Hastelloy C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally considered a versatile corrosion-resistant alloy. C-276 is an improved wrought version of alloy C in that it usually doesn’t need to be solution heat-treated after welding and has vastly improved fabricability. Hastelloy C-276 contained slightly more chromium and molybdenum than alloy C.
Hastelloy C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is extremely versatile material that has found usage in a wide variety of severe environments. It has shown a corrosion resistance to chloride containing media, organic acids, oxidizing media, reducing acids, seawater and brine, and sulfuric flue gasses. The price of this alloy is higher compared to austenitic stainless due to the higher nickel, molybdenum and tungsten content. By far, it is the most popular super alloy.
The Hastelloy C-276 hex bolts and spring-lock washers belong to the range which is combined of molybdenum, nickel and chromium, and thus, it is considered as the most versatile corrosion resistant alloy. The products which we provide conform to all of the industrial, international and commercial standards which make them highly credible to use.
