AISI 420/420C Steel Balls
AISI 420/420C Martensitic stainless steel hardened balls offer good mechanical hardness and corrosion resistance. They are used in applications where the more rigid corrosion resistance requirements can be relaxed. They have fair resistance to fresh water, steam, oil, gasoline, blood, perspiration, and alcohol and food environment. Balls are provided in the passivated condition. Balls are available in AISI 420, AISI420B, AISI420C UNI X20Cr13, X30Cr13, X46 Cr13-W1.4021, W 1.4028,W1.4034-JIS SUS420J1, SUS420J2. Common application of AISI420/420C balls are Special bearings, anti-friction bearings, special valves & pumps, lighters, ballpoint pens, automotive seatbelts & components.
