Inconel 625 Bolts and Nuts

 

Metric & Imperial ASTM F468 UNS N06625 Stud Bolts and Threaded Rod/ Bar

While Inconel 625 stud bolts are considered for various heavy duty corrosion resistant application, one application that stands out is the production of super phosphoric acid.

Super Phosphoric Acid or what is shortened as SPA is a liquid with a P2O5 i.e. Phosphorus pentoxide concentration that ranges between 69% - 76%. SPA, like phosphoric acid, is a corrosive compound. Hence its production would require one of the stronger alloys. What better than Inconel 625 fasteners! Since bolts are used in the joining of pieces of equipment used in the production process of SPA, are exposed to the chemicals, Inconel 625 Bolts is often preferred by most manufacturers.

This is because this nickel containing Inconel 625 hex bolt performs admirably especially in the production of the third largest mineral acid commodity, i.e. - Phosphoric acid. During the wet processing of phosphoric acid, the Alloy 625 studs come in contact with certain impurities, which are in the form of sulfates, fluorides and fluosilicates. Being resilient to these compounds, the Alloy 625 forging promotes the smooth processing of phosphoric acid.

Additionally, since phosphoric acid does not degrade the ASTM B446 bolts, most manufacturers prefer using Inconel 625. Moreover, the longevity of the Inconel 625 nuts ensures that these are not replaced time and again thereby proving a cost saving alternative.

A Tensile stress areas are computed using the following formula: As = 0.7854 [D- (0.9743/n)]2
Where:
As = Tensile stress area, in.2,
D = Nominal size (basic major diameter), in., and,
n = number of threads per inch.

Alloy 625 screws Uses
  • Heat shields, furnaces and gas turbine engines.
  • It is an ASME approved material of construction under the Boiler and Pressure Vessel Code
  • Resistant to chloride ions, pitting and crevice corrosion; high corrosion-fatigue strength, high tensile strength make Inconel 625 bolts perfect for marine use.
  • Wide range of temperature and pressure resistance make 625 bolts a key component of chemical processing plants.
  • Nuclear power plants use Inconel 625 bolts for reactor core and control rod bolts.

What is Inconel 625 bolts and nuts temperature range?
The Inconel 625 is a nickel chromium molybdenum columbium alloy that has high yield strength and tensile strength and it is produced in different forms. There are also bolts and nuts manufactured in this material. The Inconel 625 bolts and nuts can operate in the temperature range of cryogenic (-20 degrees) to above 1000 degrees Celsius. It is a huge advantage for these bolts and nuts to be used in applications that need to operate under deviating temperatures from cryogenic to elevated temperatures. The applications include heat exchangers, boiler components and super heater elements. There are different types and shapes of these bolts and nuts that can operate in this temperature range.
