Carbon steel is composed of hard surface and soft, durable inner core therefore is strong against physical impact.
It is relatively affordable in case where high priced chromium balls with fully hardened inner core are not needed.
Production scope : 1mm ~ 25.4mm
Applications : Caster (wheel), slide rail, bearing, toy, ball mill |
