j0 certified steel to be equivalent as j2
J0 syambol 0 temperature impact test. J2 symbol -20 temperature impact test . S355J0 Characteristic. S355J0 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process
Oct 19, 2020 · In the example of S355 J0 the zero simple means that at least 27 Joules is required to break the sample at 0°C in the standard Charpy test. By comparison, a JR steel achieves 27 Joules at room temperature (20°C) while a J2 absorbs 27 Joules at -20°C. Brittle fracture 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.
S275 J0 Grade 43C S355 J0 Grade 50C S275 J2 Grade 43D S355 J2 Grade 50D 2.0 Sub-Grades JR, J0, J2 Steel sub-grades indicate the Charpy impact value required to prevent brittle fracture. JR Longitudinal Charpy V-notch impacts 27J at Room temp J0
