Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissues. Under normal conditions, nitrogen is a colorless, odorless and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -320 °F it has a water-white appearance and must be handled with care due to its low temperature.
Features
- Colorless, odorless, nonflammable inert gas
- Nitrogen is utilized as a purge gas with stainless steel tube welding as well as a controlled addition for shielding gases utilized to GMAW (gas metal arc weld) of austenitic and duplex grades of stainless steel
- Widely used in the chemical and plastics industries
- Nitrogen can enhance plasma cutting, food processing, inerting and heat-treating operations
