E355 ST52 honed tube is shaped in the form of a hydraulic cylinder barrel to hydraulic fluids allowing for movement of fluids in and out of the grade. These tubes cover the specification of ;ST52 steel cold drawn tube ;and precision steel tubes of seamless types. DIN2391 E355 Honed Tube is part of a hydraulic cylinder that has a smooth surface finish on the interior of the bore.
DIN 2391 ST52 is a precision mild or low carbon grade. The DIN 2391 ST52 NBK Tube ;is capable of withstanding high temperatures. These tubes are produced in the normalized condition in controlled setups. The ST52 S355 Annealed Tube ;is annealed above the upper transformation point. The annealed tubes showcase good tolerance to reducing environments.
