Gr5 Annealed Titanium Alloy Bar ASTM B348 5-150mm

Gr5 Annealed Titanium Alloy Bar ASTM B348 5-150mm

This bar is rolled or forged in Gr5, the Ti-6Al-4V alloy, then annealed to remove the internal stress left by hot working. Annealing is what makes the difference on the shop floor: the bar machines without chipping, drills without work hardening at the hole edge, and holds a straightness that survives turning down to size. Diameter runs from 5mm to 150mm and bars are cut to 500, 1000, 3000 or 6000mm as ordered.

Annealed Condition and What It Gives

After annealing the structure is equiaxed alpha plus beta, which balances strength against ductility and gives a predictable response to machining. The alloy keeps its mechanical properties in low and ultra low temperature service when the interstitial content is kept low, and it remains non magnetic in strong fields, so the bar is used where a magnetisable steel part would interfere with instruments. Service temperature for the alloy reaches 450 to 500 C, well above what aluminium alloys can take.

Bar Specification

Grades We Roll

Alongside Gr5, the same line supplies Gr1, Gr2, Gr3, Gr4, Gr6, Gr7, Gr9, Gr11, Gr12 and Gr23, plus the Russian designations BT1-00, BT1-0, BT1-2, BT4-0, BT4-1, BT4, BT5-1, BT6, BT6C, BT3-1, BT8, BT9, BT14, BT20 and BT22, and Ti15333. Matching the grade to the medium avoids paying for alloying elements the part does not need.

Ultrasonic Testing and Certification

Bars can be ultrasonic tested to expose internal voids, inclusions and centre porosity that a visual check will never show, which matters when the bar is destined for a pressure retaining or dynamically loaded part. Each shipment carries an EN10204 3.1 certificate that ties the heat number to the chemical and mechanical results, and a third party inspection can be arranged before dispatch.

Where the Bar Goes

Typical uses are machined shafts, valve stems, pump components, fasteners, medical implant blanks and engine or structural parts where the strength to weight ratio counts. Titanium also resists chlorides, sulphuric and nitric acid and stress corrosion, so chemical and marine hardware made from the bar lasts where stainless steel pits.
