This kind of magnetic material offers the advantage of highyer of through hardness than other stainless steel materials, as well as a considerable resistance to corrosion against water, steam, oil, gasoline and alcohol.

All balls are passivated.

The high hardness, grade of surface finish, and extremely accurate tolerances ensure that this type of steel is suitable material to stainless steel precision ball bearings, oil refinery valves, ball-point pens and other rigid environmental applications.
