What is the EN 10216-5 Standard?
EN 10216-5:2021 is the European standard for seamless stainless steel tubes for pressure purposes, covering austenitic, creep-resistant austenitic, and duplex stainless steel tubes. Therefore, critical parameters such as material grade, test category, dimensional tolerances, and delivery condition should be explicitly confirmed during procurement.
If you are seeking seamless stainless steel tubes capable of enduring long-term high-temperature exposure, oxidation, and thermal cycling, EN 10216-5 1.4841 Stainless Steel Pipes serve as a highly reliable heat-resistant material option.
1.4841 (X15CrNiSi25-21 / AISI 314) is an austenitic heat-resistant stainless steel containing 24.0–26.0% Cr, 19.0–22.0% Ni, and 1.5–2.5% Si. Its elevated chromium, nickel, and silicon content imparts exceptional oxidation resistance, scaling resistance, and high-temperature strength in hot air environments. It is widely used in furnace tubes, heat exchangers, industrial furnace structural components, petrochemical equipment, burners, and high-temperature conveyance systems. While its service temperature for oxidation and scaling resistance can reach up to approximately 1100–1150°C, the actual long-term operating temperature should be determined based on service media, stress levels, thermal cycling, and engineering design conditions.
GNEE supplies 1.4841 seamless stainless steel pipes tailored to project specifications, supporting customization in outer diameter, wall thickness, length, and tolerances, with inspection compliance according to TC1/TC2 requirements. Our standard supply capability covers outer diameters from approximately 6 mm to 830 mm and wall thicknesses from 0.5 mm to 48 mm (specific dimensions subject to production process feasibility and order confirmation). Each qualified batch is furnished with a fully traceable EN 10204 3.1 Material Test Certificate, with third-party inspection supported upon request.

Stainless Steel 1.4841 pipe Applications
Furnace Construction: High-temperature furnace components, conveyor belts, and rollers.
Chemical Industry: Cracking plants and heat exchangers operating at extreme temperatures.
Power Generation: Superheater tubes and boiler components.
Cement Industry: Kiln feed pipes and combustion nozzles.
What is the difference between 1.4841 and 1.4845?
1.4841 contains 1.5%–2.5% silicon (Si). The increased silicon content significantly enhances resistance to oxidation and carburization. It is harder than 310S and better suited for extremely oxidizing environments. 1.4845 has a lower silicon content (<1.0%), but its low carbon content results in better weldability.
Choose 1.4841 if your equipment faces severe temperature fluctuations or requires exceptional stability of the protective oxide layer; choose 1.4845 if ease of welding and cost are the primary considerations.
1.4841 stainless steel pipe Price per kg
The price of EN 1.4841 (AISI 314 / equivalent to 310S family) heat-resistant stainless steel pipe typically ranges from $3.50 to $8.50 USD per kilogram, depending on order volume, outer diameter, wall thickness, and whether the pipe is seamless or welded.
If you are willing, please provide the following information:
Required outer diameter and wall thickness
Total quantity (in kilograms or meters)

FAQ
Q:How to identify authentic 1.4841 pipes?
A:Check the Material Test Certificate (MTC): It must comply with EN 10204 3.1 or 3.2.
Check silicon content: Ensure the Si content is above 1.5% (standard 310S is only around 0.75%).
Check markings: The pipe body should bear markings such as "1.4841", "X15CrNiSi25-21", and "EN 10216-5".
Q:Can 1.4841 stainless steel pipe withstand high temperatures of 1200°C?
A:Continuous use: In air, the recommended maximum continuous service temperature for 1.4841 is 1150°C.
Short-term/limit use: It can withstand 1200°C for short periods; however, strength drops sharply at this temperature, and the protective oxide layer may begin to fail.
Q: Why does 1.4841 pipe become brittle after operating at high temperatures for a period of time?
A:When 1.4841 is exposed to temperatures between 600°C and 900°C for extended periods, a hard, brittle "Sigma phase" precipitates within its microstructure. While operation remains unaffected, the pipe becomes as brittle as ceramic upon cooling to room temperature, making it highly susceptible to fracture during impact or disassembly.
Q: What pressure can 1.4841 pipe (compliant with EN 10216-5) withstand?
A: The mechanical strength (yield strength) of 1.4841 decreases as temperature rises.
At 20°C, Rp0.2 is approximately 230 MPa.
At 500°C, it drops to approximately 120 MPa.
Calculation: You must refer to the design stress values for specific temperature ranges provided in EN 10216-5 and apply the wall thickness formula. Note: This material is primarily designed for high-temperature environments; its high-temperature creep rupture strength is significantly higher than that of standard 304 stainless steel.
