NVS AISI 304 Stainless Steel Pressed Flange DIN 2642
NVS AISI 304 Stainless Steel Pressed Flange DIN 2642
NVS AISI 304 stainless steel pressed flange: pressed from sheet, with collar. Size range: ½″–10″ (13 sizes). This collared flange is press-formed from sheet metal; it is noticeably lighter than a slip-on flange of the same size.
AISI 304 (1.4301) is a general-purpose chromium-nickel stainless steel. It is widely used in water, heating and cooling, compressed air, food processing and indoor and outdoor applications.
Applications
- PN10 water, air and process pipelines
- Food and beverage plants
- Pipe connections where light weight is required

Selection and installation notes
- It is rated PN10; for higher-pressure lines, choose a slip-on or weld neck flange.
- The bolt pattern and PN class must match the mating flange; check the bolt circle diameter in the size table.
- Where sea water, salty environments or chloride-containing cleaning chemicals are present, choose grade 316.
- AISI 304 is intended for general use; choose AISI 316 for chloride media, sea water and swimming pool applications.
- Direct contact between stainless steel and galvanized or carbon steel can cause galvanic corrosion; use insulation (washers, unions) between different metals.
