T8-T10A hot rolled steel round bars

Classification :

T8, T10 and T12 are carbon tool steels. They are very hard. The Brinell hardness in annealed state is more than 300.Manual saw blade is T12 material, just quenching, hardness is greater.10 and 20 are low carbon, high quality structural steel, very soft, Brinell hardness is less than 155.Therefore, the fitter saw, laborious, the saw is very easy to wear.
