Standards Development
This document specifies the technical delivery conditions for flat and long products as well as semifinished products which are meant for further processing to flat and long products of hot rolled nonalloy quality steels in the grades and qualities given in Tables 1 to 5 (chemical composition) and Tables 6 to 8 (mechanical properties) in the usual delivery conditions as given in 6.3. Three engineering steels are also specified in this document (see Tables 2 and 4) (chemical composition) and Table 7 (mechanical properties). This document does not apply to structural hollow sections (see EN 10210-1 and EN 10219-1) and tubes.
The technical delivery conditions apply to:
— thicknesses ≥ 3 mm and ≤ 150 mm for long products of steel grade S460JR, J0, J2, K2 and S500J0;
— 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. Stress relieving is accepted. Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).
This document foresees that semi-finished products which are to be converted to rolled finished products conforming to this document are the subject of special agreements at the time of the order. The chemical compositions are also agreed to at the time of the order; the values are within the limits of Tables 1 and 2.
