1. What are the key properties of Inconel C22 (N10065) and Hastelloy B2/B3 round bars?
Answer:
Inconel C22 (N10065): Nickel-chromium-molybdenum-tungsten alloy with outstanding resistance to oxidizing and reducing environments, strong corrosion resistance to acids, and excellent high-temperature stability.
Hastelloy B2/B3: Nickel-molybdenum alloys with exceptional resistance to hydrochloric acid and other strong reducing chemicals. B3 has improved fabrication characteristics and enhanced corrosion resistance compared to B2.
Both alloys maintain strength, toughness, and dimensional stability in extreme chemical environments.
2. What sizes and dimensions are available for these round bars?
Answer:
Diameters: Typically range from 6 mm up to 300 mm
Lengths: Standard lengths 1 m, 2 m, or cut-to-size as requested
Custom diameters and tolerances are often available depending on the mill and processing method
Cold-drawn and hot-rolled bars are offered to meet different surface finish and precision requirements
3. Can these nickel-based alloy bars be welded or machined?
Answer:
Welding: TIG, MIG, and electron beam welding are suitable for these alloys. Using compatible filler metals and following post-weld heat treatment when necessary ensures structural integrity.
Machining: These high-purity nickel alloys work-harden quickly. Carbide or ceramic tooling, controlled feed rates, and sufficient coolant are recommended for precise machining.
4. Which industries commonly use Inconel C22 and Hastelloy B2/B3 round bars?
Answer:
Chemical & Petrochemical: Reactors, piping, heat exchangers, and valves exposed to aggressive chemicals
Pharmaceutical & Food Processing: Corrosion-resistant equipment for acid handling
Power Generation: High-temperature and high-pressure components
Marine & Offshore: Equipment exposed to seawater and harsh environments
Their high corrosion resistance and chemical stability make them ideal for extreme environments.
5. What certifications and quality standards are available for these bars?
Answer:
Material Certification: Mill Test Reports (MTRs) per ASTM B574 (Hastelloy B2/B3) and ASTM B575 (Inconel C22)
Testing: Chemical analysis, mechanical property testing, dimensional inspection, and optional NDT (ultrasonic or eddy current)
Standards Compliance: ASTM, ASME, ISO 9001, and NACE MR0175/ISO 15156 for sour service
Custom certifications can also be provided upon request for project-specific requirements.
