Comprehensive Product Range of SUS 630 Socket Cap Screws

At RAYCHIN LIMITED, we specialize in manufacturing premium SUS 630 hex socket cap screws (also known as 17-4PH stainless steel fasteners), designed to deliver exceptional strength and corrosion resistance. 

Our product portfolio includes:

1. Standard Hex Socket Cap Screws: Compliant with DIN 912/ISO 4762 standards, available in sizes from M5 to M48 and lengths from 16mm to 1000mm .

2. High-Strength P1-90 Grade Screws: Optimized for critical applications, with tensile strength reaching 900–1300 MPa and hardness up to 40 HRC .

3. Custom Socket Cap Screws: Tailored specifications, including non-standard lengths, fine/coarse threads, and special head configurations based on client drawings or samples.

Critical Applications Across Industries

SUS 630 Socket Cap Screws are engineered for resilience in extreme environments:

· Aerospace & Defense: Turbine blades, engine mounts, and structural components requiring high strength-to-weight ratios .

· Oil & Gas: Offshore platforms, wellhead equipment, and valves exposed to H₂S environments and seawater corrosion .

· Chemical Processing: Reactors, pumps, and piping systems handling acidic media or chloride-containing solutions .

· Heavy Machinery: High-stress components in papermaking equipment, hydraulic systems, and power generation turbines .

· Automotive & Racing: Turbocharger assemblies, exhaust systems, and suspension components demanding fatigue resistance .

Key Selection Factors for Optimal Performance

When integrating SUS 630 Socket Cap Screws, consider these factors to ensure reliability:

1. Mechanical Strength Requirements:

· Tensile strength ranges from 930 MPa to 1310 MPa, depending on heat treatment (e.g., 480°C aging achieves ≥1310 MPa) .

· Yield strength varies between 725 MPa and 1180 MPa, select based on load-bearing needs .

2. Corrosion Resistance:

· Resists atmospheric conditions, dilute acids, and salts, with performance comparable to 304/430 stainless steels .

· Avoid prolonged exposure to reducing acids or chlorides to prevent pitting .

3. Temperature Limitations:

· Suitable for cryogenic to 300°C (572°F) continuous service; higher temperatures may reduce hardness .

4. Heat Treatment Compatibility:

· Options include H900 (482°C) to H1150 (621°C) aging, balancing strength (e.g., H900: ≥1340 MPa tensile) and toughness .

5. Installation Best Practices:

· Use anti-seize lubricants to prevent galling during torque application .

· Ensure thread fit aligns with standards like ISO 965 for secure fastening.
