Engineered to ASTM B574 and ASME SB-574 standards, this bolt is a critical component in chemical processing, petrochemical, and waste treatment systems where conventional alloys fail. The hexagonal head design allows easy installation with standard wrenches, while the robust alloy composition ensures reliable performance in aggressive environments, including wet chlorine, sulfuric acid, and molten salts.
1. Unmatched Corrosion Resistance: Hastelloy C-276 resists pitting, crevice corrosion, and stress corrosion cracking in harsh media like 50% boiling sulfuric acid, wet chlorine gas, and seawater at 200°C (392°F). It has a corrosion rate <0.025 mm/year in 10% hydrochloric acid at 100°C (212°F).
2. High-Temperature Strength: Maintains tensile strength of 750 MPa (108,800 PSI) at 500°C (932°F) and is oxidation-resistant up to 1200°C (2192°F), making it suitable for furnace fittings, reactor internals, and exhaust systems.
3. Precision Threading and Finish: Available in UNC/UNF (ASME B1.1) and metric (ISO 965-1) threads with Class 2A/2B fit, ensuring compatibility with international flanges and valves. The as-machined surface (Ra 6.3μm) can be electropolished for FDA-compliant applications.
4. Non-Magnetic and Biocompatible: Ideal for medical device manufacturing and magnetic resonance imaging (MRI) equipment, as Hastelloy C-276 has a magnetic permeability <1.001.
5. Quality Assurance: Each bolt undergoes 100% ultrasonic testing for internal defects and proof load testing to ASTM F606, with traceability ensured via laser-etched batch numbers and material certificates (3.1B compliant per EN 10204).
• Chemical Processing Plants: Secures flanges, heat exchangers, and pumps handling concentrated sulfuric/nitric acids, wet chlorine, and hydrogen sulfide (H2S) gas.
• Oil and Gas Refineries: Used in sour gas pipelines (H2S-containing) and offshore platforms, resisting chloride-induced stress corrosion in deep-sea environments.
• Waste Incineration Systems: Fastens components in waste-to-energy plants, enduring high-temperature corrosion from fly ash and acidic flue gases.
• Pharmaceutical Manufacturing: Installs stainless steel reactors and mixers in drug synthesis, meeting USP Class VI and FDA 21 CFR Part 177 requirements for direct food contact.
Q: Why choose C276 over other Hastelloy grades?
A: C276 offers the best balance of corrosion resistance in both oxidizing and reducing environments, outperforming C-22 in low-pH sulfuric acid and C-2000 in high-chloride media.
Q: Can these bolts be welded to other metals?
A: Yes, use matching C276 filler wire (AWS A5.14 ERNiCrMo-4) and preheat to 150°C (302°F) to prevent carbide precipitation.
Q: What is the minimum temperature rating for cryogenic use?
A: Hastelloy C-276 remains ductile down to -269°C (-452°F), making it suitable for liquid helium and nitrogen storage systems.
Q: Are there size limitations for custom orders?
A: Standard sizes range from M6 to M100 / 1/4" to 4", with larger diameters (up to 100mm) available via forging, subject to a 50-unit minimum order.
Q: How to clean C276 bolts after exposure to organic solvents?
A: Use isopropyl alcohol or mild detergent; avoid chloride-based cleaners, which may cause stress corrosion cracking over time.
