SB 423 UNS 8825 refers to ASTM/ASME SB-423, the standard specification for seamless pipes and tubes made from Incoloy Alloy 825 (UNS N08825), a high-performance nickel-iron-chromium alloy known for its exceptional resistance to various corrosive environments, including sulfuric, phosphoric, and nitric acids, making it ideal for chemical processing, oil & gas, and pollution control equipment.
SB 423 UNS 8825 pipes are premium stainless steel pipes (Incoloy 825) built tough for extreme corrosion, often used in heavy-duty industrial settings where regular steel would fail.
