Alloy 330 uns n08330 is an austenitic nickel, Iron, Chromium alloy developed to provide remarkable resilience to carburizing and oxidizing atmospheres at elevated temperatures. With a nickel content of 34 to 37 percent, The alloy remains exceptionally durable against both chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase. It is readily fabricated using standard procedures for constructed made with durable stainless steel material and nickel alloys. The alloy is widely utilized in elevated temperatures where resistance to the combined effects of thermal cycling and carburization is required. The high nickel and chromium content Offers superior resistance to both oxidation and carburization. The oxidation resistance is also enhanced by the silicon content of the alloy. The alloy performs well under cyclic conditions of temperature regulation and in alternate carburizing and oxidizing atmospheres. Alloy 330 offers an elevated standard of exceptional durability against corrosion, Mainly to oxidation, Carburization, And nitridation. It is readily fabricated using standard procedures for stainless steels and nickel alloys. The alloy is used extensively in elevated temperature atmospheres where resistance to the combined effects of thermal cycling and carburization is required.
