Quick answer: Inconel 600 sheet mechanical properties depend on thickness, delivery condition, cold work, heat treatment, specimen orientation and test temperature. Manufacturer literature gives useful typical annealed room-temperature values—about 655 MPa tensile strength, 310 MPa 0.2% yield strength and 40% elongation—but purchase acceptance should follow the ordered edition of ASTM B168, ASME SB-168 or the project specification.
Buyers should separate typical reference data from guaranteed order limits. The Inconel 600 sheet and plate product page describes the commercial product; the purchase order should define the exact standard, thickness, condition and tests.
Typical Data vs Purchase Acceptance
| Property | Typical annealed reference | What controls acceptance |
|---|---|---|
| Tensile strength | Approximately 655 MPa | The ordered standard, thickness range, condition and test method |
| 0.2% yield strength | Approximately 310 MPa | Specification minimum, specimen orientation and test temperature |
| Elongation | Approximately 40% | Gauge length, specimen geometry, thickness and governing document |
| Hardness | Varies with annealing and cold work | Specified scale, maximum/minimum if applicable, and sampling |
| Elevated-temperature strength | Not represented by room-temperature tensile values | Design code, temperature, time, stress and product condition |
The typical values above summarize manufacturer literature; they are not a certificate for a particular heat or sheet. The active ASTM B168 scope covers N06600 plate, sheet and strip and includes chemical, dimensional and mechanical requirements. State the required revision because standard requirements can change.
How Condition Changes Properties
| Condition factor | Expected effect | RFQ instruction |
|---|---|---|
| Annealing | Reduces cold-work strengthening and restores ductility | Name the required annealed condition through the governing specification |
| Cold work | Can increase strength and hardness while reducing ductility | Specify temper or property limits; do not order only by appearance |
| Section thickness | Affects processing and applicable test requirements | State nominal thickness and tolerance |
| Test temperature | Changes strength and ductility response | State whether room-temperature or elevated-temperature data are required |
| Welding/forming history | Can alter local properties and residual stress | Define whether acceptance applies to mill product or fabricated component |
What ASTM B168 Does—and Does Not—Tell the Buyer
ASTM B168 is a material/product specification for covered nickel-alloy plate, sheet and strip. It provides a common basis for composition, dimensions and mechanical testing, but it does not automatically select a design thickness, corrosion allowance, welding procedure or pressure rating. Those belong to the equipment design and applicable construction code.
- State ASTM B168 or ASME SB-168 and the project-approved revision.
- Use UNS N06600 to identify the alloy grade.
- Define sheet versus plate, nominal thickness, width, length and tolerances.
- State delivery condition and surface requirements.
- List tensile, hardness, dimensional and additional test acceptance explicitly.
- Request the required certificate type and heat/lot traceability without claiming tests that were not ordered.

Frequently Asked Questions
Are the typical 655/310 MPa values guaranteed for every sheet? No. They are reference values from manufacturer literature. The ordered ASTM/ASME edition, thickness, condition and actual test certificate control acceptance.
Will properties remain unchanged after forming or welding? Not necessarily. Cold work, local heating, weld thermal cycles and subsequent heat treatment can change the local condition. Fabricated-component acceptance should be defined separately from mill-sheet acceptance.
Conclusion
Use typical Inconel 600 sheet properties to compare materials, not to replace the purchase specification. The reliable path is to state UNS N06600, the governing ASTM/ASME or project document, dimensions, condition, required properties, inspection and downstream fabrication needs.
