Nitronic 40

Nitronic 40 Industries & Applications

Since Nitronic 40 has a high corrosion resistance, machinability and weldability, this makes it a versatile steel that can be used in a variety of industries and applications, but is most commonly used in the aerospace industry. Other industries and applications include:

• Aerospace and airplane technology
• Manufacturing
• Medical & hospital industries
• Natural gas facilities
• Clamps
• Flanges
• Hydraulic tubing
• Chemical processing
• Pollution control equipment
• Cryogenic applications
• Steam and autoclave parts

Features of Nitronic 40

Corrosion Resistance – It has a high corrosion resistance. Specifically, in chemical applications, it is similar to that of Type 304 stainless steel. It has shown excellent cracking resistance in tests for 15 years at ambient temperatures in severe seacoast atmospheres. This makes it an excellent candidate for withstanding everyday wear and tear. Nitronic 40 is an excellent choice for multiple high heat, heavy duty applications.

Machine/Weldable – The work hardens during machining. This requires rigid tooling, heavy feeds, and slower speeds. It is also readily weldable using TIG, MIG and shielded metal arc welding methods. Like other Nitronic grades, the high nitrogen content can interfere with electron beam welding by severe outgassing.

Workable – One can use it in various temperatures and annealing gives the best stress rupture life for operating temperatures between 1300 to 1600 degrees. Heating for hot working should be in the temperature range of 2100˚F to 2200˚F.

Fabricate – The In-process annealing may be done between 1950˚F to 2050˚F.
