S275 Structural Steel: Yield Strength and Properties

S275 Structural Steel has a specified minimum yield strength of 275 megapascals. The numbers below are the ones design and site work reach for.

Minimum yield strength: 275 MPa
Minimum yield strength275 MPa
Minimum tensile strength410 to 560 MPa
Elongationat least 23 percent
Density7,850 kg per cubic meter
Elastic modulus200 to 210 GPa
Typical usegeneral building steelwork

Notes for design and site

S275 was the default of building steelwork for decades and remains a comfortable choice where deflection or fatigue governs and extra yield strength would go unused. Availability now favors S355 in many markets, so check what the stockholder actually carries before the drawings commit.
