forging
Inconel 713C 693 Alloy Polished Pipe is actually a cast alloy and is not easily forged, mainly because of the large amount of precipitated elements that must be put into solution before forging. On the one hand high temperatures are required to influence this solution, on the other hand the final forging temperature itself must be quite high. We must not forget the high-temperature strength of this alloy, and even with good high-temperature ductility, the thermal working process can be difficult. This alloy can be forged between approximately 2200/1900 (1205/1040).
heat treatment
Inconel 713C powder is typically used in the as-cast condition, but 1700/1900 (925/1040) stress rupture life can be improved by solution treatment at 2150 (1175) for 2 hours, followed by air cooling. Under these conditions, the material was tested at a stress of 1350 (730) and showed a significant decrease in fracture life and ductility. However, stabilization at 1700 (925) for 16 hours, followed by air cooling, restores the 1350 temperature characteristics and maintains the high temperature characteristics. Precipitation treatment is best carried out between 1470/1650 (800/900).
Machinability
Inconel 713C powder has a very high work hardening rate and is therefore very difficult to process. Of course, the tools have to be sharp and the equipment extremely sturdy. It's best to leave this job to those who are most familiar with it. It has been suggested that final processing should be carried out after precipitation treatment.
Weldability
This grade is not weldable by normal definition, but there has been some success welding 713C to other more easily weldable metals, or making light section match welds at low stresses. Hastelloy W or Inconel 92 filler metal can be used in gas tungsten arc processes.

Inconel 713C 693 alloy Polished Pipe
Inconel 713C alloy is a γ' phase precipitation strengthened nickel-based casting superalloy. Due to its good comprehensive properties, this alloy is currently widely used in various industrial fields, especially aerospace, shipbuilding, automobiles, petrochemicals, etc. This alloy is prone to metallurgical defects during casting production, such as porosity and pores, which seriously affect the reliability of the alloy and the yield of castings.
Inconel 693/UNS N06693 nickel-based superalloy is mainly composed of nickel (Ni) and iron (Fe), with the nickel content being approximately 50% to 60%. In addition, Inconel 693 also contains elements such as chromium (Cr), molybdenum (Mo), aluminum (Al), titanium (Ti), niobium (Nb), and may contain small amounts of carbon (C), copper (Cu), manganese ( Mn) and other impurity elements.
