ST45 Steel Seamless Pipe and 1.0408 Carbon Steel Seamless circular tubes supplier in India
The grade ST45 for the specification DIN 2391 is for carbon steel material that has excellent tensile properties. The DIN 2391 ST45 Pipe has cold-drawn steel components, and they come with attractive surfaces. The DIN 2391 ST45 Pipe is also known for its toughness and is tougher than the conventional hot-rolled steel pipes. The cold-rolled process performed on the ST45 material improves its dimensional tolerances. The method also improves the straightness and other physical properties of the DIN 2391 ST45 Tube.
The steel variant present in ST45 Steel Seamless Pipe has medium carbon, making these products quite modest. The Steel 1.0408 Material is mostly manufactured by hardening process with quenching and tempering. These processes are performed on focused and restricted parts of the pipes and tubes made with Werkstoff 1.0408 Piping Material. Also, the unattended heat treatments can also be performed on the DIN 2391 ST 45 Smls Pipe, which means they have normalized delivery conditions. However, variations are available in the Steel ST 45 Cold Finished Tube heat treatment, and sometimes manufacturers have to bring in a little change in its composition to enhance the overall properties.
The machinability of the DIN 2391 ST45 Carbon Steel Annealed Tube is also quite good and comparable to the products made of mild steel. However, the ST45 DIN 2391 Carbon Steel Honed Tube possesses low weldability properties. We are one of the most renowned Carbon Steel DIN 2391 ST45 Seamless Tube in India. Our products are known for their quality and affordability. We offer a worldwide supply of the Carbon Steel 1.0408 Precision Steel Tube.
The 1.0408 Carbon Steel Seamless circular tubes are famous across industries for delivering authentic performances. Our 1.0408 Steel pipes go through several inspections before getting delivered to the clients. We offer doorstep delivery.

ST45 Pipe Tolerances
DIN 2391 ST45 Pipe OD tolerance
For DIN 2391 ST45 pipe over 10 inch as special OD tolerance pipe, the OD shall within vary +1% /-1%.
Steel 1.0408 Pipe Thickness tolerance
Werkstoff 1.0408 Pipe Length tolerance
For DIN 2391 ST 45 Seamless and Welded pipe, if definite cut lengths are ordered, the length shall vary within -0mm / +6mm.
DIN 2391 ST45 Pipe Weight tolerance
- For DIN 2391 45 pipes NPS 12 (DN300, 323.8mm) and under, the weight should vary within -3.5% / +10%.
- For 45 pipes over NPS 12 (DN300, 323.8mm), the weight should vary within -5% / +10%.
- DIN 2391 45 Pipes of NPS 4 (DN100, 114.3mm) and smaller sizes may be weighed in convenient lots; Steel 1.0408 pipe in sizes larger than NPS 4 should be weighed separately.
ST45 DIN 2391 Pipe Quantity tolerance
Normally DIN 2391 ST45 Pipe manufacturers take -10% to +10% tolerance, but Trident Steel keeps ±3% variation.
