#Difference between C-276 & Inconel 625

Hastelloy is a trademark for a series of high-strength, nickel based, corrosion resistant alloys produced by Haynes International.

Inconel is a registered trademark of Special Metals Corporation, Inconel is a material that is specifically optimized for some of the toughest use conditions to be found in manufacturing while Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength.

 

#Application on Screws

Both C-276 & Inconel 625 both service in high-corrosive situation, and used a lot also in plastic injection or extrusion field, like acid and HFFR processing, and with remarkable performance.
