EN 10025 S275 Steel (S275JR, S275J0 & S275J2)

EN 10025 S275 Steel is a non-alloy structural steel grade, according to EN10025, S275 mild steel is mainly devided into S275JR (1.0044), S275J0 (1.0143) and S275J2 (1.0145). Some properties of S275 mild steel is better than S235, and lower than S355.

S275 material old designation is St44 according to Germany standard, former quality grade equivalent is as follows:

• EN10025 S275JR (1.0044) - St44-2 in DIN 17100
• S275JO (1.0143) - St44-3U in DIN17100
• S275J2 (1.0145) - S275J2G4 in EN 10025: 1993

EN10025 S275JR Meaning (Designation)

The lists below explains EN10025 S275JR meaning

• "S" is for structural steel;
• "275" refers to the minimum yield strength is 275 MPa tested with steel thickness ≤ 16mm.
• "JR" means that the minimum charpy impact value at room temperature is 27J.
• "J0" refers to the minimum charpy impact value at 0 °C is 27J.
• "J2" means the minimum impact value at -20 °C is 27J.
