Operating from the heart of Kinshasa, Yoane Steel stands as a dedicated partner for industries across Congo, specializing in the reliable supply of SA 516 grade 70 steel. We understand that your projects demand materials of proven integrity, which is why we focus on providing this trusted grade of sheets and plates. Our commitment is to support your critical applications with products that meet rigorous standards, ensuring your structures are built on a foundation of quality and safety.
This particular grade is known for its excellent combination of strength and toughness, especially in moderate to lower temperature environments. Its chemical composition, carefully balanced with carbon, manganese, and silicon, is designed for outstanding notch toughness. This results in a plate steel that is not only strong but also highly resistant to brittle fracture, making it a go-to material when reliability under stress is non-negotiable.
