Hindco Steel and Alloys, as Nitronic 50/60 Fasteners Exporters, supplies these top-class, stainless steel fasteners made from nitrogen-strengthened austenitic alloys—Nitronic 50 (XM-19) and Nitronic 60 (UNS S21800). While Nitronic 50 Fasteners are recognized for their great physical properties and overall corrosion resistance, Nitronic 60 Fasteners are designed with the main target to be resistant to galling and wear. Also, these fasteners are produced in accordance with international standards such as ASTM A193, ASTM A194, and ISO 3506 which guarantee their uniformity and quality. In fact, their chemical compositions provide the perfect combination of strength and oxidation resistance even at elevated temperatures.
As a recognized Nitronic 50/60 Fasteners Stockists, Hindco Steel and Alloys is committed to providing products that deliver long-lasting performance benefits to multiple industrial sectors. The strength of such fasteners is two times that of normal stainless steels' yield strengths, which makes them very suitable for high-stress applications. Nitronic 50 exhibits excellent resistance to pitting, crevice corrosion, and chloride stress cracking, while Nitronic 60 offers the best wear resistance that is also compatible with the requirements of the Low-Temperature applications. The fact that these alloys are also strong at cryogenic temperatures is an indicator that maintenance costs will be low and the service life will be extended in this way. Besides, their strength and corrosion resistance will make them a highly cost-effective solution for industries that are looking for sustainable and reliable hard facing under even extreme conditions.
Hindco Steel and Alloys produces and markets a broad spectrum of Nitronic 50/60 Fasteners such as bolts, nuts, washers, studs, screws, and threaded rods. These fasteners, which are available in standard and non-standard sizes and finishing, are designed with the highest precision to meet specific industry requirements. This product range meets the requirements of international standards such as ASTM A276 and A479, which ensure their compatibility and functionality in various industries. Moreover, whatever be your need for marine-grade Nitronic 50 bolts or high-temperature Nitronic 60 nuts, Hindco Steel and Alloys will always have the right answer for every application.
Nitronic 50/60 Fasteners Uses and Applications:
