FAQ of Electroplated Steel Balls、Alloy Steel Balls、PP Plastic Balls
Q What are the benefits of electroplating?
AEnhances corrosion resistance (unlike uncoated carbon steel, which rusts easily), provides a polished aesthetic, and improves wear resistance (e.g., chrome plating for valves). Nickel plating also supports magnetic applications.
Q What’s the difference between solid and hollow PP balls?
ASolid balls are denser for valve/check applications; hollow balls (~1 mm wall thickness) reduce weight and evaporation in tanks, with better floatation. Both may have molding seams and resist UV with additives.
Q Why are they preferred for Alloy Steel Balls?
A
Bearings (90% of use), valves, pumps, automotive components (steering/seating), grinding mills, and high-pressure tools. Forged variants (e.g., 40Cr) for high-temperature/pressure valves.
Q What materials are used for Alloy Steel Balls?
APrimarily 52100 chrome alloy steel (1% carbon, 1.36% chrome), which hardens to 60–65 HRC. Other variants include high-speed tool steels, or martensitic grades for high-temperature use.
Q What are Electroplated Steel Balls made of?
AStart with low-carbon steel or chrome alloy steel blanks, which are then electroplated with metals like nickel for shine and corrosion protection or hard chrome for hardness. The base steel is cold-headed, flashed, and heat-treated before plating.
