Titanium Grade 7 Forgings
Metracore Alloys supplies and manufactures high-quality titanium grade 7 forgings to industries where hot hydrochloric acid, wet chlorine, and concentrated brine destroy most engineering metals within a few years.
As a premier manufacturer, we produce Grade 7 Titanium Forgings engineered to pass rigorous testing for corrosion resistance, strength, and dimensional accuracy. Titanium Grade 7 (UNS R52400) is commercially pure titanium carrying a 0.12-0.25% palladium addition, the source of its resistance to reducing acids and crevice attack. Furthermore, the alloy offers an exceptional strength-to-weight ratio, superior weldability, and extended operational durability. Forged rings, discs, shafts and custom shapes are supplied to ASTM B381 Grade 7 and ASME SB381, machined precisely to customer drawings. Supported by rigorous quality assurance and full material traceability, we supply custom and standard forged components to meet exact project demands worldwide.
What are Titanium Grade 7 Forgings?
Titanium Grade 7 Forgings are components shaped under compressive force from palladium-bearing commercially pure titanium, then machined to the required size. Forging refines the billet’s grain structure, leaving a denser part that outlasts castings under cyclic fatigue.
Grade 7’s chemistry matches Grade 2 except for palladium, which shifts the corrosion potential so the oxide film self-repairs in reducing conditions. CP Titanium Grade 7 Forgings therefore withstand three acids in particular: hydrochloric, sulphuric and phosphoric. Crevice resistance in chlorides improves too. High strength-to-weight, outstanding weldability and long-term reliability round out the case.

Key Features
Eight characteristics make Grade 7 a default choice for severe chemical duty. Corrosion behaviour leads the list.
- Corrosion resistance stretches from oxidising chlorides into reducing media, where palladium keeps the oxide film repairing itself.
- Reducing acid resistance. Hydrochloric and sulphuric acids attack unalloyed titanium; Grade 7 tolerates both across much wider concentration bands.
- A 4.51 g/cm³ density gives strength-to-weight well beyond steel.
- Fatigue resistance. Grain flow follows the forged contour, so cyclic loads meet fewer crack initiation sites.
- Welding asks for nothing beyond standard TIG practice and matching filler wire.
- Low maintenance. Components run for years without recoating, lining or inhibitor dosing.
- Decades of operational life offset the higher price.
- Harsh chemical environments. Wet chlorine, hot brine, mixed acid streams: all sit inside the service envelope.
Manufacturing Standards & Quality Control
Processing Grade 7 differs from other CP titanium in two respects: palladium must stay homogeneous through melting, and forging temperatures sit below the beta transus, about 915°C, to preserve fine alpha grain. Our source mills control both variables. Their ASTM B381 Grade 7 Forgings carry EN 10204 3.1 certification, with ASTM B348, ASTM B265 and ASME SB381 covering related supply. Inspection spans Ultrasonic Testing (UT), PMI Testing, mechanical testing, chemical analysis, dimensional inspection and visual inspection.
Advantages of Titanium Grade 7 Forgings
Specifying forged Grade 7 brings 6 practical advantages, most tied to lifetime cost rather than purchase price.
- Corrosion resistance surpasses Grade 2 titanium in reducing environments.
- One material covers oxidising and reducing media alike, even when process chemistry shifts.
- Light components still deliver full mechanical strength.
- Equipment life extends well past coated alternatives because the passive film repairs itself.
- Maintenance costs drop once linings and coatings disappear from the schedule.
- Aggressive process conditions don’t force early derating or replacement.
