SSF’s substantial experience in working with high nickel alloys bolting is crucial as they are extremely difficult materials to machine and can require various forms of additional treatment to ensure full conformity. Related by their high percentage of nickel in their composition, these highly corrosion-resistant materials are widely used in the petrochemical and offshore sector, and are often better known by their registered trade names (e.g. Inconel®, Hastelloy®, Monel® and Nimonic®).

Inconel® bolting

We produce inconel fasteners in several grades. Inconels are austenitic nickel-chromium superalloys. They are used in extreme environments, often in gas turbines, nuclear reactors and natural gas processing plants.

Hastelloy® bolting

Hastelloy bolts & nuts can be most effective under high temperatures and corrosive environments, with high stress resistance.

Monel® bolting

SSF manufactures Monel fasteners in A400 and K500. Monel grades are nickel-copper based alloys and have high corrosion resistance and strength properties. They are often used in valves, pumps and heat exchangers.

Incoloy® bolting

SSF produces various grades of Incoloy bolts & nuts. Another of the superalloys, it is used in extreme environments.

Nitronic Bolting

Nitronic grade fasteners have excellent corrosion resistance properties and strength. It has low magnetic permeability and excellent cryogenic properties.

Duplex
Super Duplex
Titanium
Stainless Steel and others
