A low-alloy, high-strength structural steel called SUPRALSIM 690 was created to offer improved weldability, strength, and toughness. It has a high resistance to wear, impact, and fatigue because it is made of carbon, manganese, silicon, nickel, chromium, and molybdenum. The material offers outstanding low-temperature toughness, long fatigue life, and superior tensile strength, with a minimum yield strength of 690 MPa. SUPRALSIM 690 is a flexible option for demanding structural and engineering applications because it is well-suited for settings that require high mechanical performance and is renowned for its exceptional weldability and formability.
SUPRALSIM 690 plates and sheets are designed for uses where outstanding structural performance, strength, and durability are essential. These low-alloy, high-strength steel plates perform exceptionally well even at low temperatures and are made to withstand harsh working environments. They are perfect for projects needing dependable mechanical resistance, impact tolerance, and simple fabrication because of their balanced chemical composition and thermomechanical qualities. SUPRALSIM 690 is used extensively in industries where both static and dynamic stress are prevalent due to its high toughness and exceptional weldability, which provide reliable performance under heavy loads, extreme pressure, and mechanical fatigue over extended service periods.
