SCM-420

Chromium, manganese, and molybdenum are added to SCM-420, a low-alloy, medium-carbon case hardening steel, to improve its strength and durability. Its tough and ductile core is preserved while a hard, wear-resistant surface is created through carburizing or induction hardening. SCM-420 is perfect for gears, shafts, axles, spindles, and pinions in automotive, industrial machinery, and engineering applications because of its exceptional fatigue strength, dimensional stability, and resistance to stress and wear. It also provides long-lasting performance and dependability.

Key Features
