Manufacture Direct Q275/ SS490/ S275JR Hot Forged Alloy Tool Steel Round Bar
1: SS490 steel introduction
SS490 steel has good strength properties that make it suitable for structural applications. It provides sufficient tensile and yield strength to withstand heavy loads and structural stresses, ensuring long-term durability.SS490 has good weldability and is easy to fabricate and assemble. It can be easily welded using common welding techniques such as arc, resistance and gas-melting arc welding (GMAW). This feature contributes to efficient manufacturing processes and the ability to create complex structures.SS490 has good machinability, which means it can be easily machined and formed into a variety of shapes and sizes. It can perform cutting, drilling, and molding operations without excessive tool wear or difficulty, enhancing its usability in the manufacturing process.
