The Definition Of Hastelloy C-276

Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent corrosion resistance and good forging properties. It is suitable for the corrosion of inorganic acid, organic / inorganic chlorine contaminated media, formic acid, acetic acid, acetic anhydride, seawater, and saline solution Environment, able to withstand pitting corrosion, crevice corrosion, stress corrosion cracking. C-276 is considered to be the most versatile corrosion-resistant material.

Mechanical behavior

Tensile properties at room temperature-test sample solution treatment + water quenching

Heat treatment


Heat to 1121-1149 ° C for 1 hour / inch thickness, then water quench
Stress relief heat treatment is not very effective, should be fully annealed heat treatment
C-276 can not increase the hardness through heat treatment, but can only be hardened by cold work.
Processing performance
What Is Hastelloy C-276
Thermal processing
The forging temperature is 1204 ° C. Annealing after forging can get the best corrosion resistance.
Machine Plus
C-276 can be processed by conventional methods. It is recommended to use tungsten carbide tools
C-276 can use tungsten gas shielded welding, metal electrode gas shielded welding, arc welding and resistance welding. Using a minimum amount of continuous heating and ensuring sufficient penetration can reduce thermal cracking. Do not use oxyacetylene welding to avoid carbonization.
Most chemical and petrochemical processing equipment can use C-276 welding status.
