Seamless elbows 1.4571 / 316Ti
What are seamless elbows 1.4571 / 316Ti?
Seamless elbows 1.4571 / 316Ti are stainless steel pipe fittings manufactured without a welded seam. They are used to change the direction of piping systems (typically 45° or 90°). The base material — stainless steel grade 1.4571 (also known as AISI 316Ti or DIN X6CrNiMoTi17‑12‑2) — is an austenitic, titanium‑stabilised, acid‑resistant steel that combines good general corrosion resistance with improved resistance to intergranular corrosion after welding.
Material and standards
This category covers fittings made from titanium‑stabilised 316 stainless steel. Common technical designations you may see:
- EN: 1.4571
- AISI/ASTM (USA): 316Ti
- DIN: X6CrNiMoTi17‑12‑2
- Often referenced in Polish/European trade as H17N13M2T / H18N10MT
Use of these synonyms in product search (316Ti elbows, 1.4571 pipe fittings, stainless steel elbow) helps find compatible items quickly.
Where and how these seamless elbows are used
Seamless 316Ti elbows are suitable for a wide range of applications because of their corrosion resistance and weldability. Typical uses include:
- Chemical and petrochemical installations — piping that conveys corrosive media
- Food, beverage and pharmaceutical processing — sanitary and process lines
- Medical equipment and device components — non‑implant surgical instruments and equipment housings
- Paint and coatings industry — equipment parts exposed to solvents and acids
- Marine and offshore piping — where resistance to seawater corrosion is required
- HVAC, plumbing and general building services
- Automotive and small workshop fabrications — where corrosion resistance and formability matter
Benefits of 316Ti and seamless construction
- Improved welding performance: Titanium stabilisation reduces the risk of intergranular corrosion after welding compared with unstabilised grades.
- Corrosion resistance: Good resistance to many acids, chloride‑containing environments and general corrosive media common in industrial processes.
- Smoother internal surface: Seamless elbows have no longitudinal weld seam, reducing turbulence, deposits and local corrosion sites.
- Formability and strength: Austenitic structure gives good ductility and toughness over a wide temperature range.
Fabrication, welding and maintenance notes
Seamless 316Ti pipe fittings are widely weldable using standard techniques. Because the titanium stabiliser prevents carbide precipitation, preheating is usually not required and post‑weld heat treatment is generally unnecessary for most service conditions. As with all stainless steels, regular cleaning and appropriate passivation (or pickling where required) will help maintain corrosion performance. Note: like other austenitic stainless steels, 316Ti can be susceptible to chloride stress‑corrosion cracking under certain conditions — material selection and system design should consider operating temperature, chloride exposure and mechanical stress.
Who should consider these pipe fittings?
These elbows are suitable for purchasers ranging from DIY and workshop users to contractors, OEMs and engineering firms in sectors such as chemical processing, food & beverage, pharmaceuticals, marine/offshore and building services. If you require a corrosion‑resistant, weldable elbow with a smooth internal profile, seamless 1.4571 / 316Ti fittings are a common choice.
