Main Performance Characteristics of Hastelloy C276 Pipe
hastelloy c276 pipe Corrosion Resistance
Hastelloy C276 Pipe shows excellent corrosion resistance to strong acids such as hydrochloric acid, sulfuric acid, acetic acid, formic acid, and phosphoric acid, as well as chlorine-containing media (such as seawater, chloride solutions, and chlorine gas). It performs particularly well in reducing corrosive environments and can withstand sulfuric acid with a concentration of ≤90% (at room temperature) and hydrochloric acid with a concentration of ≤30% (at room temperature).
alloy n10276 High-Temperature Mechanical Properties
UNS N10276 pipe maintains stable mechanical properties in the temperature range of -253℃ to 1093℃. At room temperature, the tensile strength is ≥690MPa, the yield strength is ≥310MPa, and the elongation is ≥40%. It can be used in pressurized pipelines under high-temperature conditions.
hastelloy n10276 tube Processing Performance
It can be welded (using matching welding wire ERNiCrMo-4), bent, and cut. However, after welding, prolonged exposure to temperatures between 650℃ and 1040℃ should be avoided to prevent precipitation of phases that could lead to performance degradation, after cold working, plasticity can be restored through solution treatment (holding at 1120℃-1150℃ followed by rapid cooling).
alloy c276 pipe Wear Resistance
In conditions where corrosion and wear coexist (such as the transportation of corrosive fluids containing particles), its wear resistance is superior to ordinary stainless steel pipes (such as 316L).
