Material identity control: SA-266 is the carbon-steel pressure-vessel forging designation shown in the product title and specification table. The separate 42CrMo4 reference is an alloy-steel grade. Do not substitute one for the other without an approved engineering change and revised material documentation.
SA-266 Chemical Composition Reference
The product page reproduces the following composition limits under ASTM/ASME SA-266/SA-266M. These are reference limits from the listing, not a heat analysis or a test result for a delivered forging.
| Element | Classes 1 & 2 | Class 3 | Class 4 |
|---|
| Carbon (C), max. | 0.30% | 0.35% | 0.30% |
| Manganese (Mn) | 0.40–1.05% | 0.80–1.35% | 0.80–1.35% |
| Phosphorus (P), max. | 0.025% | 0.025% | 0.025% |
| Sulfur (S), max. | 0.025% | 0.025% | 0.025% |
| Silicon (Si) | 0.15–0.35% | 0.15–0.35% | 0.15–0.35% |
Confirm governing edition, selected class, supplementary requirements and actual heat chemistry against the material test certificate. This summary is not a substitute for the standard or certified heat analysis.

Procurement Due-Diligence Checks
- Match exporter legal name, address and aliases to contracting entity and bank beneficiary.
- Confirm whether cited shipment concerned forged rings, SA-266 material and comparable dimensions.
- Request redacted commercial evidence where appropriate, including bill of lading and invoice.
- Validate current certificates and scope independently with issuing organizations.
- Confirm ITP, MTC traceability, NDT reports and third-party witness requirements before shipment.
Trade records are selective public database snapshots, not a complete shipping history and not verification of this specific product. Name variants, related entities and database coverage may affect matching.

Frequently Asked Questions
1. Can the supplier manufacture a ring to a custom drawing?
The product is listed as an OEM customized forged ring, with rough or finish machining. Submit an approved drawing showing OD, ID, height, machining allowances, tolerances, material grade and inspection requirements.
2. Is the minimum order quantity fixed?
The listing states MOQ is negotiable. Confirm minimum chargeable quantity, batch size, setup costs and material procurement constraints in the quotation.
3. How should SA-266 material and grade be specified?
State ASTM/ASME SA-266/SA-266M, required class, governing edition and supplementary requirements. 42CrMo4 is a separate alloy-steel grade and must not be treated as interchangeable.
4. What dimensional tolerance can be expected?
The listing states ±0.1 mm and Ra 3.2 μm or as required. Confirm whether tolerance applies to forged or final machined dimensions, and identify controlled features on the drawing.
5. What inspection documents should be agreed?
Define MTC / heat analysis, mechanical test results, heat-treatment records, dimensional report and UT, MT or PT examination as applicable. Agree standards, coverage, acceptance criteria and witness points in the ITP.
6. How is the forging protected for sea transport?
The listing identifies seaworthy wooden cases or iron / steel pallets, or customer-specified packing. Specify corrosion protection, moisture barrier, impact protection, lifting points and package marking.
7. What is the production lead time?
A fixed lead time is not published. Request a project schedule after grade, drawing, quantity, heat-treatment route, machining, inspection and shipping terms are agreed.
8. What should be checked before accepting the order?
Verify legal entity and bank details, current certificate validity and scope, approved drawing revision, material traceability, inspection documents, packaging and shipment records. For pressure-vessel service, the design authority should confirm code and material compliance.
