Titanium Grade 5 Round Bars, Sheets and Plates: Standards and Procurement Guide

Titanium Grade 5 Round Bars Titanium Grade 5, also known as Ti-6Al-4V or UNS R56400, is a widely used titanium alloy for demanding engineering and industrial applications. Its combination of high strength, relatively low density and corrosion resistance makes it suitable for components used in aerospace, marine, automotive and specialised industrial sectors.

For buyers and procurement teams, selecting Titanium Grade 5 involves more than specifying the alloy name. The product form, dimensions, material condition, manufacturing specification, testing requirements and documentation must all match the intended application.

This guide explains the main Titanium Grade 5 product forms, relevant material standards and important checks to complete before purchasing round bars, sheets, plates or billets.

What Is Titanium Grade 5?

Titanium Grade 5 is an alpha-beta titanium alloy commonly identified as Ti-6Al-4V. Aluminium and vanadium are its principal alloying elements.

Its recognised material designation is:

  • Material: Titanium Grade 5
  • Common name: Ti-6Al-4V
  • UNS designation: R56400
  • Material family: Alpha-beta titanium alloy
  • Common product forms: Round bars, billets, sheets, plates and forgings

The exact chemical composition and mechanical properties depend on the applicable product specification, manufacturing route, dimensions and material condition.

Buyers should always specify the governing standard rather than relying only on the commercial description “Titanium Grade 5”.

1. Titanium Grade 5 Round Bars

The final application determines the required material condition, mechanical properties, inspection level and dimensional tolerances.

Important purchasing specifications for round bars

Before ordering Titanium Grade 5 round bars, confirm:

  1. Required diameter.
  2. Required length.
  3. Quantity or total weight.
  4. Applicable material specification.
  5. Material condition.
  6. Surface finish and dimensional tolerance.
  7. Chemical and mechanical test documentation.
  8. Traceability and marking requirements.

Round bars may be supplied in different surface conditions, such as ground, machined, rough turned or other specified finishes. The required finish should be stated in the purchase enquiry.

2. Titanium Grade 5 Sheets

Titanium Grade 5 sheets are used in applications requiring thinner material sections and suitable forming or machining operations.

Potential applications include:

  • Aerospace sheet components.
  • Lightweight engineering assemblies.
  • Specialised industrial components.
  • Formed components for selected equipment.
  • Machined parts requiring thin-section starting material.

The required sheet thickness, width, length, flatness and surface condition should be specified clearly.

  • Confirm Grade 5 / UNS R56400.
  • Specify thickness and dimensional tolerances.
  • Confirm the applicable sheet specification.
  • State the required material condition.
  • Identify any surface-finish requirements.
  • Confirm inspection and test documentation.

Sheet requirements should not be assumed to be identical to plate requirements. The applicable product specification and product classification must be checked.

3. Titanium Grade 5 Plates

Titanium Grade 5 plates are used for manufacturing components where thicker starting sections are required.

Potential applications include:

  • Machined aerospace components.
  • Specialised industrial equipment.
  • Structural and mechanical components.
  • Selected pressure-equipment applications where design requirements permit.
  • Components manufactured through machining and fabrication.

Important plate procurement details

When requesting a quotation for Titanium Grade 5 plates, provide:

  • Required thickness.
  • Required width and length.
  • Quantity or weight.
  • Applicable ASTM or other project specification.
  • Material condition.
  • Surface and dimensional requirements.
  • Inspection and certification requirements.

For demanding applications, the purchase order should also specify any additional requirements for ultrasonic testing, surface inspection, traceability or other examinations where applicable.

4. Titanium Grade 5 Billets

Billets are used as starting material for selected forging and manufacturing operations.

Titanium Grade 5 billets may be required when the component manufacturing route involves forging, further machining or another approved process.

When purchasing billets, buyers should verify:

  • Grade and UNS designation.
  • Billet dimensions and weight.
  • Manufacturing route.
  • Applicable specification.
  • Material condition.
  • Required test reports.
  • Heat or lot traceability.

A billet specification should not automatically be replaced with a bar specification. The required product form must match the actual manufacturing route and purchase requirement.

5. Important ASTM Standards for Titanium Grade 5

Material standards help buyers define the required product form, chemical composition, mechanical properties and testing requirements.

Two important ASTM specifications to review are:

ASTM B348/B348M – Titanium Bars and Billets

ASTM B348/B348M covers titanium and titanium alloy bars and billets. Its scope includes Grade 5, UNS R56400.

For buyers purchasing Titanium Grade 5 round bars or billets, this is an important specification to identify in the purchase enquiry.

The standard addresses requirements such as chemical composition and mechanical testing. The applicable edition and any additional purchase requirements should be confirmed.

Official reference: ASTM B348/B348M – Titanium and Titanium Alloy Bars and Billets

ASTM B265 – Titanium Strip, Sheet and Plate

ASTM B265 covers titanium and titanium alloy strip, sheet and plate. Its listed grades include Grade 5, UNS R56400.

This specification is relevant when purchasing Titanium Grade 5 sheets and plates.

It addresses material requirements including chemical composition and applicable product testing.

Official reference: ASTM B265 – Titanium and Titanium Alloy Strip, Sheet and Plate

Important: Always confirm the current edition and exact requirements with the purchaser, supplier and project specification. A reference to ASTM B348 does not automatically cover plates or sheets, and ASTM B265 should not be used as a substitute for a bar specification.

6. AMS Specifications and Aerospace Procurement

Aerospace buyers may encounter SAE Aerospace Material Specifications (AMS) for Ti-6Al-4V products.

Examples include:

  • AMS 4911: Commonly associated with Ti-6Al-4V sheet, strip and plate requirements.
  • AMS 4928: Commonly associated with Ti-6Al-4V bars, wire, forgings and related product forms within its defined scope.

The applicable specification, revision, product form, condition and supplementary requirements must be verified against the actual purchase order.

A material described commercially as Titanium Grade 5 should not automatically be treated as compliant with an aerospace AMS requirement.

Aerospace procurement may also require approved manufacturing sources, additional inspection, process controls and traceability beyond a general industrial material purchase.

7. Titanium Grade 5 Annealed and Heat-Treated Conditions

Titanium Grade 5 is supplied in different material conditions depending on the product specification and manufacturing route.

Annealed condition

Annealed material is commonly specified for applications requiring a defined combination of mechanical properties and fabrication or machining characteristics.

ASTM B348/B348M and ASTM B265 cover annealed product requirements within their respective scopes.

Solution-treated and aged condition

Solution treatment and ageing may be specified to achieve particular mechanical properties in suitable material products.

The required condition must be stated clearly in the purchase order. Buyers should not assume that every Titanium Grade 5 bar, plate or sheet has the same mechanical properties.

Why material condition matters

Material condition can influence:

  • Tensile strength.
  • Yield strength.
  • Elongation.
  • Machining behaviour.
  • Formability.
  • Component performance.

The required properties should be checked against the relevant specification, product dimensions and material test documentation.

8. How to Check Titanium Grade 5 Material Certificates

Documentation is an important part of specialty-metal procurement.

Before accepting Titanium Grade 5 material, buyers should review the documentation required by their purchase order.

Chemical composition

The material report should identify the grade and provide the required chemical analysis.

For Grade 5, the principal alloying elements are aluminium and vanadium. Other controlled elements must also meet the applicable specification limits.

Mechanical test results

Where required by the specification, check the reported mechanical properties, including:

  • Tensile strength.
  • Yield strength.
  • Elongation.
  • Other specified mechanical tests.

The acceptance values must be compared with the exact product specification and material condition.

Heat or lot number

Material identification should allow the supplied product to be traced to its manufacturing and testing records.

Product form and dimensions

Check that the certificate and identification documents correspond to the supplied product form and dimensions.

A certificate for a different product form or material condition should not automatically be accepted.

Inspection requirements

Some projects require additional testing, such as ultrasonic examination, surface inspection or other non-destructive testing.

These requirements should be agreed before the order is placed.
