What pickling means
Hot rolled titanium plate comes off the mill with oxide scale. Dark grey. Hard. The scale is not good for machining. It wears out tools. It hides surface defects.
Pickling removes the scale. Acid bath. The plate comes out clean. Bright. Silver. Oxide-free.
Pickled titanium plate for industrial machining is ready for your saw, mill, or lathe. No scale to fight through. No surprises under the surface.
Why pickled for machining
As-rolled plate has scale. The scale is hard. Harder than titanium itself. You cut through it. Your tool wears faster. Edges chip.
With pickled plate, you start with clean metal. Consistent hardness. No hard spots. No embedded scale.
For pickled titanium plate for industrial machining, the pickling step saves you time and tool cost.
Which grade for machining
| Grade | Material | Tensile | Machinability |
| Grade 2 | Pure titanium | 345 MPa | Good. Soft. Gummy. |
| Grade 5 | Ti-6Al-4V | 895 MPa | Fair. Harder. Requires sharp tools. |
Grade 2 is easier to machine. Softer. Good for general machining.
Grade 5 is stronger. Used for structural parts. Harder on tools.
Both grades available pickled. Scale removed.
Material specs (Grade 2)
| Property | Value |
| Standard | ASTM B265 |
| Tensile (min) | 345 MPa |
| Yield (min) | 275 MPa |
| Elongation | ≥ 20% |
| Density | 4.51 g/cm³ |
| Hardness | ~160 HB |
Specs (Grade 5)
| Property | Value |
| Tensile (min) | 895 MPa |
| Yield (min) | 828 MPa |

Common thicknesses for machining
| Thickness (mm) | Typical machined part |
| 3 – 5 | Flanges, brackets, small parts |
| 6 – 10 | Valve bodies, pump components |
| 12 – 16 | Heat exchanger tube sheets |
| 18 – 25 | Reactor components, structural parts |
| 25 – 30 | Heavy flanges, thick brackets |
Plate is saw cut into blanks. Then machined to final shape.
Where pickled plate goes
Machine shops. They receive pickled titanium plate for industrial machining. Cut it on a band saw. Clamp it on a milling machine. Drill holes. Tap threads. Turn parts on a lathe.
Parts come out of these plates:
-
Flanges. For piping. Bolted connections. Machined from 10mm to 30mm plate.
-
Tube sheets. For heat exchangers. Hundreds of holes drilled. Pickled plate ensures consistent drilling.
-
Valve bodies. Machined from thick plate. 20mm to 30mm. Complex shapes.
-
Pump components. Housings. Mounting brackets. Machined from 6mm to 20mm.
-
Custom brackets. Any shape. Machined from plate.
For pickled titanium plate for industrial machining, the clean surface means no scale to interrupt the cut.
Pickled vs polished vs as-rolled
| Surface | Appearance | Best for |
| As-rolled | Dark grey with scale | Structural only, no machining |
| Pickled | Bright silver, matte | General machining |
| Polished | Bright, reflective | Cosmetic, high finish |
Pickled is the standard for machine shops. Clean. No scale. Not slippery like polished.
What the pickling process removes
Mill scale. Iron contamination from rolling. Embedded oxides. Surface impurities.
Pickling leaves a clean titanium surface. The natural oxide layer remains. That's good. It protects against corrosion.
For pickled titanium plate for industrial machining, the surface is ready for layout. Scribe lines show up. No scale flakes.
Machining tips for pickled titanium
Titanium is not steel. Adjust your parameters.
Use carbide tools. Sharp edges. Low surface speed. High feed. Flood coolant.
Grade 2 is gummy. Uses sharp tools. Don't let the tool rub.
Grade 5 is harder. Uses slower speeds. More rigid setup.
Drilling. Short pecks. Clear chips often. Use coolant through the tool if possible.
Tapping. Use form taps. Or thread mill. Cutting taps work but break easily.
For pickled titanium plate for industrial machining, the pickled surface reduces tool wear. No scale to break through.
Saw cutting
Plate is often saw cut first. Horizontal band saw. Carbide tipped blade. Variable speed. Slow feed.
Pickled plate saw cuts cleaner than as-rolled. No scale to dull the blade.
Why not as-rolled
As-rolled plate has scale. Scale is hard. It also hides cracks. You don't see a surface flaw until you machine. Then you find out the plate had a defect.
Pickled plate shows everything. Surface defects are visible. You can reject bad plate before machining.
For pickled titanium plate for industrial machining, you know what you're getting. No surprises.
Storage and handling
Pickled plate has a clean surface. Fingerprints show. Protect from oil and dirt.
Store indoors. Dry area. Keep paper between plates if stacking.
The oxide layer will regrow naturally. Pickling doesn't change the metal's corrosion resistance.
Traceability
Mill test reports. Heat number traceable. ASTM B265 cert.
EN 10204 3.1 standard. 3.2 available.
FAQ
Q: Grade 2 or Grade 5 for my part?
A: Grade 2 for general corrosion resistance and easier machining. Grade 5 for high strength. Tell us your application.
Q: Pickled or polished for machining?
A: Pickled. Polished is too slippery. Clamps may slip. Pickled has a matte finish.
Q: Can you cut to my blank size?
A: Yes. Send your cut list. We saw cut. Deburr. Pack. No extra charge under 20 pieces.
Q: Lead time?
A: Stock thicknesses 7-10 days. Non-stock 3-5 weeks.
Q: Sample plate for testing?
A: Yes. 200mm x 200mm sample. Pay shipping. Material free.
The bottom line
Machine shops need clean plate. No scale. No surprises.
Pickled titanium plate for industrial machining gives you that.
Grade 2 for general machining. Grade 5 for high strength.
Pickled. Bright. Oxide-free. Ready for your saw and mill.
For flanges. For tube sheets. For valve bodies. For custom brackets.
Clean plate means better machining. Longer tool life. Fewer rejects.
