Fastener Materials

Inconel, Hastelloy, and Nimonic alloys are engineered to maintain strength and resist oxidation at elevated temperatures exceeding 1000°F (538°C). These nickel-based superalloys are widely used in power generation, petrochemical, and aerospace fastener applications.

Super Duplex stainless steel and Hastelloy provide exceptional corrosion resistance in aggressive chemical and marine environments. For seawater applications, Copper Nickel and Aluminium Bronze are also excellent choices due to their resistance to biofouling and dezincification.

Duplex stainless steel (e.g., 2205) offers roughly twice the strength of standard austenitic grades with good corrosion resistance. Super Duplex (e.g., 2507) provides even higher strength and superior resistance to pitting and crevice corrosion, making it ideal for offshore oil and gas applications.

All Ananka fastener materials comply with international standards including ASTM A193/A194, ASME, DIN, ISO 9001:2015, and ASME B18.2.1. Each product comes with full material traceability and Mill Test Certificates as per EN 10204/3.1B.

Yes, Ananka Fasteners manufactures custom fasteners in all 19+ material grades listed on this page, including exotic alloys like Nimonic, Nitronic, SMO 254, and Phosphor Bronze. Contact our sales team with your specifications for a custom quote.

Material selection depends on operating temperature, corrosive environment, mechanical load, and industry-specific standards. Stainless steel works for general-purpose use, nickel alloys for extreme heat, and copper alloys for marine environments. Our engineering team can recommend the optimal grade for your specific requirements.
