HARDO X450 properties equivalent indian standard

    
    
    
    Indian Standard 750 (IS-750) is a set of standards and guidelines meant for the construction and design of steel girder bridges in India. These standards are based on the principles of maintaining structural integrity, increasing durability, and providing long-term dependability. The main focus of this standard is to ensure the highest degree of safety and reliability throughout the entire life-span of a bridge. IS-750 provides detailed guidance on various aspects including bridge construction, civil engineering principles and standards, steel fabrication and welding, as well as various design features.
    
    HARDO X450 is a commercial grade steel, commonly used for fabricating bridges, buildings, and other structural components. It is a low-alloy steel, with enhanced mechanical performance and improved corrosion resistance compared to similar alloys. The main components of HARDO X450 are carbon, manganese, silicon and molybdenum, with trace elements of iron, phosphorous, and sulfur. The low-alloy steel is designed to optimally balance ductility, weldability, and strength, with agility and enhanced wear resistance.
    
    The two materials share several properties and adhere to the same standards. In comparison, HARDO X450 has an increased mechanical performance and improved corrosion resistance, providing an overall better resistance and durability than IS-750. In bridge applications, HARDO X450 offers a reliable and economical solution while maintaining structural integrity through its decreased inter-granular fracture and sharp decline in hydrogen-related cracking.
