Product Overview

RAYCHIN LIMITED supplies a comprehensive range of high-performance 17-4PH fasteners, engineered from precipitation-hardening martensitic stainless steel. Our products include 17-4PH hex bolts, 17-4PH socket head cap screws, 17-4PH stud bolts, 17-4PH double end studs, 17-4PH nuts (including heavy hex nuts), and 17-4PH washers. These fasteners are manufactured under strict quality control and comply with international standards such as GB, ISO, DIN, ANSI/ASME, and JIS.

Key features of 17-4PH fasteners include:

· High Strength: Tensile strength up to 1100-1300 MPa after heat treatment.

· Corrosion Resistance: Suitable for atmospheric, dilute acid, and salt environments, with performance comparable to 304 and 430 stainless steels.

· Temperature Resilience: Effective for use up to 300°C (572°F).

· Customizability: Available in standard and non-standard sizes (e.g., M1.6–M64 for screws, M8–M120 for bolts), with tailored specifications based on customer drawings or samples.

Applications Across Industries

17-4PH fasteners are ideal for critical applications where reliability under stress and corrosive conditions is essential. Key sectors include:

· Nuclear Power: Reactors, waste containers, and structural components.

· Oil & Gas: Petrochemical equipment, pressure vessels, pipelines, and offshore platforms.

· Aerospace: Turbine blades, engine parts, and airframe assemblies.

· Heavy Machinery: Papermaking equipment, pumps, valves, and power generation systems.

· Marine and General Industry: Helicopter decks, food processing, and paper pulp machinery.

Key Considerations for Application

To ensure optimal performance of 17-4PH fasteners, consider the following factors:

1. Heat Treatment Requirements: Mechanical properties vary with aging temperature (e.g., 480°C aging achieves tensile strength ≥1310 MPa, while 620°C aging provides better elongation ≥16%). Select the appropriate treatment based on strength-corrosion trade-offs.

2. Temperature Limits: Avoid prolonged use above 300°C (572°F) to prevent material degradation.

3. Corrosive Environment: While resistant to mild oxidizers and salts, avoid exposure to chlorides or reducing acids to minimize pitting or stress corrosion cracking.

4. Dimensional Standards: Ensure compatibility with assembly specifications (e.g., ISO 4014, DIN 931, ANSI B18.2.1).

5. Galling Prevention: Use anti-seize lubricants during installation, as 17-4PH alloys may be prone to thread seizure.
