Why Choose TorqBolt as Your Incoloy 925 Supplier
- Domain expertise: Specialised CRA bolting manufacturer, not a general fastener distributor. We understand the metallurgical, sour-service and HPHT requirements that drive Incoloy 925 specifications.
- Direct manufacturing: In-house heat treatment (calibrated nitrogen-atmosphere ageing furnaces with continuous chart-recorder traceability per AMS 2750), threading, machining and NDE. No middleman lead time.
- Mill QTRs: Material sourced from approved primary mills (Special Metals, Sandvik, VDM, ATI) with mill MTCs documenting heat chemistry. NORSOK M-650 mill qualifications maintained current with 180/90/60/30-day re-qualification alerts.
- Full traceability: Heat number stamped on every piece pre-treatment; barcoded movement through anneal → quench → age sequence; chart-recorder traces archived 5 years ASTM B805 Section 7.
- 100% hardness inspection: Every piece tested per ASTM E18 with values reported on MTC, ensuring 35 HRC NACE sour-service cap is never exceeded.
- Sample mechanical + Charpy: Per heat / per heat-treatment lot per ASTM B805; -46°C and -101°C Charpy on request for API 6A PSL-3G cryogenic / sour-service applications.
- Global logistics: CIF / FOB / DDP terms; air freight 5–7 days, sea freight 25–40 days from Mumbai to most oilfield hubs.

Lead Times
| Product Category | Standard Lead Time | Expedited Option |
|---|---|---|
| Stud bolts (1/4" to 2", aged) | 4–6 weeks | 2–3 weeks (subject to bar stock) |
| Stud bolts (2" to 4", aged) | 6–8 weeks | 4–5 weeks |
| Bar stock (round, hex) | 4–6 weeks ex-stock; 8–10 weeks new-melt | 2–3 weeks for held sizes |
| Forgings (open-die, simple) | 8–12 weeks | 6–8 weeks |
| Forgings (closed-die, complex) | 12–16 weeks | 10–12 weeks |
| Plate / sheet | 8–12 weeks | 6–8 weeks for held sizes |
| Pipe / tube (welded) | 10–14 weeks | 8–10 weeks |

Frequently Asked Questions
Is TorqBolt a manufacturer or a stockist? Both. We hold standard sizes of bar / billet ex-stock and convert to finished products in our Mumbai / Rajkot manufacturing operations. For non-standard sizes or large orders, we melt-to-order through approved primary mill partners.
What's the minimum order quantity? No fixed minimum, we quote single-piece orders and 100,000-piece orders alike. Pricing scales with quantity; for quantities below 50 kg, expect ~25% premium over standard volume pricing due to setup overhead.
Can TorqBolt quote against client-approved manufacturer lists? Yes, we maintain registrations / approvals with major operators and EPCs (Aramco AMC, ADNOC, Petronas, Equinor, Cameron CMP, Dril-Quip, etc.). Send your AML number and we'll confirm registration status.
What payment terms are available? Standard: 30% advance / 70% on shipment, telegraphic transfer (TT). Letters of credit (LC) accepted for orders over USD 50,000. Net 30 / Net 60 / Net 90 available for established customers with credit history.
How do I verify TorqBolt's quality system? ISO 9001:2015 certificate available on request. NORSOK M-650 qualification certificate, NACE MR0175 stamping authority, and individual mill QTRs all available pre-order. We welcome customer audit visits to our Mumbai or Rajkot facility.
