DIN 2391 ST37 Pipe

ST37 Seamless Pipe and DIN 1.0037 Annealed Tube supplier in Mumbai

Pipes of ST37 are low-carbon steel pipes. The DIN 2391 ST37 Pipe is made up of a chemical composition of silicon, carbon, manganese, sulfur, and phosphorous. These pipes have been designed with excellent corrosion and oxidation resistance properties. The ST37 Seamless Pipe possesses excellent mechanical properties. These pipes possess a tensile strength of minimum 420Mpa and yield strength of minimum 315Mpa. The ST37 Seamless Steel Pipe is very strong as they are produced without any seam or welds. They are available with an outer dimension between 4mm to 60mm and a wall thickness of 0.5mm to 8mm. ST 37 NBK Honed Tube plays an important role in hydraulic systems. These tubes have excellent hardness and a good finish due to the abrasion-resistant rocks used in polishing them. The ST37 Tube is widely used in building various structural systems, construction, oil and gas refineries and transportation, construction, petrochemical industries, etc. We are the leading stockist of DIN 2391 ST37 Pipe in India. We keep stock of some of the best products, which are available at feasible rates.

DIN 2391 ST37 Pipe

The DIN 2391 St37.4 NBK Welded Tube is produced by joining pieces of steel together. These tubes have a long life and are available in single random, double random, and custom sizes. DIN ST37 Seamless Tube can be easily used in flanging and bending operations. These tubes are cost-effective and highly efficient in their work. They are available in lengths up to 6000mm. Mild Steel ST 37 Seamless Steel Tubes possess a carbon concentration between 0.30% to 0.60%. These tubes can be easily elongated by 14% and still possess excellent workability. These tubes can be customized in different shapes. The ST37 DIN Seamless circular tubes are the preferred tube choice due to their exceptional stress resistance properties. These pipes are widely used in various structural applications. DIN 2391 ST37 Carbon Steel Plain end seamless steel tubes are used in small diameter piping systems due to the 90 degrees angle in the tube run. These tubes can be easily attached to slip-on flanges and socket-weld connections in the system. The ST37 S235 Cold Finished Tube can be used in high-temperature and sub-zero systems. These tubes are available in all schedules and can be coated or galvanized for added protection. The ST37.0 Piping Material is used in extreme environments and high wear and tear applications. This material provides the pipes and tubes excellent strength and durability. We make use of the latest technology and the best ST37 Steel Material while producing the best products in this grade.

The DIN 1.0037 Annealed Tube is highly resistant to corrosion and abrasion. These tubes possess excellent ductility and good workability. Apart from this, they also have good magnetic properties. The ST37.8 Precision Steel Tube is a special category of tubes in the whole grade of steel tubes. These tubes are designed with excellent dimensional accuracy and enhanced strength. DIN 17100 St 37-2 Seamless Precision Steel Tubes have good corrosion resistance properties. These tubes are leakproof and are used in various domestic and industrial systems. They are available in hot or cold rolled finish. The DIN 17100 St 37-3 cold drawn high precision seamless tube is cold rolled after the hot-rolling process. In this process, the tubes can be enhanced with better properties and with an excellent finish. All our products including, the DIN 2391 ST37.4 Steel pipes can be customized in different shapes and sizes as per your requirements.
