Rocker Arm
This micrograph displays the hardened structure of medium carbon steel used to transmit the rapid valve motion in an engine. The steel has been quenched and tempered, producing a classic martensitic microstructure uniformly formed from steel containing 0.3% to 0.5% carbon. This treatment gives the rocker arm exceptional strength and toughness, enabling it to withstand millions of cycles without losing performance or mechanical integrity.
