S275JR ist der baseline structural steel in der European EN 10025-2 standard, directly equivalent zu ASTM A36 in UNS practice. Yield strength von 275 MPa bei ambient temperature, mit Charpy impact testing bei +20°C (JR designation). Used für welded, bolted, und riveted structures in allgemein construction, bridges, und industrial buildings. Der JR suffix indicates 27J minimum impact energy bei 20°C — ein kritisch distinction von J0 (0°C) und J2 (-20°C) subgrades für niedrig-temperature applications.

Frequently Asked Questions
Was ist der ASTM equivalent von S275JR?
ASTM A36 ist der closest UNS equivalent, mit similar yield strength (250 MPa für A36 vs 275 MPa für S275JR). S275JR hat marginally higher minimum yield und tighter composition controls. Für structural applications, der two sind generally interchangeable, though project specifications kann require EN 10025-zertifiziert material für CE marking compliance in European construction.
