Titanium Grade 2 Stud Bolts

ASME B18.31.2ASTM B348

Titanium Grade 2 stud bolts bring low mass, corrosion resistance and commercially pure titanium formability to flange and cover joints. The stud condition, mating nuts and end form determine how the assembly carries and retains clamp load.

Heat Treatment

Annealed

Annealing reduces working stresses and restores ductility, with atmosphere and surface control limiting contamination during heating.

What we can make in Titanium Grade 2

Fully threaded

Two nuts clamp the flange or cover; usable thread length spans the assembled grip.

Double-end

A plain centre spans the grip, with a threaded portion at each end for the nuts.

tap endnut end

Tap-end

One end engages a tapped casing; the exposed end accepts the cover nut.

Thread size and fit; overall and effective thread length; end geometry; lot identification.

Manufacturing route

CNC machining suits samples and special end forms. Repeat lots use cut-to-length stock with rolling or cutting selected for the ordered thread and material condition.

Heat treatment & final condition

Forming and thermal processing require contamination control. The final surface is cleaned before dimensional and material acceptance.

Finished geometry

End lengths, runout and effective thread engagement are checked separately from overall length; tap ends are gauged to their own fit requirement.

Where Titanium Grade 2 fits — and what matters

Silver distillation columns with access ladders and yellow service platforms

Chemical Processing

Chemical pump covers and reactor connections

Titanium Grade 2 stud bolts & threaded rods clamp chemical pump covers and reactor connections with nuts on the exposed ends, keeping the stud in place when a cover is removed. Process liquid can remain at the contact after the exposed surface drains.

Pumps, Valves & OEM

Pump casings and valve bonnets

Titanium Grade 2 stud bolts & threaded rods clamp pump casings and valve bonnets with nuts on the exposed ends, keeping the stud in place when a cover is removed. Repeated maintenance makes fit, engagement and access part of the component specification.

Mining & Mineral Processing

Chemical-recovery pump and vessel covers

Titanium Grade 2 stud bolts & threaded rods clamp chemical-recovery pump and vessel covers with nuts on the exposed ends, keeping the stud in place when a cover is removed. Leach solution and deposits act on the installed part; corrosion duty is separate from abrasive wear.

Titanium Grade 2 material data
UNS N10276

Hastelloy C-276

Resistance to chemically aggressive, mixed process streams.

Connection priority
Stud tension and clamp-load retention
Process liquid and shutdown chemistry
C-276 is selected for its nickel–chromium–molybdenum–tungsten chemistry. Residual product, cleaning liquid and oxidising contamination can expose a sheltered connection differently from the main flow. Include liquid retained at the exposed thread roots and nut-bearing faces in the exposure description.

UNS N06625

Inconel 625

Solid-solution strength and resistance to aggressive process liquids.

Connection priority
Stud tension and clamp-load retention
Annealed or solution-annealed 625
The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at the exposed thread roots and nut-bearing faces in the exposure description.

UNS N06022

Hastelloy C-22

Corrosion resistance across oxidising and reducing process exposures.

Connection priority
Stud tension and clamp-load retention
Production and cleaning cycles
C-22’s chromium-bearing chemistry is relevant when chemical exposure changes between operating and cleaning cycles. Include both liquids when comparing it with C-276 or a B-type nickel alloy. Include liquid retained at the exposed thread roots and nut-bearing faces in the exposure description.

Questions about Titanium Grade 2 stud bolts & threaded rods

Does changing the stud alloy also change the nut selection?

The nut needs compatible internal threads, sufficient engaged height and a specified material condition. Select lubricant or surface treatment with the stud–nut pair, because assembly friction affects the preload obtained from tightening.
