Mbemba Stainless is a reliable manufacturer and supplier located in Kinshasa, Congo, specializing in high-quality Stainless Steel 202 Flanges. These flanges are crafted from a durable austenitic chromium-nickel-manganese stainless steel, which offers impressive strength, toughness, and decent corrosion resistance—all at a competitive price. At Mbemba Stainless, they prioritize precision engineering, consistent quality, and compliance with international standards. Their Stainless Steel 202 flanges are perfect for a variety of industrial and structural applications, ensuring secure, leak-proof connections in piping systems across sectors like chemical processing, food production, construction, and general engineering.
The composition of Stainless Steel 202 Flanges includes iron, 16–18% chromium, 4–6% nickel, and 7.5–10% manganese, along with trace amounts of carbon and nitrogen. This blend results in a tensile strength of about 515 MPa, along with good yield strength, toughness, and ductility. They provide satisfactory corrosion resistance in mild environments and maintain solid mechanical properties even under moderate temperature and pressure. With their lower nickel content, they serve as a cost-effective yet robust alternative to 304 stainless steel.
