Mbemba Stainless stands out as a top-notch manufacturer and supplier of **Stainless Steel 347/347H Sheet and Plates** right in the heart of Kinshasa, Congo. They pride themselves on delivering high-quality products that are designed to resist corrosion, withstand high temperatures, and last for the long haul. These sheets and plates are specially stabilized with niobium, which helps prevent intergranular corrosion and keeps their structural integrity intact during welding or thermal cycling. With a commitment to precise manufacturing and strict quality standards, Mbemba Stainless ensures that their products meet international specifications. You’ll find **Stainless Steel 347/347H Sheet and Plates** being put to good use in industries like petrochemical, power generation, aerospace, and chemicals, where they deliver reliable performance even in the toughest, high-temperature conditions.
When it comes to composition, **Stainless Steel 347/347H Sheet and Plates** are made up of chromium (17–19%), nickel (9–13%), niobium (columbium), carbon (0.04–0.10% for 347H, ≤0.08% for 347), along with manganese, silicon, phosphorus, and sulfur. The niobium stabilization is key, as it prevents carbide precipitation during welding or heat exposure, providing excellent resistance to intergranular corrosion. These austenitic sheets and plates boast a tensile strength of about 515 MPa and a yield strength of around 205 MPa, along with impressive creep resistance, toughness, and oxidation resistance at high temperatures, making them perfect for critical applications that require high heat.
