Which Materials are Hardened for Automotive Parts?
Aluminum, steel, copper, titanium, and plastics are the most commonly used materials in the automotive industry. Titanium is employed in high-temperature areas, aluminum offers a high strength-to-weight ratio, and steel is famous for its body structure.
Steel alloys are the most common material hardened for automotive applications. Various vehicle components rely on the induction hardening of steel to meet the required properties. It increases the hardness, strength, impact resistance, and durability. It is recommended to use carbon steel with at least 0.35% carbon in induction hardening for automotive applications.
It might become confusing if you are more familiar with alloy grade than carbon content. Then, the following alloy series can be subjected to induction hardening for automotive applications; 1045, 1050, 1144, 4140, 4150, 4350, 5150, and 8650.
