Product Description

 

Product Description

Hastelloy C-276 Ring is a high-performance nickel-chromium-molybdenum alloy ring designed for extreme corrosion environments. It offers outstanding resistance to strong acids, including sulfuric acid, hydrochloric acid, phosphoric acid, and mixed acid media, even under high temperature and high pressure conditions.

This alloy exhibits excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, making it an ideal material for critical sealing and structural components in chemical processing, petrochemical, oil & gas, and environmental industries.

Hastelloy C-276 rings can be supplied in forged, machined, or customized forms, with strict quality control and full material traceability to meet international standards.

Key Features:

• Excellent resistance to sulfide stress cracking (SSC) and chloride-induced pitting and crevice corrosion

• High strength due to age-hardening (precipitation strengthening)

• Resistant to oxidizing and reducing acids

• Good ductility and toughness

• Outstanding corrosion resistance in HS, CO, and chloride environments

Typical Applications:

• Oil and gas well tubulars

• Valves, hangers, and subsurface safety equipment

• Marine and offshore components

• Chemical processing and pollution control systems

• High-strength fasteners and connectors

FAQ

 

Q1: What makes INCOLOY 925 special compared to INCOLOY 825?
A1: While both have similar corrosion resistance, INCOLOY 925 is age-hardenable, offering much higher strength, making it ideal for oilfield and high-pressure applications.

Q2: What environments can INCOLOY 925 withstand?
A2: It resists corrosion and stress cracking   CO2, chlorides, and brine environments, especially in sour gas wells and subsea systems.

Q3: Can INCOLOY 925 be welded and heat treated?
A3: Yes. It can be welded using standard nickel alloy techniques and age-hardened after fabrication to restore strength.

Q4: What forms are available?
A4: Bars, rods, rings, tubes, pipes, forgings, and custom machined parts.

Q5: What certifications can be provided?
A5: All materials can be supplied with EN 10204 3.1 / 3.2 certificates, including NACE MR0175 compliance for sour service.

A6: Yes, EN 10204 3.1 / 3.2 certificates are available, including full chemical analysis and mechanical test reports.

Q7: What is the delivery time?
A7: Usually 7-15 working days for stock materials, and 20-30 days for custom-machined or special-size rings.

Q8: Do you offer price discounts for large quantities?
A8: Yes. We provide big price discounts for bulk orders or long-term cooperation projects. Please contact us for a detailed quotation.
