Guided by dedication to quality, innovation, and customer satisfaction, Yunus Sheets and Plates provides products that are up to international standards and rigorous industrial expectations. Our S420 plates and sheets are produced on high-end machinery and rigorously followed quality control measures to have higher strength, weldability, and formability. Being a domestic as well as international market player, we supply customized construction, engineering, and heavy machinery industry solutions, thus being a go-to supplier for high-strength structural steel plates.
S420 sheets and plates are structural steels with a minimum yield strength of 420 MPa. The general chemical composition consists of carbon (max 0.20%), manganese (up to 1.70%), phosphorus (max 0.025%), sulfur (max 0.015%), and silicon (up to 0.50%). These plates exhibit good toughness and impact strength, particularly at sub-zero temperatures. The tensile strength is between 520 to 680 MPa with elongation values of 18–20%. The material is suited for applications that demand a good strength-to-weight ratio, good weldability, and reliable performance under dynamic or heavy loads in many different engineering environments.
