904L,UNS N08904, SUS 890L - High Corrosion Resistant Stainless Steel steel pipe tee fittings
UNS N08904, SUS 890L is an austenitic stainless steel with superior corrosion resistance in comparison with Type 316L and Type 317L. Due to addition of Cu (1.5%), this material displays excellent corrosion resistance against reducing acids such as sulfuric acid and phosphoric acid. It is used in chemical plants and a wide range of other applications. Shanghai Bozhong Steel Group supplies this product in plate, sheet and strip form.

Dimensions of Straight Tees and Crosses

GENERAL NOTE: All dimensions are in millimeters.
NOTES:
(1)Outlet dimension M for NPS 26 and larger is recommended but not required.
(2)Dimensions applicable to crosses NPS 24 and smaller.

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.
