Micro Steel Ball 0.5mm G10 AISI440C SS Balls For Ballpoint Pen Use

Quick Details:

  • 440C stainless steel is wear resistant and can be heat treated to very high hardness ratings, surpassing the hardness of 440a and 440B stainless steel

  • Mirror-like finish provides a bright, reflective appearance

  • Grade 10

  • Precision tolerance

Detailed Description:


AISI 440C, W 1.4125, X105CrMo17


AISI Type 440C stainless steel balls afford the advantage of maximum hardness combined with corrosion-resisting properties. This hardness, together with precise geometry and fine surface finish, makes them especially useful for both bearing and valve applications in petroleum refineries and other severe environmental applications.

Consumable electrode vacuum melted (CEVM) and vacuum induction melted/vacuum arc remelted (VIM-VAR) material is available upon request. All sizes and grades of corrosion-resisting hardened stainless steel balls are passivated.


Chemical Analysis AISI 440C

C=0.86-1.21%, Cr=16-18%, Mn=max 1.0%, Si=max 1.0%, S=max 0.025%, P=max 0.025%, Mo=0.40-0.65%, Ni=max 0,75%, Cu=max 0,5%


Mechanical Properties AISI 440C

Ball hardness is controlled with an eight point range of 60-66 Rockwell "C" as measured on parallel flat surfaces. Also, Type 440C stainless steel balls are magnetic. Custom heat treating is available for special hardness requirements.

Tensile strength:

200 kgs/mm2

Yield strength:

193.2 kgs/mm2

Modulus of elasticity:

20.392 kgs/mm2

Hardness:

HRC 60 – 66

Density:

7,750 g/cm³


Application

Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are used in foodstuff, medical instruments, quick couplings, recirculating ball bearings, knotting devices, oil refinery devices.


Corrosion Resistance

The material resists to corrosion in contact with freshwater, steam, oil, petrol, alcohol. They are subjected to pitting corrosion in sea water environments. Poor corrosion resistance in acid environments.
