With a strong focus on delivering durable and dependable stainless steel products, the company serves industries that require exceptional resistance to corrosion, heat, and high-stress conditions. Stainless Steel 347 is enhanced with columbium, which provides outstanding resistance to intergranular corrosion, especially after being exposed to high temperatures. Boikanyo Sheets and Plates is dedicated to offering products that align with international standards, catering to clients in construction, chemical, power generation, and engineering sectors with unparalleled quality and performance.
Stainless Steel 347 Sheets and Plates are primarily made up of iron, 17–19% chromium, 9–13% nickel, along with small amounts of columbium/tantalum for superior stabilization. The alloy also includes controlled levels of carbon, manganese, silicon, phosphorus, and sulfur. It boasts a tensile strength of approximately 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%. With a melting range between 1398–1446°C, it exhibits excellent toughness, creep strength, and corrosion resistance. This specific composition ensures durability in high-temperature operations, making Stainless Steel 347 ideal for long-term use in challenging environments.
