Known for their durability, high performance, and precise finish, these products are designed to meet a variety of industrial and commercial needs. Thanks to cutting-edge manufacturing techniques and rigorous quality control, Boikanyo guarantees that each sheet and plate adheres to international standards. Their Stainless Steel 348 offerings are highly regarded for their exceptional resistance to intergranular corrosion and impressive strength, making them perfect for demanding sectors like chemical processing, aerospace, and power generation.
Stainless Steel 348 Sheets and Plates are enhanced with columbium and tantalum, which boost their resistance to intergranular corrosion, especially after being exposed to high temperatures. This alloy typically includes chromium (17–19%), nickel (9–13%), and trace amounts of carbon, manganese, silicon, phosphorus, and sulfur. It boasts excellent mechanical properties, featuring a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa. With outstanding creep resistance and remarkable oxidation resistance up to 1500°F (816°C), Stainless Steel 348 is the go-to choice for high-temperature applications where stability and durability are essential.
