With a strong emphasis on durability, reliability, and precision, this company delivers materials that adhere to international standards for construction, engineering, and fabrication projects. Renowned for their exceptional strength and weldability, S355JO+N steel sheets and plates are a popular choice for structural applications. Phanuphong Steel guarantees consistent quality, timely deliveries, and competitive pricing, making them a trusted partner for clients across different sectors in need of high-grade steel solutions.
S355JO+N steel sheets and plates are alloy structural steels that include elements like carbon, manganese, silicon, and controlled trace impurities such as phosphorus and sulfur. This specific composition boosts their toughness and weldability. On the mechanical side, they showcase impressive yield strength around 355 MPa, tensile strength ranging from 470 to 630 MPa, and solid impact resistance at 0°C, ensuring they hold up well under tough conditions. Thanks to the normalized rolling (N) process, the steel achieves uniform mechanical properties, dimensional stability, and resistance to brittle fractures, making it perfect for structural and fabrication uses.
