Description
S275JR Plates & Sheets
S275JR Plates is a EN 10025-2 standard compliant non-alloy structural steel grade S275JR is renowned for its exceptional tensile strength, impact resistance, and weldability. The letters “S” stand for structural steel, “275” for a minimum yield strength of 275 MPa, and “JR” for non-alloy, hot-rolled, or normalized steel, which provides good toughness for machinery, bridges, and general construction.
S275JR is a common European standard (EN 10025) for a non-alloy structural mild steel. It is known for good weldability, formability, and impact resistance, making it suitable for a wide range of construction and manufacturing applications.
EN 10025-2: S275JR is a steel grade under this specific European standard for non-alloy structural steels.
EN 10025-2: 2004 Hot rolled products of structural steels. Technical delivery conditions for non-alloy structural steels
Meaning of the S275JR designation :
The code contains information about the steel’s properties:
