Properties of Hastelloy C276 Alloy
Hastelloy C276 Cold Forming
Annealed treatment is followed for every forming operations. For cold deformation at high-level, cold forming is done for the deformation process where cracking is a possibility because of mild forming. The cold forming process is used to restore the resistance to stress corrosion cracking. For most of the time, a solution anneal is recommended after the complete formed or annealed operation which helps to restore the material to its optimum condition and properties.
Hastelloy C276 Hot Forming
Hastelloy C276 can be hot-worked into various forms but they are more sensitive to the amounts and rates of hot-reduction with the austenitic stainless steels. During Hot working, all parameters should be taken into account. Special attention should be given to the temperature at which the alloy begins to melt. The high strengths of the Hastelloys at elevated temperature, their low thermal conductivity, and their hardening rate. Moreover, when the temperature is low in the hot working range of the metal, they are resistance to deformation is increased rapidly. So, while hot working practices that give heavy initial reduction followed by moderate final reductions, also with frequent re-heating gives the good result.
Hastelloy C276 Machining
Hastelloy C276 can be machined using conventional production methods at satisfactory rates. During the machining processes these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. Following are key points that should be considered during machining operations: Capacity, Tooling, Lubrication/Coolants, Drilling. The actual operating parameters are to serve only as a guide and are not to be taken as absolute values.
Hastelloy C276 Welding
Gas tungsten-arc welding, gas metal-arc welding, shielded metal-arc (coated electrode) welding, or resistance welding may be used. Minimum heat input consistent with adequate penetration reduces the chance of hot-cracking. Oxyacetylene welding should be avoided due to possibility of carburization. Hastelloy C-276 can be used in the as-welded condition in most chemical and petrochemical process equipment
Hastelloy C276 Heat Treatment
Wrought forms of Hastelloy C-276 are furnished in the solution heat-treated condition unless otherwise specified. Alloy C-276 is normally solution heat-treated at 2050 °F and rapid quenched. Parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation, if possible
