8620 강

8620 합금강 제작 지침

Carburizing Strategy:
8620 is designed to be carburized. This adds carbon to the surface, allowing it to reach high hardness (60+ HRC) while the low carbon core remains ductile. 팁: Ideal for parts subject to high shock and heavy surface wear.

기계 가공성:
In its annealed state, 8620 has excellent machinability (approx. 65% of 1212). It shears cleanly and responds well to standard carbide tooling. 팁: Maintain sharp tools to prevent surface tearing.

Distortion Control:
Quenching can cause dimensional changes. 팁: We recommend leaving 0.2mm to 0.4mm of grinding stock on critical diameters to be finished 열처리를 통해 경화시킨 the hardening cycle.

용접성:
8620 can be welded easily in the annealed state using standard methods. However, welding after case-hardening is not recommended as it will destroy the surface properties.
