Mbemba Stainless is a trusted manufacturer and supplier located in Kinshasa, Congo, specializing in high-quality Stainless Steel 201 Tubing. These tubes are crafted from an austenitic chromium-nickel-manganese stainless steel, engineered to deliver impressive strength, good formability, and moderate corrosion resistance—all at a more affordable price. Mbemba Stainless takes pride in its precise manufacturing processes and rigorous quality control to ensure they meet international standards. Their Stainless Steel 201 tubing is perfect for a variety of industrial and structural applications, offering durability, reliability, and resistance to oxidation and wear in both indoor settings and moderately corrosive environments.
Stainless Steel 201 Tubing mainly consists of iron, along with 16–18% chromium, 3.5–5.5% nickel, and 5.5–7.5% manganese, plus small amounts of nitrogen and carbon. It boasts a tensile strength of around 515 MPa and good yield strength, along with excellent work-hardening capabilities. This alloy provides decent resistance to corrosion and oxidation, while also offering good toughness and ductility. Its lower nickel content compared to 304 makes it a more budget-friendly option, all while maintaining solid mechanical performance for moderate service conditions.
