Hastelloy C276 is one of the highly demanded and versatile alloys that shows some good mechanical properties. The Hastelloy c276 fasteners show good corrosion resistance in moderately oxidizing and highly reducing environments. They are also resistant to stress corrosion cracking and localized attacks. As Hastelloy alloy c276 washers can resist most of the severe chemicals, hence they can be used in sour gas service, power plant, chemical processing and other critical applications.
The WNR 2.4819 socket head cap screw material has molybdenum and chromium in its alloy, with added tungsten. This makes the material highly resistant to chloride related stress corrosion cracking, pitting, along with crevice and general corrosion. They can operate in an oxidizing atmosphere up to 1038 °C.
However, due to low chromium content, they cannot successfully resist highly oxidizing environments which include hot and concentrated nitric acid. The nickel c276 threaded rod has a low carbon content and hence can be utilized in as-welded conditions. They cannot be hardened by heat treatment but by cold working. They have a higher work hardening rate than the standard austenitic stainless steel grades.
Hastelloy c276 bolts can be used in sea water applications as they possess excellent corrosion resistance properties. It can also resist pitting, crevice corrosion and stress corrosion cracking in harsh conditions that occurs in marine environment. The high nickel content, along with molybdenum and chromium enhances the rust resistance properties. The alloy c276 bolts also have high strength and they come with a long service life.
