ST 45 Steel Tube

ST 45 Steel Tube

ST45 DIN 2391 Carbon Steel Welded Tubes and DIN 2391 ST45.4 / ST55 Pipe supplier in India

ST45 is a low carbon grade of steel. The ST 45 Steel Tube is designed with a chemical composition of carbon, silicon, manganese, phosphorous, and sulfur. The content embedded in these tubes gives them excellent corrosion and oxidation resistance properties. An ST 45 Steel Pipe has modest strength and the material in these pipes can be maneuvered to increase the hardness by inducing quenching and tempering processes. The pipes can also be subjected to induction hardening, where the hardness property of the material will go up to 55 HRC. The versatile DIN 2391 ST45.4 / ST55 Pipe is designed with outer dimensions between 4mm to 60mm and has a wall thickness in the range of 0.5mm to 8mm. These pipes can be availed in maximum lengths up to 6000mm max. The cold drawn ST 45 Material is designed with a minimum tensile strength of 580mpa and can be easily elongated by 5% in the system and still possess enhanced workability. The material can be customized in different shapes and sizes to suit all our customer's requirements. Carbon Steel DIN 2391 ST45 Pipes are widely seen in petroleum, oil and gas, power generation, high temperatures or pressure lines, etc.

The DIN 2391 ST45 Seamless Tube is produced as hot steel billets are passed through extruded metal to precisely shape them. These tubes have enhanced strength and outstanding load-bearing capacity in comparison to other tubes in this grade. ST45 DIN 2391 Carbon Steel Welded Tubes are produced by rolling pieces of sheet or strips and welding them in place using standard welding procedures. These tubes offer a cost-effective solution to seamless tubes but are only preferred in low pressure and temperature applications. If you have any questions or queries about these products or their pricing, contact us for more information.
