Super Austenitic Stainless Steels (NAS 354N, NAS 254N, NAS 185N) |
| Feature |
- As high chromium, high molybdenum, nitrogen-bearing stainless steels,
these products provide high corrosion resistance and crevice corrosion
resistance in environments with high chloride concentrations.
- Corrosion resistance is one step higher than that of conventional SUS304
and SUS316L. Corrosion resistance and crevice corrosion resistance approach
the performance of titanium and nickel-based superalloys.
|
| Application |
- Flue gas desulfurization systems in coal-fired thermal power plants,
salt and paper production plants, seawater heat exchangers, salt production
equipment, flue gas desulfurization equipment, resin production equipment,
chemical reactors, roofing |
|

Super Duplex Stainless Steels (NAS 74N, NAS 75N) |
| Feature |
- Dual-phase structure of austenite and ferrite. Offer a combination of
high corrosion resistance and high strength.
- High chromium, high molybdenum, nitrogen-bearing stainless steels. In
comparison with SUS329J3L and SUS329J4L, provide high local corrosion resistance
in environments with high chloride concentrations.
- Have higher corrosion resistance than SUS329J3L and SUS329J4L.
|
| Application |
- Seawater desalination plants, seawater pumps, flue gas desulfurization
equipment, chemical plants
|

Sulfur Acid Resistant Stainless Steels ( NAS 335X, NAS 155N, NAS 255) |
| Feature |
- As molybdenum- and copper-added stainless steels, these products provide
high corrosion resistance in high temperature, high concentration sulfuric
acid environments and high sulfuric acid dew point corrosion resistance.
- Also possesses high grain boundary corrosion resistance and stress corrosion
cracking resistance.
|
| Application |
Sulfuric
acid production equipment and other equipment routinely exposed to sulfuric
acid (heat exchangers, chimneys, gypsum production equipment, pollution control
equipment) |
|
|
|
| 4 |
Nonmagnetic Stainless Steels ( NAS NM15M, NAS M17) |
| Feature |
-Possess higher strength than conventional nonmagnetic austenitic stainless
steels, and do not display magnetism even when subjected to heavy cold
working. |
| Application |
Nonmagnetic
springs and gaskets, cellular telephones, electronic parts, etc |
|
|
|
| 5 |
NAS Polka Plates |
| Feature |
- An outstanding steel plate for flooring applications.
While
providing an anti-slip effect equal to that of conventional checkered plates,
- NAS Polka Plates place a lower load on the feet while walking, and are
also easy to clean and excellent water repellent. Also, it provides excellent
design characteristics.
|
| Application |
Floors
in food and chemical plants, pit covers, bus steps |
