Nial Sheets and Plates is a prominent manufacturer and supplier based in Houston, USA, specializing in high-quality stainless steel products. The company offers an extensive range of stainless steel foils, including Stainless Steel 321 Foils, known for their exceptional resistance to corrosion and excellent performance in high-temperature environments. Stainless Steel 321 is stabilized with titanium, making it highly resistant to intergranular corrosion and ideal for applications involving welding and heat exposure. Nial Sheets and Plates provides precision-engineered, durable foils that meet the needs of diverse industries, offering reliable solutions for demanding applications worldwide.
UNS S32100 Foils primarily consist of iron, with key alloying elements including 17-19% chromium (Cr) and 9-12% nickel (Ni). It also contains up to 0.8% titanium (Ti), which stabilizes the material against sensitization and intergranular corrosion. Other trace elements such as manganese (Mn), silicon (Si), carbon (C), sulfur (S), and phosphorus (P) are present in small amounts. The mechanical properties of 321 Foils include a tensile strength of approximately 520-720 MPa, yield strength of 205 MPa, and an elongation of 40-50%. It also exhibits excellent weldability and resistance to high temperatures.
