UNI EN10219 Rectangular Hollow Section
EN 10219 S235JRH Steel Grade RHS tubes are utilized in various industries due to its
impressive list of features. For instance, this grade of Carbon Steel EN 10219 S235JRH Rectangular
Tube offers many good properties such as good conductivity, outstanding resistivity, while being sturdy
in nature. Also, since the carbon grade EN 10219 S235JRH tubes produced in our factory are manufactured
from good quality raw materials, it tends to be durable. The fore mentioned properties along with the long
service life of EN 10219 S235JRH Carbon Steel Round Tube make it an attractive, yet cost saving option for
our clients based in industries such as several petrochemical companies as well as those industries in the
energy sector.

| a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. | |||||||
