Q How should 420 Stainless Steel Balls be maintained or stored?

A
Store in a dry, clean environment to prevent moisture-induced corrosion.

Avoid exposure to strong acids or chlorides (e.g., saltwater).

Clean with mild solvents or water-based cleaners; ensure passivation is intact for corrosion resistance.
Q What are the primary applications of 420 Stainless Steel Balls

A
Industrial: Bearings, valves, pumps, and check valves.

Automotive: Seatbelt mechanisms, lighters, and precision components.

Consumer Goods: Ballpoint pens, cosmetic applicators (e.g., roll-on deodorants).

Food Processing: Equipment requiring mild corrosion resistance.

Light-Duty Grinding: Grinding media in non-aggressive environments.
Q What are the main features of 420 Stainless Steel Balls?

A
1.High hardness (50–55 HRC).

2.Moderate corrosion resistance (resists fresh water, steam, mild acids).

3.High tensile strength (1600–1900 MPa).

4.Ferromagnetic properties for easy handling.

5.Cost-effective compared to 440C or 316 stainless steel.
Q What are 420 Stainless Steel Balls?

A 420 stainless steel balls are spherical components made from AISI 420 martensitic stainless steel, containing 0.15–0.50% carbon and 12–14% chromium. They are through-hardened (HRC 48–58) and passivated for enhanced durability and corrosion resistance, used in bearings, valves, and precision applications.

We help you avoid the pitfalls to deliver the quality and value your stainless steel ball need.
