UNS N07214 alloy steel plate, known as Haynes 214, is a nickel-chromium-aluminum-iron superalloy supplied by Gangsteel. Designed for unmatched high-temperature oxidation resistance above 1750°F (955°C), UNS N07214 material excels in aerospace, gas turbines, and industrial furnaces.
As a leading stainless steel supplier in China, Gangsteel offers UNS N07214 plate, sheet, strip, and custom components, meeting AMS 5542, ASTM B435, and ASME SB-435 standards. This page details the UNS N07214 chemical composition, mechanical properties, equivalent materials, specifications, and applications, with competitive UNS N07214 price per kg. Explore our nickel alloy steel gradesfor related alloys like UNS N06002and Alloy C276.
UNS N07214, or Haynes 214, is a nickel-based superalloy with high aluminum (4.0-5.0%) and yttrium (0.002-0.040%) content, forming a protective Al₂O₃scale for superior oxidation resistance above 1750°F (955°C). Its excellent formability and weldability make UNS N07214 alloy steel plate ideal for high-temperature environments like jet engine combustors and furnace components. Compared to UNS R30188, UNS N07214 offers better oxidation resistance but lower sulfate corrosion resistance.
