J2 and JR refer to the materials sub-grade its fracture toughness which is measured in joules of a materials toughness at a particular temperature. J2 is a material with a minimum of 27 joules at -20C while JR is a material with a minimum of 27 Joules at +20C (room temperature).. A JR material is normally used in an internal environment whereas a J2 is for external use.Table of material properties for structural steel S235 steel section jr j0 meansThe fracture toughness of steel is characterized in EN 1993-1-10 in terms of the KV(T) value i.e. the impact energy in Joules [J] required to fracture a Charpy V-notch specimen at a given test temperature T. Sub-grade JR correspond to a minimum KV of 27 J at Room temperature (+20°C). Sub-grade J0 correspond to a minimum KV of 27 J at 0°C.Structural steel grade designations according to EN JR indicates that the Charpy Impact Test was conducted to 27 joules minimum at room temperature. J0 indicates that the Impact Test was performed to 27 joules minimum at 0°C. J2 indicates that the Impact Test was performed to 27 joules minimum at 20°C.File Size: 191KBPage Count: 2
Structural steels are the most widely used among steels because of their sufficient qualities and comparatively low price. This combination makes them useful in different sectors. Every year, about 25% of structural steels are used in the construction of buildings.Mechanical engineers favour it when building machinery that does not have many special needs like high durability or resistance to heavy loads.Sometimes resistaSee more on fractory steel section jr j0 meansStructural Steel Sub-Grades JR, J0 & J2 Does It Matter?2.0 Sub-Grades JR, J0, J2.

May 11, 2012 · Structural steel is a standard construction material made from specific grades of steel and formed in a range of industry-standard cross-sectional shapes (or Sections). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.Structural Steel - EN10025 S275, S355JR and S355JOThe steel should be selected in accordance with the strength requirements.The JR, J0 & J2 suffixes refer to different impact requirements. An average impact energy value of 27 Joules must be achieved on full size specimens in the longitudinal direction in all applicable cases.

The inner surface of the upper and lower flanges of the I-beam has a slope, generally 1: 6, which makes the flanges thin outside and thick inside. As a result, the cross-section characteristics of I-beams in the two main planes are greatly different, and it is difficult to exert the strength in practical applications.
