Characterized by their strength, toughness, and exceptional weldability, these sheets and plates are well-suited for heavy-duty use in construction, engineering, and industrial applications. As Yousef Steel, we hold our products to industry standards to ensure performance and reliability that is second to none. With emphasis on accuracy and client satisfaction, we deliver customized solutions for various project requirements effectively.
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.
