When you need a material that can handle extreme heat and stress without breaking a sweat, UNS N07041 alloy steel plate, also known as Rene 41, is the go-to choice.
Supplied by Gangsteel, a trusted stainless steel supplier in China, this nickel-based superalloy shines in high-temperature environments up to 982°C (1800°F), offering unmatched strength, creep resistance, and UNS N07041 oxidation resistance. It’s a top pick for aerospace components and gas turbine parts.
Gangsteel provides UNS N07041 plate, sheet, bar, and custom components, all meeting ASTM B637 and ASME SB-637 standards. Here, you’ll find everything you need to know about UNS N07041 chemical composition, mechanical properties, equivalent materials, specifications, applications, and the UNS N07041 price per kg. Check out our nickel alloy steel grades for related alloys like UNS N06625, UNS N07718, and UNS N07263.
UNS N07041, or Rene 41, is a nickel-based superalloy with about 55% nickel, 19% chromium, and significant additions of cobalt, molybdenum, titanium, and aluminum for precipitation hardening. This gives it exceptional strength and creep resistance at high temperatures, making UNS N07041 material perfect for jet engine components, turbine blades, and high-stress aerospace parts. Compared to UNS N07263, UNS N07041 handles higher temperatures but is less weldable, requiring careful processing.
Gangsteel’s UNS N07041 alloy steel plate is engineered for extreme conditions, offering a premium option among nickel alloy steel grades like UNS N07080 and UNS N09901.
