A Guide to EN 10027 Steel Names

Steels produced to EN standards for example pressure vessel steels such as P355 or structural steels S275 have names that tell you a lot about the steel without having to look the details up in the relevant standard. The way that they are named in set out in EN 10027 and by following a few simple rules you should soon be a master of know steel properties from the grade alone BASIC ELECTRODE Vandal - Lincoln ElectricBasic coated low-hydrogen welding electrode with very good welding properties giving a tough, crack resistant weld metal.

STRUCTURAL STEEEL S275 JR,JO,J2 - Metal and Metallurgy

For J0 and J2, the Charpy impact test was performed with 27 Joules at 0 °C and 27 Joules at -20 °C, respectively. The class of steel (JR, J0 or J2) has little or nothing to do with the thickness chosen for a particular design but, on the contrary, for the material thickness selection, the Specified Minimum Yield Strength, has an important Steel material properties - SteelConstructionfoFor non-alloy structural steels the main designations of the subgrades are JR, J0, J2 and K2. For fine grain steels and quenched and tempered steels (which are generally tougher, with higher impact energy) different designations are used. A summary of the toughness designations is given in the table below. 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. Chemical Composition(max %)

Steel sub-grades JR, J0, J2, K2 characterize the ability of steel to behave in a ductile manner and therefore avoid brittle fracture, especially at low temperatures. The 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 Welcome to ChunWoTECHNICAL NOTE 007 Structural Steel Sub-Grades JR, J0 & J2 Does It Matter?

What is the difference between J2 and JR? Can they be used

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.
