Akor Stainless, located in Abuja, Nigeria, stands out as a top manufacturer and supplier of high-quality Stainless Steel 348H Bars. These bars are celebrated for their outstanding performance in both high-temperature and corrosive environments. With a strong focus on precision and durability, Akor Stainless guarantees that each bar adheres to international quality standards, offering dependable solutions for various industrial and engineering needs. Their Stainless Steel 348H Bars are designed for longevity, blending strength with remarkable resistance to oxidation and creep. Serving a wide range of sectors, Akor Stainless has earned a solid reputation for delivering products that can endure tough operational conditions while keeping their structural integrity intact.
The composition of Stainless Steel 348H Bars primarily includes iron, chromium (about 18–20%), nickel (roughly 9–12%), along with carefully controlled amounts of carbon, manganese, and silicon. The “H” grade signifies a higher carbon content, which enhances creep strength at elevated temperatures. These bars boast impressive mechanical properties, such as high tensile strength, superior yield strength, and exceptional creep resistance. They also maintain stability under extended exposure to high temperatures, providing excellent oxidation resistance and toughness. This specific composition ensures they perform reliably in critical applications where both strength and heat resistance are essential.
