Selected elements only, not the complete composition specification. “≥” is a published minimum; “≤” is a published maximum. Nominal values describe a material, not acceptance limits. Use the complete agreed specification for purchase and the actual heat analysis for release.
Composition source ↗Bar Standards & Specifications
| Bar specification reference | ASTM B574 / ASME SB574 |
|---|---|
| Forgings | ASTM B564 / ASME SB564; separate purchase form. |
| Edition & acceptance | State the required edition, material condition, dimensions and supplementary requirements in the RFQ. |
The applicable standard depends on the product form, dimensions and delivery condition. Confirm the edition and any supplementary requirements when ordering; standards for other product forms may not apply to bars.
Standard reference source ↗For IGC, state whether you require intergranular corrosion testing and give the method. For NACE or API requirements, include the document, edition, clauses, material state and service conditions.
Standards & inspection scope →Mechanical properties & delivery condition
Specify solution-annealed stock and any supplementary corrosion-test requirements.
| Material / condition / test temperature | Tensile strength, MPa | 0.2% proof / yield strength, MPa | Elongation, % | Data basis |
|---|---|---|---|---|
| Bar, 12.7–50.8 mm; solution annealed; room temperature | 765 | 359 | 70 | Haynes, average test data |
Published values apply to the stated test conditions and sample sizes. They are provided for reference, not as guaranteed batch results or design allowables. Your order specification defines acceptance requirements.

|---|---|
| Purchase acceptance | Requirements in the agreed specification, edition and approved order. |
| Delivered batch | Actual results linked to the supplied heat or lot in its quality documents. |
Dimensions, finish & supply requirements
| Round-bar dimensions | Specify diameter × length, units, dimensional tolerances and straightness. The general 1–300 mm diameter reference does not confirm every Alloy C-22 size or condition. |
|---|---|
| Heat-treatment condition | Specify solution-annealed stock and any supplementary corrosion-test requirements. |
| Surface & allowance | Request turned, peeled, ground or other finish with surface criteria and machining/cutting allowance. The quotation confirms the available route. |
| Quantity & schedule | Give kg or pieces, split lengths and required date. General references of 100 kg and 40 days are subject to order confirmation. |
| Packing & identification | Specify crate/bundle requirements, heat or piece identification and delivery destination. |

Applications & Component Requirements
Corrosive-process machined components and valve-part enquiries; assess oxidizing/reducing conditions and contaminants.
For a quotation, provide the approved drawing, required bar size, delivery condition, quantity, destination and inspection requirements. Our factory reviews production feasibility before confirming the order.
Industry guides organize RFQ requirements. Final material selection must follow the approved engineering specification and actual service conditions.
Material application reference ↗Inspection, traceability & quality documents
| Material evidence | Specify complete heat analysis, required mechanical tests and the agreed delivery condition. |
|---|---|
| Additional inspection | State NDT or corrosion-test method, sampling, coverage, specimen condition and acceptance criteria. Laboratory accreditation covers only its listed methods. |
| Release documents | Identify the certificate type, including EN 10204 Type 3.1 or 3.2 when required, and any third-party arrangements for review. |
| Traceability | Connect material marking, heat/lot identity and documents. Specify piece-level marking where needed. |
Alloy C-22 purchasing questions
Can you manufacture Alloy C-22 round bar in China?
Yes. Jiangsu Xinhua Alloy manufactures nickel alloy bars in its own factory. Send the grade, dimensions, quantity, delivery condition and inspection requirements for a feasibility review and quotation.
Which specification should I put on my Alloy C-22 RFQ?
ASTM B574 / ASME SB574. Identify the edition, purchased form and required condition; any additional drawing or customer specification needs to be included.
Which delivery condition should I request?
Specify solution-annealed stock and any supplementary corrosion-test requirements.
Can I order this grade in square, flat, hexagonal or forged-bar form?
Submit the form, dimensions and condition for a feasibility review. Listing this grade as round bar does not confirm another section, forged route or size.
Are published properties guaranteed for my order?
No. Literature data, purchase acceptance criteria and actual heat/lot results are separate. The quotation and quality documents establish the agreed order requirements.
