Q1: What is Hastelloy C276 and what are its main characteristics?
A1: Hastelloy C276 is a nickel-molybdenum-chromium alloy with excellent corrosion resistance. It is highly resistant to oxidizing and reducing chemicals, including strong acids and chlorides. C276 also offers outstanding resistance to pitting, stress-corrosion cracking, and crevice corrosion.
Q2: What are the typical applications of Hastelloy C276 round rods?
A2: C276 round rods are commonly used in chemical processing equipment, marine engineering, wastewater treatment, flue gas scrubbers, and nuclear industry components. They are ideal for manufacturing pumps, valves, heat exchangers, and other equipment exposed to aggressive chemicals.
Q3: What temperature ranges can Hastelloy C276 withstand?
A3: Hastelloy C276 performs reliably at temperatures up to approximately 1100 ℃ (2010 ℃F) in oxidizing environments. It maintains mechanical strength and corrosion resistance in both high-temperature and high-pressure applications.
Q4: What are the mechanical properties of Hastelloy C276 round rods?
A4: Typical properties include:
Tensile strength: ~760 MPa
Yield strength (0.2% offset): ~350 MPa
Elongation: ~40%
Hardness: ~90 HRB
These properties make it durable and reliable for industrial bar applications under harsh operating conditions.
Q5: How can Hastelloy C276 rods be processed or fabricated?
A5: Hastelloy C276 rods can be machined, cold-worked, or formed into industrial components. Welding is possible using TIG, MIG, or shielded metal arc welding. Post-weld cleaning is recommended to maintain corrosion resistance. The rods are typically supplied in solution-annealed condition for optimal performance.
