Tantalum Studs - High-Performance Fasteners for Extreme Chemical Environments
XI AN LINHUI IMPORT AND EXPORT Co., LTD. operates two modern factories with 30 titanium metal production lines, bringing 21 years of manufacturing excellence to every Tantalum Studs order. Our system quality meets ISO/SGS/TUV standards, ensuring each fastener delivers unmatched reliability. With an annual production capacity of 800 tons and flexible delivery via DHL, FEDEX, air freight, or sea freight, we supply critical industries worldwide.
The products feature a density of 16.69 g/cm³ and form a self-healing Ta₂O₅ passive layer that resists chemical attack below 150°C. Available in R05200 (99.95% pure) and R05252 (Ta-2.5%W) grades, these fasteners meet ASTM B365 and ASTM F560 standards for demanding applications.
Key Features & Benefits
Superior corrosion immunity in hot hydrochloric, sulfuric, and nitric acids where stainless steel fails within hours. The R05252 grade increases tensile strength by 30-50% while maintaining chemical stability.
High-temperature vacuum stability and a thermal expansion coefficient (6.3 µm/m·K) matching glass make these studs ideal for glass-lined reactor seals. Zero outgassing ensures contamination-free semiconductor processing.
Medical-grade biocompatibility (ASTM F560) promotes direct bone ingrowth in orthopedic implants, reducing rejection risk compared to alternative materials.

Why Choose Us?
Coordinate process supply kills go betweens, conveying production line estimating without compromising quality control. Our 200+ ton stock stock empowers 3-7 day conveyance on standard items.
Flexible MOQ bolsters trial orders from 100 kg, whereas our multilingual building group gives fabric determination interview in English, Chinese, Spanish, and Arabic.
Third-party review by SGS, BV, TÜV, DNV, and ABS is accessible upon ask. Each item incorporates total MTC documentation for full traceability.
Manufacturing Process
We utilize electron pillar vacuum circular segment casting for R05200 to maximize virtue and ductility. R05252 amalgams experience powder metallurgy handling to accomplish uniform tungsten distribution.
Rolled strings avoid the cold welding issues common with cut strings in delicate headstrong metals. Each string profile experiences Go/No-Go gage testing to guarantee exactness fit.
Applications
Chemical Processing: Securing glass-lined reactor internals and tantalum-cladding repair packs where Sort 316 stainless erodes immediately in bubbling hydrochloric corrosive environments.
Medical Implants: Bone obsession and hip/knee substitution equipment utilizing ASTM F560 review fabric for osseointegration and decreased push protecting in complex reconstructive surgeries.
Semiconductor Manufacturing: High-temperature vacuum heater installations and sputtering target congregations requiring zero defilement amid ultra-pure lean film statement processes.
Packaging & Shipping
Individual poly packs secure strings from harm amid travel. Wooden cases with froth embeds avoid development for worldwide sea freight.
Expedited shipping through DHL/FEDEX comes to you inside 5-7 days. Discuss cargo and ocean cargo choices oblige bigger volume orders with competitive rates.
Export Markets
Our Tantalum Studs reach 60+ countries across North America, Europe, the Middle East, and Southeast Asia. Long-term partnerships with CEFC, PTT, PETRONAS, and LUKOIL demonstrate our reliability in mission-critical applications.
Compliance with PED 2014/68/EU, FDA standards, and NORSOK M-650 ensures your projects meet regional regulatory requirements without delays.
Quality Inspection
GDMS/ICP analysis verifies purity and monitors interstitial oxygen content to prevent embrittlement. ASTM E112 microstructure examination confirms uniform recrystallized grain structure.
Dye penetrant inspection detects surface laps or cracks that could initiate corrosion. Mechanical testing validates tensile and yield strength compliance with ASTM B365 requirements.
Full traceability via heat number documentation and EN 10204 3.1/3.2 certificates accompany every shipment.
FAQ
Q: Can these studs withstand hydrofluoric acid?
A: No. Never utilize in HF, acidic fluorides, or oleum situations as quick disintegration occurs.
Q: Why do strings rankle amid installation?
A: Tantalum's delicateness causes cold welding beneath contact. Apply molybdenum disulfide oil and utilize rolled strings to anticipate seizure.
Q: What's the most extreme temperature in air?
A: Constrain to 250-300°C. Over this, oxygen dissemination causes brittleness. High-temp utilize requires vacuum or idle gas protection.
Q: How does R05252 vary from R05200?
A: R05252 includes 2.5% tungsten for 30% higher ductile quality whereas keeping up erosion resistance beneath mechanical loads.
