S2 tool steel balls combine high hardness, outstanding impact resistance and excellent toughness, making them suitable for drilling, mining and heavy-duty industrial applications exposed to severe impact and abrasion.
To Share:
S2 tool steel balls are widely used in applications requiring higher shock resistance and toughness than conventional carbon or bearing steel balls.
S2 tool steel balls are manufactured from shock-resistant alloy tool steel and heat treated to achieve a combination of high hardness, impact toughness and wear resistance.
Compared with conventional bearing steel balls, S2 tool steel balls provide superior resistance to mechanical shock and impact loading, making them suitable for demanding drilling and mining environments.
