oldest ST45 High Precision Seamless Tube Manufacturer, Wide size range in DIN 2391 ST45 pipes, find updated Price
DIN 2391 ST45 pipes are carbon steel pipes made for high temperature and pressure services. The material has carbon, silicon, manganese, phosphorus and sulfur in the composition. Multi Metals (India) is a leading manufacturer of the DIN 2391 ST45 Carbon Steel Seamless Pipes in various sizes and shapes. The material is well known for its long lasting service. The pipes are also very much cost effective.
The DIN 2391 ST45 High Precision Seamless Tube is used in petroleum, refineries, boilers, fertilizer industries and in heat exchangers. The applications are high temperature, high pressure and precision demanding. The DIN 2391 ST45 Carbon Steel Pipe standard covers pipes of outer diameters ranging from 4mm to 60mm and wall thicknesses ranging from 0.5mm to 8mm. The length of the pipes can range up to 6000mm. There are seamless and welded pipes in this specification and grade. The
Carbon Steel DIN 2391 ST45 Seamless/ Welded Pipes can be normalized, annealed, cold drawn (mandatory), cold drawn (soft) or cold drawn and stress released. The material has 255MPa minimum yield strength and 580MPa minimum tensile strength. The DIN-2391-ST-45 Steel Seamless Pipe has high thermal conductivity and is not affected by high heat welding procedures. But the appropriate filler material must be used with preheating while welding with high temperature welding procedures like electric arc welding.
