Thanks to their consistent quality, prompt delivery, and cost-effective solutions, Wiraphan has become a go-to partner for clients both locally and globally.
Stainless Steel 348 Sheets and Plates are a type of austenitic stainless steel, primarily made up of iron, 18–20% chromium, 8–12% nickel, and stabilized with niobium to prevent carbide precipitation. This unique composition offers remarkable resistance to intergranular corrosion, oxidation, and scaling at elevated temperatures. On the mechanical side, these sheets and plates provide high tensile strength, toughness, and thermal stability, along with good ductility and weldability. The niobium stabilization enhances durability during welding and ensures long-term performance in high-temperature settings, making 348 Sheets and Plates ideal for fabrication, forming, and structural applications in challenging industrial environments.
