Russ Fasteners provides premium Hastelloy Fasteners in Singapore, Pulau Ujong, for applications requiring severe corrosion resistance and mechanical strength. Such fasteners, such as bolts, nuts, washers, screws, and studs, are fabricated from nickel-based alloys like Hastelloy C-22 and C-276. Designed for chemical, marine, and high-temperature applications, Hastelloy Fasteners are renowned for outstanding performance in austere environments. Russ Fasteners produces these parts to exacting specifications, guaranteeing dimensional stability, consistent fastening, and long-term strength. Offering resistance to aggressive acids, oxidizers, and high-pressure steam, Hastelloy Fasteners are critical components for mission-critical equipment and infrastructure.
Hastelloy Fasteners consist of chromium, molybdenum, and iron-containing high-nickel alloys. Grades such as C-276 and C-22 have tensile strengths ranging from 690–800 MPa and possess excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. They maintain mechanical strength in both oxidizing and reducing environments, even at high temperatures of up to 1040°C. They are weldable, ductile, and highly resistant to fatigue and thus are well used in chemical plants, offshore platforms, and high-pressure systems. Their formulation provides enhanced performance in conditions that are too severe for stainless steel or inferior alloys.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Hastelloy Fasteners are utilized where other metals break down—chemical processing, pollution abatement, marine facilities, power generation, and pharmaceutical production. They protect equipment like reactors, vessels, heat exchangers, pumps, and flanges against aggressive media including sulfuric acid, hydrochloric acid, chlorine, and seawater. They withstand pitting and crevice corrosion in offshore platforms and desalination units. In the drug industry, they avoid contamination and endure harsh cleaning cycles. Hastelloy Fasteners offer unparalleled performance where absolute reliability, corrosion resistance, and structural integrity under severe thermal, chemical, and mechanical stress are required.
The Hastelloy fasteners that are manufactured at Russ Fasteners are packed with a lot of precaution. Every fastener is packed in individual protective material to avoid any damage, rusting or contamination during transportation.
