ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering ASTM B574 UNS N10276 round bar at factory-direct prices with full material traceability and fast global delivery. ASTM B574 specification covers rod and bar of low-carbon nickel-chromium-molybdenum alloys, including UNS N10276 (Hastelloy C-276), for use in general corrosive service . Nickel alloy C276 is a nickel-molybdenum-chromium-tungsten alloy with good fabricability and impressive corrosion resistance in some of the most severe environments. Due to its properties, C276 is commonly used in pollution control, chemical, petrochemical, and waste incineration applications .
Specifications & Physical Data Alloy C276 is a solid-solution strengthened nickel-chromium-molybdenum alloy with tungsten addition. The low carbon content (0.010% max) significantly reduces carbide precipitation during welding, maintaining resistance to intergranular attack in the heat-affected zone . The alloy is supplied in the solution annealed condition for optimal corrosion resistance. Available Forms: Round bar, flat bar, sheet, plate, strip, tube, weld wire, weld rod, forging stock, pipe Specifications: ASTM B574, ASME SB574, UNS N10276, Werkstoff Nr. 2.4819, NACE MR0175/ISO 15156
