Quantity
NF NiMo28 Bolt and Nut is manufactured using the high-performance material N010665, with sizes ranging from 5/16 to 4 inches and lengths from 30 to 1000 mm. It complies with various international standards such as NF, ANSI, and DIN, and is classified as Grade A. With a tensile strength of up to 690 N/mm² and an elongation rate of 40%, it offers exceptional mechanical properties and corrosion resistance, making it particularly suitable for extreme corrosive environments.
The alloy used in NF NiMo28 Bolt and Nut (Hastelloy C-276) is highly regarded in the industrial sector for its outstanding corrosion resistance. Its unique chemical composition and microstructure enable it to perform excellently in both oxidizing and reducing media, resisting the attack of various highly corrosive substances. This makes it especially suitable for high-temperature, high-pressure, and highly corrosive environments.
1. Performance in Oxidizing Media
Oxidizing media are chemical substances capable of accepting electrons, such as nitric acid, chromic acid, and hypochlorites. NF NiMo28 Bolt and Nut exhibits excellent corrosion resistance in oxidizing media, primarily due to its high chromium content (14.5-16.5%). Chromium forms a dense chromium oxide (Cr₂O₃) protective layer on the surface, effectively preventing further corrosion by the media.

2. Performance in Reducing Media
Reducing media are chemical substances capable of donating electrons, such as hydrochloric acid, sulfuric acid, and phosphoric acid. The corrosion resistance of NF NiMo28 Bolt and Nut in reducing media relies mainly on its high molybdenum content (15-17%) and nickel matrix. Molybdenum significantly enhances the alloy's stability in reducing media, especially in environments containing chloride ions.
