DIN 2391 Seamless Cold Drawn Steel Tube for Mechnical Processing Purpose ST35 ST37
OVERVIEW
We are distributors, Dealers, stockists, exporters and suppliers of world class ST35 & ST 35.8 steel pipe and we deliver these pipes to our clients located in all corners of the globe. To ensure that our ST 35 steel pipes meet the highest quality standards, we manufacture them using the highest quality raw materials and we also run them through the most rigid quality parameters. We also supply our clients with Material Test Certificates (MTC), as per EN 10204 3.1 and EN 10204 3.2. For all your needs for EN 10305 ST 35 steel pipe, no matter where you might be located in the world, be sure to contact us, we assure you of the best price and the best quality and service.
- DIN 2391 ST 35 steel pipe are also called mild steel tubes or mild steel pipes. These pipes and tubes are very popular as they cost less.
- Another reason why these Mild Steel pipes and tubes are in very big demand is because they are easy to shape & form.
- ST35 mild steel pipes have a minimum manganese content of 40% and a maximum carbon content of 17%.
- ST 35 carbon steel tubes are manufactured by the cold rolled process or by the cold drawn process.
- ST 35 steel pipe are commonly known as MS pipes or CS pipes and they are manufactured by us in accordance with DIN Specifications.
- ST35 steel tube are not as hard as carbon steel pipes, but with the process of carburizing, it is possible to increase their surface hardness. These pipes have the capacity to withstand very high pressures and they also have high-temperature resistivity.
- ST 35 pipes can be procured from us in various forms, sizes, shapes and thicknesses and they are also tailor-made by us, to meet specific needs of clients.
- We provide these ST 35 steel pipes in accordance with the specific needs of customers and pack them as per the requirements of customers, for export orders, to any place in the world. To build these pipes and tubes, we make use of the very latest cutting edge technology.
- Our DIN 2391 ST35 steel pipes are highly efficient, extremely durable and they are available at very affordable prices.
APPLICATIONS
ST 35 steel pipes are wildly used by maunfacture of pipelines,vessels,equipment,pipe
fittings and steel structure.

DELIVERY CONDITIONS
Designation | Symbol | Description |
Cold finished/ hard | BK | Tubes do not undergo heat treatment following the final cold forming and thus have a rather high resistance to deformation |
Cold finished/ soft | BKW | The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming |
Cold finished and stress relieved | BKS | Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree |
Annealed | GBK | The last cold forming process is followed by anneling above the upper transformation point in a controlled atmosphere |
Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
