Phanuphong Steel has built a solid reputation as a reliable manufacturer and supplier of S355MC Steel Sheets and Plates right in the heart of Bangkok, Thailand. They’re all about delivering top-notch structural steel solutions that cater to a variety of industries. S355MC is a high-strength low-alloy (HSLA) steel grade that falls under EN 10149-2, crafted to offer enhanced formability, weldability, and toughness. Its impressive strength-to-weight ratio makes it a go-to choice for applications where reducing weight without sacrificing strength is key. Phanuphong Steel prides itself on maintaining strict quality control, offering competitive prices, and ensuring timely deliveries, serving sectors like construction, automotive, heavy machinery, transportation, and energy with durable and dependable steel products.
The S355MC Steel Sheets and Plates are made from a carefully balanced mix of elements, including carbon, manganese, phosphorus, sulfur, and silicon, along with micro-alloying additions of niobium, vanadium, or titanium to boost strength and toughness. These plates deliver a minimum yield strength of 355 MPa, tensile strength between 430–550 MPa, and impressive elongation values for great formability. The controlled chemical composition guarantees a fine-grain structure, excellent weldability, and resistance to brittle fracture. Thanks to their outstanding mechanical properties, S355MC sheets and plates are perfect for forming, bending, and welding in demanding structural applications that require both strength and durability.
