What is a Hastelloy C276 Fastener?
Hastelloy C276 Fasteners are high-performance bolts, nuts, washers, and screws made from Nickel-Molybdenum-Chromium alloy (UNS N10276 / W.Nr. 2.4819). They offer exceptional resistance to oxidizing and reducing acids, wet chlorine, ferric/cupric chlorides, and pitting or crevice corrosion. They are widely used in chemical processing, offshore oil & gas, marine, and pharmaceutical industries in Maharashtra and globally.
What sizes of Hastelloy C276 Fasteners are available in Maharashtra?
Sankalp Alloys Overseas supplies Hastelloy C276 Fasteners in Maharashtra in bolt/nut sizes from M3 to M56 (3/6" to 2") and washer sizes M1 to M64. Custom sizes and non-standard dimensions are also manufactured on request. Same-day dispatch is available from our Mumbai warehouse to anywhere in Maharashtra.
What is the difference between Hastelloy C276 and Hastelloy C22 Fasteners?
Hastelloy C276 has higher Molybdenum content (15–17%) giving it superior resistance to reducing acids and pitting corrosion. It is the most widely used alloy in chemical processing. Hastelloy C22 has better resistance to oxidizing acids and localized corrosion. C22 is preferred in environments where both strong oxidizing and reducing conditions coexist. For most chemical plant applications in Maharashtra, C276 is the industry standard choice.
What standards do Hastelloy C276 Fasteners comply with?
Our Hastelloy C276 Fasteners conform to ASTM B574, ASME SB574, DIN 931/933/934, BS, IS, and JIS standards. Dimensional standards include ASME B18.2.1 and ISO 4014/4032. Material Test Certificates (MTC 3.1 as per EN 10204) with NABL-approved lab reports are provided with every supply.
What temperature range can Hastelloy C276 Fasteners withstand?
Hastelloy C276 Fasteners can withstand temperatures from cryogenic (-196°C) up to 1040°C continuous service temperature. The melting point of the alloy is approximately 1370°C. This makes C276 fasteners ideal for high-temperature industrial applications including heat exchangers, furnace components, and power plant equipment.
