Extractors are normally hardened to resist wear. Hardened parts can chip if they are hit wrong.
I thought they might be spring steel so they can flex.
They are high carbon steel, heat treated by heating, quenching, and then re-heating to a specific lower temperature. "Spring Steel" is steel that is hardened and drawn to produce the desired properties. 1911 extractors are a "spring". But abusing them by having them snap over a rim in the chamber will usually result in de-tuning (bending) them, requiring re-bending them. The usual failure mode is bending, not usually breaking or chipping, but it can and does happen.
