RAYCHIN LIMITED
Specialist in Alloy 330 Set Screws · UNS N08330 · 1.4886Alloy 330 Set Screws: Secure Locking in Extreme Heat
RAYCHIN LIMITED is a premier manufacturer of Alloy 330 Set Screws. Designed to provide positive gripping and locking in high‑temperature furnace environments, these set screws resist oxidation, carburization, and thermal shock up to 1150°C. Our Alloy 330 set screws are available in all standard point styles: cup, cone, half‑dog, flat, oval, and knurled cup. Drive options include hex socket, slotted, and square head. Manufactured to NAS, AN, MS, ANSI, ASTM, ASME, SAE, API, NACE, ISO, DIN, KS – or fully custom to your drawing.
Alloy 330 Set Screw – Point Styles & Drive Options
We manufacture all common point styles for Alloy 330 set screws to ASME B18.3 (socket set), ASME B18.6.2 (slotted/square head), and ISO 4026‑4029. Diameters from #0 (M1.6) up to 1" (M24), lengths 3mm to 200mm. Full thread only (as standard) or partial thread on request. Custom point angles, knurled cups, and special drive depths available.
International Standards & Global Designations for Alloy 330
Our Alloy 330 Set Screws are manufactured from material meeting these worldwide specifications:
UNS N08330 1.4886 X12NiCrSi35-16 ASTM B408 AMS 5592 AMS 5716 NAS 330 AN 330
Chemical Composition (Weight %) – Alloy 330 (UNS N08330 / 1.4886)
Our Alloy 330 set screws are produced from certified melts conforming to ASTM B408 / A473 limits:
Complete Mechanical Properties – Alloy 330 Set Screws (Solution Annealed)
All set screws are supplied in the solution annealed condition (1038‑1066°C / water quench). Minimum tensile requirements per ASTM B408 / A473 for bar stock used in fasteners:
High Temperature Performance of Alloy 330 Set Screws
Alloy 330 is specifically formulated for elevated temperature service. The following data represent short‑time elevated temperature yield strength (0.2% offset) based on typical annealed condition:
Oxidation resistance: Continuous service in air up to 1150°C (2100°F); excellent resistance to scaling, carburization, and nitriding.
Thermal Stability & Physical Data
Corrosion Resistance of Alloy 330 Set Screws
While Alloy 330 is optimized for high‑temperature environments, it offers good resistance to many corrosive conditions:
- Oxidation & carburization: Exceptional resistance in air, combustion gases, and sulfur‑bearing atmospheres up to 1150°C.
- Nitriding: Good resistance to nitrogen‑rich atmospheres (e.g., cracked ammonia).
- Stress corrosion cracking: High nickel content (34‑37%) provides immunity to chloride SCC.
- Aqueous corrosion: Similar to 310 stainless; suitable for organic acids, but NOT intended for strong reducing acids or chloride pitting environments.
- Oxidizing sulfur: Performs well in oxidizing sulfur; for reducing sulfur consult our engineers.
Precision Manufacturing & Global Standards Compliance
CNC Forming & Heat Treatment
Our Alloy 330 set screws are cold‑headed or CNC machined from solution‑annealed bar stock, then thread rolled for improved grain flow. Each lot undergoes solution annealing (1038‑1066°C) and water quenching to guarantee optimum high‑temperature properties. Point geometry is precision ground to ensure consistent locking torque.
Traceability & Third‑Party Testing
Full traceability from melt to finished product. Certificates EN 10204 3.1/3.2. NDT (PT, MT, UT) available on request. Our quality system: ISO 9001:2015, AS9100D. We also comply with NAS, AN, MS, ANSI, ASTM, ASME, SAE, API, NACE, ISO, DIN, KS, JIS, GB. Custom designs welcome.
Alloy 330 Set Screws – Typical Applications & Industries
Our Alloy 330 set screws are widely used for locking collars, gears, and pulleys in:
- Furnace rollers & conveyor systems
- Heat treating baskets & fixtures
- Radiant tube supports
- Annealing covers & quenching mechanisms
- Gas turbine components
- Petroleum heater dampers
- Exhaust system couplings
- Salt bath furnace electrodes
We also supply matching Alloy 330 nuts, washers, and threaded rods for complete high‑temperature bolting sets.
