Testing Methods For Alloy 625 Bolts
As a working Inconel 625 Bolt Supplier in India, we run every batch through these checks before dispatch.
Hardness Test
Confirms Rockwell hardness stays inside the 35 HRC sour-service ceiling
Every Batch
Spectro Chemical Analysis
Spectrometer reading checks Ni, Cr, Mo & Nb against UNS N06625 chemistry
Every Heat
Positive Material Identification
Handheld PMI analyzer confirms alloy grade on the finished bolt body
Every Order
Intergranular Corrosion Test
Confirms grain boundaries stay free of sensitization after annealing
On Request
Micro & Macro Examination
Structure check rules out cracks, laps or forging seams on studs
On Request
Proof Load Test
Verifies the bolt holds specified load without permanent set
Stud Lots
ASTM B446 Alloy 625 U Bolt Surface Finish
As-Forged Blank
Base finish before final machining and thread rolling begins
Solution Annealed & Pickled
Acid pickling clears heat scale and restores the oxide layer
Bright / Polished Finish
Smooth surface for visible flange and instrument-line joints
Dry-Film Lubricant Coat
Anti-galling coat for repeated make and break on high-torque studs
Passivated Finish
Chemical passivation reinforces the natural corrosion-resistant film

Inconel 625 Hex Bolt Vs Stud Bolt – Which To Pick?
Inconel 625 Hex Bolt
- Single-piece head & shank, quick single-wrench fit
- Best for standard, lower-pressure flange bolting
- Lower cost, shorter lead time on ready sizes
- Simple removal for routine maintenance work
Inconel Alloy 625 Stud Bolt
- Two nuts share the clamp load evenly across the joint
- Easier to reuse on repeated flange opening & closing
- Preferred for Class 900 and above high-pressure flanges
- Better fatigue life under cyclic thermal load
How To Identify A Genuine UNS N06625 Bolt Head?
Check Grade & Heat Stamp
Head or end face should carry alloy grade, heat number & maker mark
Step 1
Match PMI Reading To MTC
Ni, Cr & Mo reading on the bolt body must match certificate values
Step 2
Verify Thread Class Fit
Thread should gauge cleanly to Class 2B / 6H without forcing or slack
Step 3
Ask For Third-Party Report
SGS, BV or TUV report confirms independently witnessed test results
Step 4
