Abstract
Stretching method of the steel comprising the fixing and immobilization on the press row, provided with grooves, and possibly on the needle of the press, also provided with grooves, a lubricant formed by an agglomerate of an undecomposable pulverulent substance the temperature of 1300ºc, and that is not alloyed at this temperature with steel.
