our Stainless Steel 316L Flanges are commonly used in industries that require dependable and leak-proof connections, making them perfect for applications in chemical processing, marine operations, and high-pressure fluid systems.
Stainless Steel 316L Flanges are made up of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), with a maximum carbon content of 0.03%. This specific composition enhances resistance to pitting, crevice corrosion, and general oxidation. The material boasts a tensile strength of about 485 MPa, a yield strength of 170 MPa, and an elongation of 40%, ensuring remarkable ductility and toughness. With a hardness of roughly 80 HRB, 316L flanges maintain their mechanical stability and corrosion resistance in environments with chlorides and high temperatures, guaranteeing long-lasting reliability.
