Yoane Steel stands out as a top-notch manufacturer and supplier located in Kinshasa, Congo, with a focus on crafting and distributing high-quality Sailma 350 HI Sheets and Plates. These plates are celebrated for their exceptional strength, durability, and weldability, making them perfect for tackling extreme conditions in structural and engineering projects. Yoane Steel is committed to ensuring that every product meets international quality standards, thanks to their thorough testing and advanced manufacturing techniques. With a strong emphasis on customer satisfaction, prompt delivery, and top-tier materials, Yoane Steel has built a solid reputation across various industrial sectors in Congo and beyond.
Sailma 350 HI plates and sheets are high-strength, low-alloy steel that has superior toughness along with weldability. Their chemical composition includes Carbon (≤0.20%), Manganese (≤1.60%), Silicon (≤0.45%), Phosphorus (≤0.040%), and Sulfur (≤0.040%), which gives superior strength and impact resistance. Mechanically, they provide a minimum yield strength of 350 MPa and tensile strength from 490-610 MPa, with superior elongation as well as toughness even at sub-zero temperatures. These characteristics render them suitable for heavy-duty use in construction, pressure vessels, and structural engineering, with long-lasting performance and reliability.
