Titanium Grade 3 Stud Bolts manufactured at TorqBolt are of Excellent stiffness,toughness and high strength low density combination.
Dimensional standards as per ASME B18.2.1,DIN 976,DIN 938,DIN 939,DIN 2510,BS 4439,BS 2693,BS4882 are provided.
The raw material of these fasteners is classified as AeroSpace Titanium Alloys. Being a PED certified Fasteners Manufacturer by TUV Rheinland,our fasteners are accompanied with EN 10204 3.1/3.2 certification. Titanium Grade 3 Stud Bolts are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.
Titanium Grade 3 Is Unalloyed Titanium With Medium Oxygen. Grade 3 Has Better Strength As Compared To Grade 2.we Offer Heavy Hex Bolt As Per Asme B18.2.1, B18.2.3.6m, Heavy Hex Nut As Per Asme B18.2.2 & B18.2.4, Flange Studs As Per Asme B16.5 For High Pressure, High Temperature Requirement.
Titanium Grade 3 Stud bolts are externally threaded fasteners with an integral head, manufactured per ASME B18.2.1, ISO 4014/4017, and DIN 933/931. TorqBolt produces Titanium Grade 3 Stud bolts in metric (M6–M100) and imperial (1/4"–4") diameters with custom lengths from 10 mm up to 3000 mm.
Head Styles Available
Hex head — ASME B18.2.1, the workhorse for general bolting
Heavy hex head — thicker head for high-load joints, ASTM A325 / A490 patterns
Socket head cap (SHCS) — ASME B18.3 / DIN 912, ideal where space is limited
Titanium Grade 3 Stud bolts are supplied with full or partial threading. Full-thread (UNC, UNF, ISO metric coarse/fine) for tension-only joints; partial-thread shank for shear loads where the unthreaded grip carries the load. Thread fits per ASME B1.1 (Class 2A) or ISO 965 (6g) by default; tighter Class 3A / 4h6h fits available on request. Engagement length follows the 1.5×D rule for tapped holes; 1.0×D minimum on through-bolting.
Mechanical Performance
Titanium Grade 3 Stud bolts achieve characteristic tensile strength, yield, and elongation per the source-material spec, with proof-load testing and hardness verification per ASTM F606 / ISO 898-1. Torque-tension calibration is published per ASME PCC-1 for critical joints. Each lot ships with EN 10204 3.1 (or 3.2 on request) certificates listing chemistry, mechanicals, hardness, and dimensional inspection.
Custom Configurations
TorqBolt can produce Titanium Grade 3 Stud bolts to drawing, with non-standard heads, drilled-shank variants, double-end, captive, or matched-set configurations. Coatings include zinc, PTFE, Xylan, hot-dip galvanized, and electroless nickel. NACE MR0175 / ISO 15156 sour-service certification on request.
Titanium & Titanium Alloys
Titanium alloys deliver an exceptional strength-to-weight ratio (density ~4.5 g/cm³, half of steel) combined with outstanding seawater + chloride corrosion resistance — the spontaneously-formed TiO₂ surface film is impervious to chlorides and most oxidizing acids. Titanium is the default for marine offshore, desalination, chemical-process, and aerospace fasteners requiring weight reduction with corrosion immunity.
Grade 2 commercially-pure (CP-Ti) is the workhorse: yield ~275 MPa, fully formable, weldable, the standard for heat-exchanger tubing and chloride-service bolting. Grade 5 (Ti-6Al-4V) is the alpha-beta alloy delivering yield ~828 MPa after solution + age treatment per AMS 4928 / ASTM B348 — the dominant aerospace + medical grade. Grade 7 / Grade 11 add Pd for crevice + reducing-acid resistance. Grade 9 (Ti-3Al-2.5V) is the high-strength tubing alloy. Grade 12 (Ti-Mo-Ni) trades strength for hot-brine corrosion performance.
Titanium fasteners ship per ASTM B348 (Grade 2 / 5) and AMS 4928 / 4965 with EN 10204 3.1 / 3.2 certificates including hydrogen (≤ 125 ppm), oxygen, and tensile testing. Welding requires inert-gas shielding (back-purged Ar) to prevent embrittlement. NACE MR0175 sour-service is fully qualified across all common grades.
