The S275 steel specification covers several grades of carbon steel plates for general application such as coldforming, i.e. bending, folding, bordering and flanging.
The steel grades of the JR, JO and J2 categories are in general suitable for all welding techniques.
Width: from 1,500mm to 4,100mm
Length: from 6,000mm to 20,000mm
S: Structural steel.
E: Engineering steel.
235: Minimum yield strength (Reh) in MPa at 16mm
JR: Longitudinal Charpy V-notch impacts 27 J at + 20°C
J0: Longitudinal Charpy V-notch impacts 27 J at 0°C
J2: Longitudinal Charpy V-notch impacts 27 J at - 20°C
+AR: Supply in as rolled conditions
+N: Supply in normalized/normalised rolled conditions
Z: Grade with improved properties perpendicular to the surface
