Workability  incoloy 25-6mo

Cold and hot workability are approximately equal to those of Type 304, 316, and other standard austenitic stainless steels. However, care is necessary for both cold and hot worked materials because they have high strength.

Weldability  incoloy 25-6mo

Possible welding methods include shielded metal arc welding, TIG welding, and plasma welding, in the same manner as with standard austenitic stainless steels. As welding consumables, Alloy 276 should be used. Preheating and post-welding heat treatment are not necessary.

Machinability  incoloy 25-6mo

As a distinctive feature of high Ni stainless steels, machinability is difficult in comparison with the austenitic stainless steels, but is easier than with Ni-based alloys. Use of a superhard tool whenever possible, together with a slow feed speed and large cut depth, is advised.

Heat Treatment  incoloy 25-6mo

Because N08926 is an austenitic stainless steel, heat treatment also conforms to that of standard austenitic stainless steels. The heat treatment conditions normally used with this material are as follows:

• Solution heat treatment: 1125~1175℃; Water cooling

Pickling  incoloy 25-6mo

A mixture of nitric acid and hydrofluoric acid is used in pickling. However, due to the high corrosion resistance of N08926, scale is somewhat difficult to remove in comparison with Type 304. Therefore, the material should be immersed in an alkaline solution before pickling, or if possible, shot blasting is extremely effective.

Applications  incoloy 25-6mo

• Seawater environments: Seawater desalination equipment, heat exchangers using seawater, condenser tubes, etc.
• High concentration chlorine ion environments: Flue gas desulfurization systems, pulp and papermaking industries, various types of bleaching equipment, etc.
• High concentration salt-containing environments: Resin manufacturing equipment, chemical reactors and piping, etc.
