NAS 255 (UNS N08904 SUS890L) is the ratio of SUS 316L and SUS 317L has better corrosion resistance of austenitic stainless steel. Difficulties with 1.5% copper, such as sulfuric acid and phosphoric acid for reducing the acid in terms of these also have very good corrosion resistance. In addition, welding uses a low-carbon properties.
NAS 255 uses corrosion-resistant stainless steel
Sulfuric acid, nitric acid equipment, sea water heat exchangers, chemical equipment, food equipment.
