Workability
Work similar to that with ordinary austenitic stainless steels is
possible.
Weldability
Weldability is on the same level as ordinary austenitic stainless
steels. Preheating and post-heating are not necessary. As welding
electrodes, in applications under severe corrosion environments,
use of welding consumables with equal or higher corrosion
resistance is recommended. When the corrosion environment is not
severe, and when the purpose of welding is for joining, matching
welding consumables may be used.
Heat Treatment
Because NAS 255 is an austenitic stainless steel, heat treatment
also conforms to that of standard austenitic stainless steels. The
solution heat treatment conditions recommended in JIS G4305 are as
follows:
Heat treatment condition: 1030~1180℃; Water cooling
Pickling
A mixture of nitric acid and hydrofluoric acid is used in pickling.
However, due to the high corrosion resistance of NAS 255, 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
Sulfuric acid and phosphoric acid plants, seawater heat exchangers,
chemical plants, food plants, etc.
