SM490 Steel Quality Assurance and International Certification

The production of SM490 steel strictly adheres to JIS G3106 standards, ensuring consistent chemical composition and mechanical properties across every batch. Quality assurance begins with the careful inspection of raw materials and continues through all stages of production, including rolling, heat treatment, and final dimensional and surface checks. This meticulous oversight guarantees that each plate or structural section meets the highest standards for reliability and performance.

Each shipment of SM490 steel is accompanied by a comprehensive Mill Test Certificate (MTC) in accordance with EN 10204 3.1 or 3.2. These certificates detail critical parameters such as yield strength, tensile strength, elongation, and Charpy impact test results. For added assurance, third-party inspections from internationally recognized agencies such as SGS, TUV, or BV can be conducted to validate compliance with technical specifications and project requirements.

Non-destructive testing methods are routinely applied to ensure material integrity. Techniques including ultrasonic testing, magnetic particle inspection, and radiographic evaluation detect internal flaws, surface defects, and potential weld discontinuities before delivery. For critical structural applications such as bridges, high-rise buildings, and offshore platforms, ultrasonic and radiographic testing provide confidence that every plate meets stringent quality and safety criteria.

Leading suppliers like Bebon Steel maintain full traceability for each batch through unique heat numbers. This system allows clients to verify compliance with project specifications at any stage of procurement or construction, ensuring transparency and accountability. Combined with standardized testing and rigorous inspection, this traceability reinforces confidence in the long-term performance of SM490 steel.

Through this comprehensive quality assurance framework and adherence to international standards, SM490 steel has become a trusted choice for global EPC contractors and engineers. Its consistent mechanical performance, verified certification, and reliable fabrication properties make it ideal for demanding structural applications, contributing to the safety, durability, and resilience of critical infrastructure worldwide.
