Minimum stannum ferrum iactum refert ad mixturam chalybem deiectam cum carbonis contento minus quam 0,45% et totum contentum aliorum elementorum mixturae non excedentes 5%. Humilis offensionis ferrum habet altitudinem roboris, bonam duritiem et duritiem. Ferrum mixturae humilis plerumque elementa mixturae continet, ut manganesum, chromium, cuprum, nickel, molybdenum, vanadium. Maiorem habent ictum duritiem, et per curatio caloris proprietates mechanicas melius obtinere possunt. Corrosio resistentia et resistentia attriendi admixto ferro iacto meliores sunt quam chalybe carbonis, qui pondus partium minuere potest et vitam servitutis augere.
