Industries We Serve
- Aerospace Bolts & Screws
TSM's titanium bolts secure jet engine components and airframe structures, withstanding 800°C+ thermal cycling. AS9100-compliant screws feature precision threads (±0.05mm) for vibration-resistant performance.
-
Oil & Gas Pipeline Bolts
Corrosion-resistant Monel® bolts maintain seal integrity in sour gas wellheads and subsea valves. Our ASTM A193 B7M screws resist H₂S/CO₂ corrosion at 10,000 PSI pressures.
-
Nuclear Power Fastening Systems
Grade B7 alloy steel bolts anchor reactor vessel flanges with full traceability per ASME III. Zirconium alloy screws minimize neutron absorption in fuel assemblies.
-
Chemical Processing Screws
Hastelloy® C276 bolts prevent acid leakage in reactors and heat exchangers. PTFE-coated screws handle chlorine/alkali exposure with ASTM F594 certification.
-
Marine & Desalination Bolts
Super duplex stainless steel screws resist saltwater pitting in ship engines and desal pumps. Anodized titanium bolts deliver 20+ year service in seawater immersion.
Production and Package
FAQ
Q: How does VIM/ESR improve bolt performance in corrosive environments?
A: Vacuum Induction Melting (VIM) + Electroslag Remelting (ESR) ensures Ni ≥ 99.6% purity (ASTM B160), O₂ ≤ 80ppm, N₂ ≤ 50ppm. Eliminates inclusions for sour gas/pipeline corrosion resistance.
Q: Can TSM produce non-standard screw geometries?
A: Yes. We prototype complex bolt/screw structures (e.g., flanged heads, asymmetric threads) in 3 weeks. 5-axis CNC enables ±0.05mm precision for R&D validation.
Q: What certifications do TSM bolts and screws meet?
A: All fasteners exceed ASTM/ASME, EN, and DIN standards with full traceability. Batch-tested for nuclear, subsea, and turbine applications.
Q: Are your titanium bolts suitable for seawater immersion?
A: Absolutely. Our Grade 5/23 titanium bolts resist galvanic corrosion in marine/desalination systems. Validated for 20+ year service life per ASTM F468.
