Nial Sheets and Plates, a top-notch manufacturer and supplier based in Houston, USA, specializes in high-quality stainless steel products, including their Stainless Steel 348 Angles. These angles are crafted to withstand high temperatures and corrosive environments, offering a fantastic blend of strength and exceptional resistance to intergranular corrosion. Nial’s 348 angles are meticulously fabricated to cater to the demands of critical sectors like aerospace, chemical processing, and power generation. With a strong focus on quality, compliance, and timely delivery, Nial is dedicated to supporting industrial clients who need durable, high-performance stainless steel structural components that can handle tough conditions and ensure long-lasting reliability.
When it comes to composition and mechanical properties, Stainless Steel 348 is a niobium-stabilized austenitic stainless steel, sharing a chemical makeup similar to 304. It typically contains around 17–20% chromium, 8–11% nickel, along with some columbium (niobium) and tantalum. These stabilizers enhance its resistance to carbide precipitation during welding and exposure to high temperatures. With a tensile strength of about 75,000 psi and a yield strength close to 30,000 psi, it boasts excellent toughness and elongation. It can maintain its mechanical integrity in environments reaching up to 1600°F (870°C), making it perfect for heat-treated and welded structures that face thermal cycling and corrosive agents.
