thicknesses 400 mm for flat products of qualities JR, J0, J2 and K2; thicknesses 250 mm for flat and long products of all other grades and qualities. The steels specified in this document are not intended to be heat treated except products delivered in the delivery condition +N.
Within the strength grades of the non-alloy steels given in Annex A, four qualities JR, J0, J2 and K2 are specified. These differ in respect of specified impact requirements, method of d eoxidation, limits on values of various elements, with particular reference to sulfur and phosphorus, and the inspection and testing requirements. BS EN10025 S275 /S355 /S420 /S460 - Steel Exporter BeBon BS EN 10025 has recently been revised (2004), and subsumes standards such as the 1993 versions of BS EN 10025, BS EN 10113, BS EN 10137 and BS EN 10155. Furthermore, designers may be more familiar with the material grades of old standards such as BS 4360, so comparisons are useful.However, it must be stressed that the new steels are not simply the old steels with new names - there are some

J2 is a material with a minimum of 27 joules at -20C while JR is a material with a minimum of 27 Joules at +20C (room temperature). A JR material is normally used in an internal environment whereas a J2 is for external use. If J2 is required you must not substitute JR.
