HEBEI ALL TRUST STEEL CO., LTD manufactures premium en 10216-5 1.4541 tube utilizing virgin-grade X6CrNiTi18-10 stainless steel, engineered specifically for pressure-critical systems operating continuously between 400°C and 800°C. Our manufacturing capacity is above 15,000 tons per year and we have 100% hydraulic testing. Our seamless tubes are provided with titanium stabilisation technology to exclude the possibility of intergranular corrosion in welded assemblies. Every batch is 100% eddy current scanned and intergranular corrosion validated to EN ISO 3651-2. Full heat number traceability is available, with full EN 10204 3.1 Mill Test Certificates, for aerospace, petrochemical and power generation applications.

The product is the benchmark solution in Europe for pressure-purpose applications requiring extreme heat stability. This titanium stabilised material has strategic metallurgical engineering that bonds carbon elements at the molecular scale, as opposed to ordinary austenitic grades.
This particular tube grade addresses a major industrial problem: the precipitation of chromium carbide in heat affected zones. Standard materials of 304 grade develop sensitisation when subjected to lengthy periods of time at high temperatures of 427°C to 816°C. With our 1.4541 formulation we have completely eliminated this deterioration by regulated titanium addition.
Manufacturing follows strict EN 10216-5 protocols using solid-billet hot extrusion technology. Each tube begins with spectrographically verified raw material containing 17.0-19.0% chromium, 9.0-12.0% nickel, and stabilizing titanium content between five times the carbon percentage up to 0.70%.
Solution annealing is done at tightly regulated temperatures, and a specific stabilisation heat treatment is used. This two-stage thermal treatment leads to a uniform austenitic matrix with full dissolution of carbides, which ensures a predictable mechanical behaviour during pressure cycling.

Titanium Stabilization Technology
Our product incorporates titanium at precisely calculated ratios, forming stable titanium carbides instead of damaging chromium carbides. This metallurgical intervention provides absolute immunity to intergranular attack during continuous exposure in the 400-800°C operational window, where conventional grades fail catastrophically.
Rigorous Multi-Stage Testing Protocol
Every production lot passes through vertical atmosphere annealing chambers, followed by mandatory high-pressure hydrostatic testing to verify leak-proof integrity. Mechanical validation includes destructive flattening tests, flaring expansion tests, and elevated-temperature tensile characterization—ensuring your critical infrastructure meets the most demanding safety margins.
Flexible Dimensional Customization
We solve specific technical needs with precise cold-working capabilities tolerances up to ±0.05 mm. Our state-of-the-art equipment provides accurate specifications for bespoke bevelled ends for orbital welding, precise cut lengths up to 12 metres for skid mounted assemblies and internal counterboring for optimised fluid dynamics.
Comprehensive Traceability Documentation
Each shipment includes complete EN 10204 3.1 Mill Test Certificates with verified chemical composition analysis, mechanical property test results, and mandatory intergranular corrosion validation reports conforming to EN ISO 3651-2 Method A protocols—providing full audit-trail compliance for your quality management systems.

Aerospace Exhaust Systems
Aircraft engine exhaust manifolds and bellows assemblies demand materials that withstand extreme thermal cycling and vibration-induced fatigue. The en 10216-5 1.4541 tube maintains structural ductility and corrosion resistance against aggressive exhaust gas compositions at temperatures exceeding 650°C.
Power Generation Boiler Tubes
Superheater tubes and high-pressure steam lines in utility-scale power plants require PED 2014/68/EU compliance and resistance to steam-side oxidation. Our titanium-stabilized tubes deliver extended service life in high-pressure environments without creep deformation or oxide scale spallation.
Petrochemical Thermal Processing
Heat exchangers handling organic acids, nitric acid reactors, and thermal cracking units benefit from the tube's resistance to localized corrosion and stress corrosion cracking. The stabilized microstructure prevents sensitization in welded connections exposed to cyclic thermal stresses.
Chemical Processing Equipment
This grade is used for high temperature reactor vessels , distillation column internals and catalytic converter housings . A combination of high temperature strength retention and resistance to inter granular attack in the corrosive process environment is required .

HEBEI ALL TRUST STEEL has been in the stainless steel tube production for over 15 years, and has strategic cooperation with over 15 steel mills with certificate, which guaranties the stability of the supply chain and the quality of the materials. Our continuous stockpile of 5,000 tons of austenitic grades allows us to respond quickly to immediate project needs.
We support mixed container loading with complementary products including pipe fittings, flanges, and valves—reducing your logistics complexity. Our professional engineering team provides material selection guidance, corrosion resistance analysis, and CAD drawing verification to optimize your system design.
Every tube undergoes 100% non-destructive testing using automated eddy current scanning systems and laser dimensional profiling. Third party SGS, TÜV or Bureau Veritas inspections may be undertaken on your request with full paperwork supplied for international customs clearance.
Our export packing is one protective sleeve, hexagonal bundle with waterproof covering, and fumigation free hardwood case – avoiding surface damage, moisture penetration and salt corrosion during ocean freight. We ship via Shanghai/Ningbo/Tianjin/Qingdao port, flexible to FOB/CFR/CIF/DDP term.
