Victor Sheets and Plates, a well-respected manufacturer and supplier located in Abuja, Nigeria, specializes in top-notch Stainless Steel 347 Sheets and Plates that are engineered for outstanding performance in high-temperature and corrosive settings. These sheets and plates are enhanced with niobium (columbium), which gives them remarkable resistance to intergranular corrosion and helps prevent carbide precipitation during welding. Renowned for their strength, durability, and resistance to oxidation, 347 stainless steel sheets are perfect for applications that require reliability in extreme conditions. Victor is committed to precision manufacturing and upholding international standards, making their 347 Sheets and Plates a reliable choice for the chemical, petrochemical, and aerospace sectors.
Stainless Steel 347 consists of about 17–19% chromium, 9–13% nickel, 0.45–1% niobium (columbium), with carbon levels reaching up to 0.08%, and manganese up to 2%. This alloy boasts a tensile strength ranging from 515–690 MPa, a yield strength of around 205 MPa, and an elongation of 40%, ensuring remarkable toughness and ductility. It can withstand oxidation up to 870°C (1600°F) and resists intergranular corrosion in the chromium carbide precipitation range. These characteristics make 347 stainless steel an excellent choice for high-temperature applications where welding and long-term stability are essential.
