Processing heat treatment of Inconel 601 (Alloy 601/UNS N06601)

Inconel 601 (UNS n06601) nickel base alloy is not a precipitation hardening alloy, so it can not be age hardened by heat treatment. When the temperature reaches 900 ℃ after cold working, the material will soften. If the material needs high temperature strength, the solution heat treatment at 1100 ~ 1200 ℃ is recommended. At this time, the cooling method is water cooling, and air cooling can also be used according to the plate thickness. However, in order to avoid carbide precipitation, it is recommended to cool as soon as possible in the temperature range of 500 ~ 800 ℃.

Processability of Inconel 601 (Alloy 601/UNS N06601)

Inconel 601 (UNS n06601) nickel base alloy is easy to hot work. The heating temperature is 1150 ~ 1200 ℃, and the hot working temperature is 1050 ~ 1200 ℃. The simple processing can be carried out below 850 ℃. Cracking will occur in the temperature range of 650 ~ 850 ℃, please avoid this temperature range for processing. In order to avoid carbide precipitation, it is suggested to increase the cooling rate in the range of 500 ~ 800 ℃. 601 alloy has excellent cold workability and can be processed as SUS 310S and alloy800.  

Heating pipes, containers, baskets and chains used in sulfuric acid pickling plants.

Pipes Weight Tolerance

  • The pipes’ weight tolerance depends on the nominal pipe size, as listed below:
  • Pipe of NPS 4 (DN100, 114.3mm) and smaller may be weighed in convenient lots; pipe in sizes larger than NPS 4 shall be weighed separately.
  • Pipes NPS 12 (DN300, 323.8mm) and under, weight tolerance is: -3.5% / +10%.
  • Pipes over NPS 12 (DN300, 323.8mm),weight tolerance is: -5% / +10%.

Pipes Quantity Tolerance

  • Should be within -10% to +10% tolerance, as a rule of thumb (-3/+3% should be acceptable).

Pipes Length Tolerance

  • Seamless and Welded (no filler metal added): if cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/4 in. (6.35 mm) over that specified.
  • Forged and Bored, Cast, and Cast Cold-Wrought: if definite cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/8 in. (3.2 mm) over that specified.
  • For pipe ordered to random lengths, the lengths and variations shall be agreed upon between the manufacturer and the buyer.
