Sadiki Metals, located in Kinshasa, Congo, has built a solid reputation as a reliable manufacturer and supplier of high-quality stainless steel products, including Stainless Steel 347 Hex Bars. Renowned for their durability, exceptional performance, and precision engineering, these hex bars are designed to meet the rigorous demands of various industries. Stainless Steel 347 is particularly valued for its outstanding resistance to corrosion and its ability to withstand high temperatures, making it a top choice for critical applications in the chemical, petrochemical, and power generation sectors. At Sadiki Metals, every hex bar is crafted to ensure consistent quality, superior mechanical performance, and reliability, positioning the company as a trusted partner for clients seeking long-lasting stainless steel solutions.
Stainless Steel 347 Hex Bars are made from an austenitic stainless steel alloy that contains 17–19% chromium, 9–13% nickel, and is stabilized with niobium (0.5–1.0%) to prevent intergranular corrosion. They typically feature a low carbon content (≤0.08%) to improve weldability. These hex bars boast a tensile strength of about 515–750 MPa and a yield strength ranging from 205–275 MPa, along with impressive elongation (40% or more). The material is known for its excellent resistance to oxidation, intergranular corrosion, and scaling at high temperatures, ensuring reliable performance in demanding, high-stress environments.

SS 347 Hex Bars are widely used in aerospace, chemical processing, and power generation for applications requiring high-temperature resistance, corrosion resistance, and strength. They outperform other grades due to their niobium stabilization, preventing carbide precipitation and ensuring durability.
SS 347 Hex Bars typically exhibit a tensile strength of 515-750 MPa, a yield strength of 205 MPa, and an elongation of 40% minimum. These properties ensure high durability, flexibility, and performance in demanding applications.
SS 347 Hex Bars commonly comply with standards like ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications ensure quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, meeting stringent safety and reliability requirements.
Stainless Steel 347 Hex Bars find extensive use in industries that require both corrosion resistance and high-temperature performance. They are commonly utilized in chemical processing equipment, heat exchangers, furnace components, turbine parts, and boiler systems. Additional applications include aerospace components, petrochemical machinery, and structural elements exposed to harsh conditions. The alloy’s stability at elevated temperatures and its resistance to intergranular corrosion make it particularly suitable for power plants, refineries, and other industrial settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
