DIN 17456 DIN17457 DIN 17459 GOST9941 Stainless Steel Pipe

If you are looking for stainless steel tubes according to DIN 17456, DIN 17457, DIN 17459 or GOST 9941 or precision seamless or welded pipes for the chemical, petrochemical, food, energy and mechanical engineering industries, Gnee offers ready-made stainless steel tubes manufactured in strict accordance with European and Russian standards, ensuring high strength, excellent corrosion resistance and precise dimensional tolerances.

 

What's the difference between DIN 17456, 17457, and 17459?
DIN 17456 covers seamless tubes for general applications.
DIN 17457 covers seamless tubes for pressure purposes.
DIN 17459 applies to precision tubes with tighter dimensional tolerances.

 

Are DIN and GOST standards interchangeable?
Not exactly - GOST 9941 is the Russian equivalent of DIN 17456, and both specify seamless stainless steel pipes for general and pressure use. However, chemical compositions and test methods may differ slightly.

 

GNEE Common in-stock grades include 1.4301 (304), 1.4404 (316L), 1.4571 (316Ti), and 1.4541 (321) - covering most industrial and marine applications,For standard dimensions (e.g., 25 mm × 2 mm × 6000 mm 316L pipes), Gnee ships within 7–10 working days with full export documentation and inspection photos.
