S275JR Carbon Steel Plate

S275JR steel plate,S275JR grade steel is a readily weldable low carbon manganese steel with good impact resistance. This material is commonly supplied in the untreated or normalised condition. Machinability of this material is similar to that of mild steel.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.
