| Mechanical Strength | High without heat treatment |
Average Alloy 625 Plate Price Range
Price by Unit
| Unit | Price Range | Description |
|---|---|---|
| USD/kg | $80 – $140 | Depends on thickness and processing |
| USD/ton | $80,000 – $140,000 | Bulk industrial pricing |
Price Differences by Thickness and Size
Thickness Impact
Thicker plates generally have lower cost per kilogram due to easier rolling processes, while thin precision plates are more expensive due to tighter tolerances.
| Thickness Range | Price Level |
|---|---|
| < 6 mm | Higher |
| 6 – 20 mm | Medium |
| > 20 mm | Lower per kg |
Hot Rolled vs Cold Rolled Alloy 625 Plate Price Comparison
| Process | Price Level | Characteristics |
|---|---|---|
| Hot Rolled | Lower | Standard industrial applications |
| Cold Rolled | Higher | Better surface finish and precision |
Annealed vs Solution Treated Plate Cost Differences
| Condition | Cost Level | Description |
|---|---|---|
| Annealed | Medium | Improved ductility |
| Solution Treated | Higher | Enhanced corrosion resistance and strength |
Nickel Content Impact on Plate Price
Nickel accounts for the largest portion of Alloy 625 cost. With nickel content exceeding 58%, fluctuations in nickel market prices significantly affect overall plate pricing.
Surface Finish and Cost Differences
| Finish | Cost Level |
|---|---|
| No.1 (Hot Rolled) | Lowest |
| 2B Finish | Medium |
| Polished | Highest |
ASTM & ASME Standards Impact
| Standard | Impact |
|---|---|
| ASTM B443 | Defines quality requirements for plates |
| ASME SB443 | Required for pressure vessel applications |
Manufacturing Process Cost
Key Steps
- Vacuum melting for high purity
- Hot rolling or cold rolling
- Heat treatment (annealing or solution treatment)
Each step adds to the final cost due to energy consumption and technical requirements.
Global Nickel Market (LME) Influence on Pricing
The London Metal Exchange (LME) nickel price directly impacts Alloy 625 plate pricing. Sudden fluctuations in nickel prices can significantly change supplier quotations.
Regional Price Differences
| Region | Price Level | Reason |
|---|---|---|
| China | Lower | Large-scale production and lower costs |
| India | Competitive | Growing manufacturing base |
| USA | High | Strict certification and labor cost |
| Europe | High | Quality and compliance requirements |
