RAYCHIN LIMITED: Engineered Excellence in Hastelloy C22 Fasteners for Extreme Environments

Comprehensive Product Range of Hastelloy C22 Fasteners

RAYCHIN LIMITED supplies a full spectrum of corrosion-resistant Hastelloy C22 fasteners, designed to withstand the most aggressive industrial environments. Our product portfolio includes:

· Hastelloy C22 Hex Bolts & Stud Bolts: Available in thread sizes from M6 to M100 and lengths from 30mm to 800mm, compliant with ISO 4014, DIN 931, and ANSI B18.2.1 standards .

· Hastelloy C22 Nuts: Precision-engineered hexagonal nuts (sizes M5–M100), conforming to GB/T 6170, DIN 934, and ISO 4032 .

· Hastelloy C22 Socket Head Screws: Featuring low-profile designs for space-constrained applications, such as SSHH-M5-C22 (ultra-low head) and SNSH-M8-C22 for cleanroom use .

· Hastelloy C22 Washers & Custom Fasteners: Tailored dimensions and specifications based on client drawings or samples.

Critical Applications Across Industries

Hastelloy C22 fasteners deliver unmatched performance in sectors where failure is not an option:

· Chemical & Petrochemical Processing: Reactors, heat exchangers, and piping systems exposed to mixed acids (e.g., sulfuric, acetic) and chlorides .

· Semiconductor & FPD Manufacturing: Etching equipment, surface treatment devices, and cleanroom assemblies requiring resistance to plasma and acidic vapors .

· Oil & Gas: Offshore platforms, wellhead components, and scrubbers in sour gas (H₂S) and seawater environments .

· Pollution Control & Energy: Flue gas desulfurization (FGD) systems, incinerators, and geothermal wells .

· Marine Engineering: Pump shafts, valve trim, and structural components in saltwater and brine applications .

Key Selection Factors for Optimal Performance

When integrating Hastelloy C22 fasteners, consider these factors to ensure reliability:

1. Corrosive Media Compatibility:

· Excels in both oxidizing (e.g., nitric acid) and reducing (e.g., sulfuric acid) environments .

· Highly resistant to pitting, crevice corrosion, and stress corrosion cracking (SCC), even in chloride-rich settings .

2. Temperature Resilience:

· Maintains mechanical properties from cryogenic temperatures up to 1370°C .

3. Mechanical Strength Requirements:

· Minimum tensile strength of 690 MPa and yield strength of 283 MPa in solution-annealed condition .

4. Dimensional & Standards Compliance:

· Verify thread tolerances (e.g., 6G for bolts) and alignment with international standards (e.g., ASTM B574) .

5. Galling Prevention:

· Use anti-seize lubricants during installation, as nickel alloys are prone to thread galling under friction.
