1045H Steel Bar


1045H is a medium-carbon steel grade specifically treated through processes like hardening and tempering to achieve higher strength and hardness than standard 1045 steel. This grade is often used in applications that need a combination of strength and impact resistance. Ideal uses for 1045H include gears, shafts, bolts, studs, and other machine parts subjected to high mechanical stress.
