The strength grades covered by the BS EN standards include; S235, S275, S355, S420 and S460. ( BS 7668 covers one strength grade, S345.) Yield strengths above 460 N/mm are available to BS EN 10025: Part 6, but BS 5400 or other design codes do not yet cover the use of these strengths.
DETERMINATION OF FRACTURE TOUGHNESS FROM CHARPY IMPACT ENERGY: PROCEDURE AND VALIDATION British Steel plc One of the key inputs for any structural integrity assessment is the fracture toughness, usually determined by an appropriate fracture mechanics-based test. However, in many situations data are not available and cannot be generated.
S 275 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure it is a highly usable steel in your various projects. EN 10025-2 S275J2 High Yield Strength Structural Steel Plate . J0 syambol 0 temperature impact test. J2 symbol -20 temperature impact test . S275J2 Characteristic
Normally S355 will have following variation based on impact strength at different temperatures, as steel become more brittle when temperature drops. If your structure need to withstand -20C, it's better and safer to choose S355J2. S355JR - Can withstand an impact energy of 27J at +20C.
S275 steel is often used on railway bridges, where stiffness rather than strength governs the design, or where fatigue is the critical design case. S355 steel is predominantly used in highway bridge applications, as it is readily available, , prime quality stainless steel flat bar 304 310s 321 Charpy V-notch impact test piece

J0 indicates that the Impact Test was performed to 27 joules minimum at 0C. J2 indicates that the Impact Test was performed to 27 joules minimum at 20C. K2 indicates that the Impact Test was performed to 40 joules minimum at 20C. G3 indicates delivery conditions are at the manufacturers discretion.
Tensile test values apply to transverse direction only. S0 is the original cross-sectional area. 1. The impact properties of quality JR products are verified only when specified at the time of order placement. Impact tests are performed on full size specimens (greater than or equal to 10mm) in the longitudinal direction. 2.
S275 does not find much use and may be harder to find. S420 is suitable when looking for higher strength but may also not be readily available with every manufacturer. The hardness measures of all structural steels are quite low. If needed, those values can be improved by hardening. Classification and Impact Resistance
