Hastelloy C4 Fasteners are made from a versatile nickel, chromium, and molybdenum superalloy. It is part of the Hastelloy C-series, which has high resistance to heat-affected zone sensitizations. This alloy is one of the most stable alloys of the Hastelloy alloy family. It is well known for its resistance to harsh and corrosive chemicals such as hydrochloric acid, sulfuric acid, and chlorides. Because of the stability in its microstructure, Hastelloy C4 Socket Set Fasteners can be welded without the worry of sensitization. This means that it doesn't allow the formation of grain boundaries precipitates on the as-welded heat-affected zone.

Hastelloy C4 Fasteners feature exceptional high-temperature stability, great ductility and corrosion resistance. It can be serviced within the range of 649°C to 1038°C. The alloy has great stress corrosion cracking and oxidizing resistance up to the temperature of 1038°C. Forming and welding can be done easily on this nickel alloy with good creep resistance.

Because of its high chromium and molybdenum concentration, it can resist both oxidising and non-oxidising acids. The melting point of Hastelloy C4 is around 1399°C and has a tensile strength of 107 Ksi (min) and yield strength of 71.4 Ksi (min). The heat treatment method can be solution annealed and should be proceeded immediately with rapid quenching with water. After annealing, the alloy's tensile strength increases.

Hastelloy C4 Concrete fasteners resist the deposition of grain boundary precipitates on heat-affected welded areas and have good creep resistance. It has many uses in chemical process applications in an as-welded state and nuclear fuel processing.

Zeon Fasteners LLP uses the best raw inputs to create high-quality C4 hastelloy fasteners. These fasteners are available in various sizes and kinds, and they may be modified to meet the client's demands. Our organisation's main mission is to provide value to our customers and maximize customer satisfaction.
