Thabiso Steel, based in Cape Town, South Africa, is your go-to source for top-notch structural steel products, including S355JR+N Sheets and Plates. These steel plates are celebrated for their durability and versatility, meeting international standards and making them perfect for a wide array of industrial uses. Thabiso Steel prides itself on prompt delivery, outstanding customer service, and competitive pricing, catering to sectors like construction, engineering, and manufacturing throughout South Africa. Their S355JR+N offerings are particularly popular for projects that demand consistent performance and robust structural integrity.
S355JR+N is a non-alloy structural steel grade that comes in a normalized condition (the “+N” part), which boosts its toughness and mechanical properties. It has a carbon content of up to 0.24%, 1.6% manganese, and carefully controlled levels of phosphorus and sulfur. This grade boasts a minimum yield strength of 355 MPa and tensile strength that ranges from 470 to 630 MPa. The normalization process enhances its weldability, ductility, and impact resistance, making it a great choice for general structural applications, especially where extra toughness is needed.
