EN 10025 S275JR Steel Equivalent

ASTM A36 is equivalent to EN S275JR steel plate. EN 10025 Grade S275JR is a non-alloy, low carbon, manganese-containing structural steel commonly supplied in the untreated or normalized condition. S275 material is available in plate and structural steel profiles. The EN 10025 standard is a six-part European structural steel standard that describes the properties of various structural steels.

What does S275JR Standard For? 

S275JR describes non-alloy structural steels and falls in Part 2 of the EN 10025 specification. The ‘S’ denotes a “structural steel” with a yield strength of 275 MPa. The ‘JR’ designation confirms that the material has undergone a Charpy V-notch impact test at 27 joules at room temperature.

Properties of S275JR Steel Plates

EN 10025 S275JR carbon steel plate has a specified chemical composition of 0.17 – 0.20 wt.% carbon (depending on thickness), 1.40 wt.% manganese, 0.55 wt.% copper, 0.012 wt.% nitrogen, 0.04 wt.% phosphorous and 0.04 wt.% sulphur.
Plate thickness has a major impact on elongation and yield strength. Elongation ranges from 26 % for plates less than 40 mm thick to 22% for plates thicker than 100 mm but thinner than 125 mm. Yield strength ranges between 360 and 510 MPa for plates less than 100 mm thick, and 350 – 500 MPa for plates thinner than 125 mm.

What’s the Application of EN 10025 S275JR? 

Grade S275JR steel plate is suitable for welding, bolted connections and riveting. It is readily weldable and bendable and suitable for non-critical structures. Its machinability characteristics are similar to that of mild steel. S275JR carbon steel plate is typically used in the construction of buildings and bridges, vehicle structures, and tools and cutters. Plates are particularly suitable for shipbuilding.
