Tantalum R05200 Fasteners are fasteners manufactured from UNS R05200 unalloyed tantalum, a commercially pure tantalum grade known for excellent resistance to many aggressive chemical environments. We supply Tantalum R05200 bolts, screws, studs, nuts, washers, hex head bolts and socket head cap screws for specialized industrial applications. UNS R05200 is covered among the unalloyed tantalum grades in ASTM B365 and other tantalum material specifications.

What Are Tantalum R05200 Fasteners?

Tantalum R05200 Fasteners are specialized fastening components manufactured from UNS R05200 tantalum. R05200 is classified as unalloyed tantalum produced from electron-beam or vacuum-arc melted material. ASTM B365 specifically includes R05200 among the tantalum grades covered by its specification for rod and wire.

Tantalum is a refractory metal selected primarily for its exceptional corrosion resistance. It is particularly useful in equipment exposed to aggressive chemical media where conventional metallic fasteners may have difficulty providing the required service life.

We supply UNS R05200 Tantalum Screws and Bolts in standard and customized configurations. Depending on the application, these can include hex head bolts, socket head cap screws, stud bolts, screws, nuts and washers.

For engineered applications, the fastener dimensions, thread form, material condition, mechanical requirements and applicable product specification should always be confirmed before manufacture.

Types of Tantalum R05200 Fasteners

We supply different types of Tantalum Grade R05200 Fasteners according to the joint design and installation requirements.

➤ Tantalum R05200 Hex Head Bolts

Tantalum R05200 Hex Head Bolts have a six-sided external head that permits tightening using conventional tools. They are suitable for bolted joints in specialized chemical-processing and corrosion-intensive equipment.

➤ Tantalum R05200 Socket Head Cap Screws

Tantalum R05200 Socket Head Cap Screws have an internal hexagonal drive and compact cylindrical head. They are useful where installation space around the fastener is limited.

➤ Tantalum R05200 Stud Bolts

Stud bolts have threaded sections at both ends and are commonly used for flange connections, covers, pressure equipment and specialized machinery.

➤ Tantalum R05200 Machine Screws

Machine screws can be supplied with different head configurations and thread specifications for equipment assembly and maintenance applications.

➤ Tantalum R05200 Nuts

Matching tantalum nuts can be supplied for applications where the complete fastening assembly requires corrosion-resistant material compatibility.

➤ Tantalum R05200 Washers

Tantalum washers can be used beneath bolt heads or nuts where corrosion resistance and material compatibility are important.

➤ Custom Tantalum R05200 Fasteners

We can supply specially machined fasteners according to customer drawings, dimensions, thread specifications and application requirements.

➤ Heat Exchanger Tantalum R05200 Bolts

Are selected for specialized heat-exchanger assemblies where the process environment can be highly corrosive. Material compatibility should be evaluated based on the process fluid, temperature, pressure, joint configuration and surrounding materials.

ASTM B365 Tantalum R05200 Fasteners

ASTM B365 covers tantalum and tantalum-alloy rod and wire, including R05200, R05400, R05255, R05252 and R05240. Therefore, when the specification is referenced for a fastener, it is important to distinguish the raw-material specification from the complete fastener specification.

For Tantalum R05200 Fasteners, we can manufacture components from material meeting the required material specification and supply the fastener according to the required dimensions, threads and drawings.

DIN 17859 Tantalum Screws

DIN 17859 Tantalum Screws may be specified by customers requiring a DIN-based tantalum material reference. When purchasing such products, the exact DIN designation, product form, dimensions and material condition should be confirmed rather than assuming that a DIN reference automatically defines the complete fastener.

We review customer specifications to establish the appropriate material and manufacturing requirements before production.

Properties of Tantalum R05200 Fasteners

The major reason for selecting R05200 is its corrosion resistance rather than exceptionally high structural strength.

Key characteristics include:

  • Excellent resistance to many aggressive chemical environments
  • High melting point
  • Good ductility in commercially pure tantalum
  • Strong resistance to many acids
  • Stable protective oxide layer
  • High density
  • Good high-temperature capability
  • Suitable for specialized chemical-processing equipment

Tantalum's combination of corrosion resistance and high-temperature capability makes it useful for demanding industrial applications. Its suitability, however, depends on the exact process chemistry, temperature, mechanical loading and joint design.
