Bibliography
This European Standard specifies the tolerances on dimensions, shape and mass for semi-finished products intended to undergo hot forming by forging, i.e. blooms, slabs and billets made of:- general purpose steels, in accordance with EN 10250-1 to 4;- steels for pressure purposes, in accordance with EN 10222-1 to 5.It does not cover semi-finished products intended for drop forging which are covered by EN 10243-1.
