AL6XN Fasteners: Hex Bolts, Studs, Nuts, Washers & Threaded Rod in 6Mo Super Austenitic Stainless Steel
For environments that demand the ultimate pitting and crevice corrosion resistance at a cost below nickel‑base alloys, AL6XN fasteners are the definitive solution. This 6Mo super austenitic stainless steel provides a PREN of 44–46—nearly double that of 316L—making it the material of choice for warm seawater, bleach, and acidic brine applications. RAYCHIN LIMITED, a specialist global manufacturer and supplier of high‑performance alloy fasteners, produces the complete line of AL6XN hex bolts, stud bolts, socket head cap screws, heavy hex nuts, washers, and threaded rod. This catalog details every product form, dimensional capability, and quality standard we offer.
1. AL6XN Fastener Product Forms
? AL6XN Hex Bolts
AL6XN hex bolts are manufactured to ASME B18.2.1, DIN 931/933, and ISO 4014. Available in partial and full thread, sizes from 1/4″ to 2″ and M6 to M48. Ideal for seawater piping flanges, bleach plant equipment, and chemical reactor bolting.
? AL6XN Stud Bolts
AL6XN stud bolts include double‑end studs (ASME B16.5) and fully threaded studs (ASME B18.31.2, DIN 976). Diameters from 1/4″ to 2‑1/2″ and M6 to M64. Lengths up to 3 meters. Rolled threads for enhanced fatigue life and galling resistance.
? AL6XN Socket Head Cap Screws
AL6XN socket head cap screws per ASME B18.3 provide compact, high‑torque fastening for confined spaces. Sizes from #4 to 1″ and M3 to M24. Common in valve actuator mounts and instrumentation brackets.
? AL6XN Heavy Hex Nuts
AL6XN heavy hex nuts per ASME B18.2.2 and DIN 934 are proof‑load matched to the corresponding bolt or stud. All‑metal prevailing‑torque lock nuts are also available for vibration‑resistant applications.
⬜ AL6XN Washers
AL6XN washers—flat per ASME B18.22.1 / DIN 125 and spring lock per DIN 127—match bolt diameters from 1/4″ to 2″ and M6 to M48. Custom outside diameters and thicknesses are available.
? AL6XN Threaded Rod
AL6XN threaded rod (continuous‑thread studding) is cut to your specified length with chamfered ends. Diameters from 1/4″ to 2‑1/2″ and M6 to M64. Full lot certification and PMI testing included.
2. AL6XN Flanged Bolts and Custom Configurations
AL6XN flanged bolts integrate a washer‑like bearing surface under the head, distributing clamp load without a separate washer. RAYCHIN manufactures these to your custom dimensions—head diameter, flange thickness, under‑head fillet radius—as well as stepped studs, reduced‑shank bolts, and body‑bound fasteners from your CAD drawings.
3. AL6XN Fasteners Dimensions: Metric and Imperial
AL6XN metric bolts and AL6XN imperial bolts are fully covered—RAYCHIN maintains tooling and inventory for both measurement systems. Simply specify the thread standard and dimensions on your RFQ.
4. Quality Assurance and Certification
Every AL6XN fastener shipment from RAYCHIN includes:
- Material certification to ASTM A182 (UNS N08367)
- EN 10204 Type 3.1 certificate (Type 3.2 with independent third‑party witness on request)
- Positive Material Identification (PMI) report—OES analysis on finished fasteners
- Mechanical test report: tensile, yield, elongation, and hardness
