In-Depth Guide to Hastelloy Fastener Grades

Choosing the right Hastelloy alloy is critical. Below is a detailed breakdown of key grades, including their composition, properties, and ideal applications.

1. Hastelloy C276 Bolts & Hastelloy C Bolts

• Chemical Composition (Typical): Nickel (Ni) base alloy with significant Molybdenum (Mo: 15-17%), Chromium (Cr: 14.5-16.5%), and Tungsten (W: 3-4.5%). Low in Carbon (C) and Silicon (Si) to resist carbide precipitation.

• Key Mechanical Properties: Excellent tensile and yield strength at both room and elevated temperatures. Outstanding fatigue strength and good ductility.

• Primary Applications: The most versatile corrosion-resistant Hastelloy nut bolt solution. Perfect for flue gas desulfurization systems, pulp and paper digesters, waste incineration, and chemical processing equipment handling chlorides, solvents, and oxidizing acids.

2. Hastelloy C22 Bolts

• Chemical Composition (Typical): Enhanced version with a balanced composition of Nickel (Ni), Chromium (Cr: 20-22.5%), Molybdenum (Mo: 12.5-14.5%), and Tungsten (W: 2.5-3.5%). Higher chromium provides superior oxidation resistance.

• Key Mechanical Properties: Similar high strength to C276, with exceptional thermal stability and weldability without post-weld heat treatment.

• Primary Applications: Ideal for severe chemical environments, especially those containing mixed acids (e.g., sulfuric, nitric) and acidic chlorides. Used in pharmaceutical, pickling, and acid production plants.

3. Hastelloy B2 Bolts & Hastelloy B3 Bolts

• Chemical Composition (Typical): Nickel-Molybdenum alloys. B2 has high Molybdenum (Mo: ~28%) and low Iron (Fe). B3 is an improved version with better thermal stability and resistance to grain boundary precipitation.

• Key Mechanical Properties: High strength and excellent creep rupture strength at high temperatures. Maintains ductility in welded conditions.

• Primary Applications: Designed for extreme reducing conditions. The go-to Hastelloy bolts for handling hydrochloric acid at all concentrations and temperatures, sulfuric acid, acetic acid, and other non-oxidizing media. Essential in chemical synthesis and acid recovery systems.

4. Specialty Hastelloy Fasteners

• Hastelloy U Bolts & Anchor Bolts: Manufactured from the above grades to provide secure clamping and structural anchoring in corrosive settings like piping supports, tank bases, and marine installations.

• Hastelloy Nut & Hastelloy C276 Nuts: Precision-matched Hastelloy nuts ensure galvanic compatibility, preventing thread galling and ensuring the longevity of the entire assembly under stress and corrosion.
