PRODUCT OVERVIEW
About Inconel 625 Plate and Sheet
Southerly Alloy supplies Inconel 625 plate and sheet in UNS N06625 and Werkstoff 2.4856, a nickel-chromium-molybdenum-niobium grade hardened by solid solution. Flat-rolled product runs to ASTM B443 in both grades. Typical duty covers scrubber liners and vessel internals, for example.
Buyers normally arrive here after settling the thickness and condition, because those two choices fix the rolling route. The full chemistry, standards, and grade logic sit on the Inconel 625 material page, while their own form pages cover bar and rod and pipe and tube supply.
PRODUCT FEATURES
Key Features of Inconel 625 Plate and Sheet
Southerly Alloy supplies UNS N06625 plate and sheet to ASTM B443 / ASME SB443 in hot-rolled plate, cold-rolled plate, sheet, and strip, in both Grade 1 and Grade 2 conditions. Thickness runs from 0.5 mm foil stock through 100 mm plate, cut to size by plasma, laser, or waterjet, with EN 10204 3.1 certificates on every order. We quote cut-to-size blanks, circles, and rings from the same inquiry as full plates.
Inconel 625
Thickness Coverage Without Gaps
We quote strip, sheet, and plate from 0.13 mm to 100 mm so a project does not split across suppliers.
01
Chloride Pitting Resistance
Chromium, molybdenum, and niobium hold the flat product against seawater and acidic chloride attack.
02
Strength Without Aging
Solid-solution hardening removes precipitation treatment from the plate route entirely.
03
High-Temperature Oxidation Resistance
Sheet and plate keep their properties toward 980 °C for ducting, liners, and heat shields.
04
Weld Overlay and Cladding Base
The grade serves as cladding and liner material on carbon and low-alloy steel vessels.
05
Clean Formability
Cold-rolled sheet bends, rolls, and draws without intermediate annealing in most fabrication sequences.
06
Cut-to-Size Delivery
Blanks, circles, and profile-cut parts ship to drawing, cutting scrap and freight weight on site.
07
WHY CHOOSE US
Why Choose Inconel 625
Ordering flat product through Southerly Alloy puts the thickness, condition, and cut plan through one review before we issue the quotation. In addition, the rolling route follows the ordered thickness, and every plate carries heat-number documentation back to the melting plant.
01
Thickness-Led Routing
Hot-rolled, cold-rolled, and strip routes follow the ordered thickness rather than what happens to be in stock.
02
Mill-Linked Traceability
Chemistry, mechanicals, and heat numbers follow the plate from melting through finishing.
03
Cutting and Edge Control
Plasma, laser, waterjet, or shear cutting with the edge condition written into the order.
04
Export Packing for Flat Product
Wooden cases, edge protection, and moisture barriers prepared for sea freight.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
Flat product follows the thickness: the mill hot rolls plate and cold rolls sheet and strip. Then, inspection follows each stage, and the delivered condition matches the ordered grade with full heat traceability.
01
Melt and Refine
The melt shop controls charge chemistry to the UNS N06625 window, with refining selected to the specification and end use.
02
Ingot Breakdown
The mill forges or rolls ingots to slab and transfer bar for the flat-product route.
03
Hot Rolling
Slabs pass through hot rolling to plate thickness with controlled finishing temperature and reduction.
04
Cold Rolling
Sheet and strip pass through cold reduction to final gauge with intermediate anneals between passes.
05
Heat Treatment
Grade 1 annealing and Grade 2 solution annealing run to the temperature minimums of the ordered condition.
06
Pickling and Descaling
Pickling removes scale to the specified finish, and the team inspects surfaces before cutting.
07
Cutting and Leveling
Plates and coils leave this stage cut, leveled, and edge-finished to the ordered sizes and tolerances.
08
Final Testing
The lab completes chemistry, tensile, hardness, and ultrasonic or dimensional checks before documentation goes out.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
The chemistry window below applies to ASTM B443 flat product for UNS N06625. However, the governing purchase specification takes precedence for acceptance.
| Element | Content |
|---|---|
| Nickel (Ni) | Balance |
| Chromium (Cr) | 20.0–23.0% |
| Molybdenum (Mo) | 8.0–10.0% |
| Niobium + Tantalum (Nb + Ta) | 3.15–4.15% |
| Iron (Fe) | 5.00% max. |
| Cobalt (Co) | 1.00% max. |
| Carbon (C) | 0.10% max. |
| Manganese (Mn) | 0.50% max. |
| Silicon (Si) | 0.50% max. |
| Phosphorus (P) | 0.015% max. |
| Sulfur (S) | 0.015% max. |
| Aluminum (Al) | 0.40% max. |
| Titanium (Ti) | 0.40% max. |
Mechanical Properties
The rolling route and grade set the minimum room-temperature values. First, Grade 1 ships annealed at 871 °C (1600 °F) minimum. By contrast, Grade 2 ships solution annealed at 1093 °C (2000 °F) minimum for creep-limited duty.
| Product Form | Standard | Condition / Grade | Tensile Strength | Yield Strength, 0.2% Offset | Elongation |
|---|---|---|---|---|---|
| Cold-rolled sheet and strip | ASTM B443 | Grade 1 | ≥827 MPa (120 ksi) | ≥414 MPa (60 ksi) | ≥30% |
| Hot-rolled sheet and hot-rolled plate up to 70 mm | ASTM B443 | Grade 1 | ≥758 MPa (110 ksi) | ≥379 MPa (55 ksi) | ≥30% |
| Cold-rolled plate up to 9.5 mm | ASTM B443 | Grade 1 | ≥758 MPa (110 ksi) | ≥379 MPa (55 ksi) | ≥30% |
| Plate, sheet, and strip, all sizes | ASTM B443 | Grade 2 | ≥690 MPa (100 ksi) | ≥276 MPa (40 ksi) | ≥30% |
Grade 2 carries lower room-temperature minimums because the higher solution-annealing temperature coarsens the grain in exchange for creep resistance. Also, we supply plate over 70 mm to mechanical properties agreed at the time of order.

Select the Route
Hot-rolled plate, cold-rolled plate, sheet, or strip to ASTM B443, with ASME SB443 where code applies.
3
Confirm the Grade
Grade 1 for strength-led duty, Grade 2 for creep-limited service above about 593 °C.
4
Agree the Cut Plan
You fix plate sizes, blanks, circles, and edge condition, so the quotation captures cutting scrap before pricing.

FAQ
Frequently Asked Questions
Which ASTM specification covers Inconel 625 plate and sheet?
ASTM B443 covers hot-rolled and cold-rolled plate, sheet, and strip, with ASTM B906 supplying the general requirements for flat-rolled product. In addition, ASME SB443 applies under pressure-code jurisdiction.
What thickness counts as plate rather than sheet?
Hot-rolled plate starts at 3/16 in. (4.8 mm), and cold-rolled plate runs from 4.8 mm to 9.5 mm. In addition, sheet spans 0.46 mm to 6.4 mm, and strip runs from 0.13 mm to 6.4 mm in the cold-rolled condition.
When should Grade 2 Inconel 625 plate be specified?
Specify Grade 2 for creep-limited service above about 593 °C; the condition ships solution annealed at 1093 °C (2000 °F) minimum. By contrast, Grade 1 covers strength-led duty at lower temperatures with higher room-temperature minimums.
Is Inconel 625 plate suitable for sour service?
Yes. The grade chemistry supports NACE MR0175 / ISO 15156 qualification. As a result, sour-service orders receive chemistry, hardness, and traceability records compiled for review.
Can Inconel 625 sheet be welded and formed?
Yes. Sheet and plate weld with ERNiCrMo-3 filler without preheat, and the grade generally needs no post-weld heat treatment. In addition, cold-rolled sheet forms and bends without intermediate annealing in most sequences.
How is Inconel 625 plate priced?
Inconel 625 plate and sheet is typically priced by weight (kg). In addition, the final price depends on the nickel surcharge, dimensions, rolling route, cutting scope, quantity, and required delivery terms. The applicable Incoterm is stated on every quotation.
What is your MOQ for Inconel 625 plate?
Single-plate orders are available for stocked thickness and width combinations.
What are your trade terms for Inconel 625 plate?
We quote FOB as standard, with EXW, CIF, and DAP available against confirmed destinations.
What is the lead time for Inconel 625 plate and sheet?
Stocked gauges ship in 7-15 days. However, the mill schedules production plates against rolling availability.
Do you provide EN 10204 3.1 or 3.2 certificates?
Yes — 3.1 mill test certificates are standard on every delivery. Moreover, we can arrange 3.2 certification with third-party endorsement on request.
REQUEST FOR QUOTATION
Need A Custom Alloy Solution?
Send the thickness, width, length, grade condition, and cut plan. In return, the quotation comes back with rolling route, testing scope, documentation, Incoterm, and lead time. Additionally, you can attach fabrication details such as forming or welding sequence for engineering review.
