Calor curatio processus 9Cr2Mo forgings

9 cr2mo materiarum typicarum Cr2 frigidum volvulum chalybeum principaliter in usu industriae in fabricando frigido involutum cum cylindro frigido mori et ferrum cudendo etc. Sed multi dicunt ignorantes de cr2mo caloris 9 modum curationis, ideo hic maxime. loqui de 9 cr2mo caloris curandi methodo, sperandi sphaeroidationis furnum: 1 790 ~ 810 calefactionis, isothermal, 650 ~ 670, 500 ex aeris refrigeratione; 2 exstinguendi: calefactionis temperaturae =880~900, infrigidationis exstinguendi: secundum varias falsas. et diversis requisitis, medium refrigerationis sicut aqua exstinguitur PAG oleum fluidum adhiberi potest.
Nota: malleationes typicae sunt Cr2 frigidum volumen chalybe.
