Yoane Steel is a reputable manufacturer and supplier located in Kinshasa, Congo, specializing in top-notch SA 515 Grade 70 Sheets and Plates. This company has built a solid reputation for delivering durable, heat-resistant, and pressure-bearing steel products that are perfect for various industrial applications. With a strong emphasis on precision engineering, Yoane Steel guarantees that each sheet and plate adheres to global standards for strength and reliability. Their products are crafted for outstanding performance even under high pressure and temperature, making them the go-to choice for industries like boiler, pressure vessel, and fabrication that require exceptional toughness and durability.
SA 515 Grade 70 plates and sheets are carbon steel pressure vessel plates with superior strength and toughness. Their content consists of Carbon (0.31% max), Manganese (0.79–1.30%), Phosphorus (0.035% max), Sulfur (0.035% max), and Silicon (0.13–0.45%). These plates have superior mechanical properties, including tensile strength of 485–620 MPa, yield strength of not less than 260 MPa, and elongation of 17–21%. Being suitable for moderate to high-temperature service, they possess fine weldability and toughness and are therefore best used in boilers, pressure vessels, and structural uses in severe industries.
