Mbemba Stainless is a reputable manufacturer and supplier located in Kinshasa, Congo, known for providing top-notch AWS Class ER347 SAW and FLUX welding consumables. These products are crafted to deliver outstanding corrosion resistance and maintain weld integrity. Specifically designed for submerged arc welding applications, they ensure strong, durable, and clean welds. Mbemba Stainless prides itself on precise manufacturing, consistent quality, and compliance with international standards. Their AWS Class ER347 SAW and FLUX are popular across various industries, including chemical processing, petrochemical, marine, and food processing, where resistance to intergranular corrosion, high-temperature stability, and long-lasting performance are crucial.
The AWS Class ER347 SAW and FLUX are mainly made up of chromium, nickel, and columbium (niobium), which help stabilize the alloy and prevent carbide precipitation during the welding process. This unique composition offers excellent resistance to intergranular corrosion and ensures mechanical integrity even at elevated temperatures. Typically, these materials boast a tensile strength of around 550 MPa, along with good ductility and toughness. The flux plays a vital role in enhancing arc stability, reducing spatter, and creating smooth, clean weld beads, resulting in crack-free, durable welds that resist oxidation and corrosion in tough environments.
