EN 10025 S235JR VS S275JR carbon steel

EN 10025 S235JR VS S275JR carbon steel

EN 10025 S235JR and S275JR carbon steel are commonly used steel materials. From the steel grades themselves, we can also realize the strength of S275JR carbon steel is higher than that of EN 10025 S235JR steel. Below is for EN 10025 S235JR VS S275JR carbon steel.

EN 10025 S235JR VS S275JR carbon steel in chemical composition:

Grade C  (t≤16mm) Mn P S Cu N
S235JR 0.19 max 1.50 max 0.045 max 0.045 max 0.60 max 0.014 max
S275JR 0.24 max 1.60 max 0.045 max 0.045 max 0.60 max 0.014 max

EN 10025 S235JR VS S275JR carbon steel in mechanical properties:

Grade Yield strength ReH/(N/mm2) (t≤16mm) min Tensile strength Rm/(N/mm2) (3mm≤t≤16mm) Elongation A/%(3mm≤t≤40mm) min Charpy V test
Temperature/℃ Impact energy (Longitudinal)/J min
S235JR 235 360-510 26 20 27
S275JR 275 410-560 23 20 27

The carbon content of S275JR carbon steel is higher than that of EN 10025 S235JR steel, which ensure the former has higher strength. EN 10025 S235JR and S275JR carbon steel plates are produced by fully killed steel process, and supplied in normalized or controlled rolling condition.
