Carburizing Strategy:<\/strong>
\n8620 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. \ud301:<\/strong> Ideal for parts subject to high shock and heavy surface wear.<\/p>\n

\uae30\uacc4 \uac00\uacf5\uc131:<\/strong>
\nIn its annealed state, 8620 has excellent machinability (approx. 65% of 1212). It shears cleanly and responds well to standard carbide tooling. \ud301:<\/strong> Maintain sharp tools to prevent surface tearing.<\/p>\n

Distortion Control:<\/strong>
\nQuenching can cause dimensional changes. \ud301:<\/strong> We recommend leaving 0.2mm to 0.4mm of grinding stock on critical diameters to be finished \uc5f4\ucc98\ub9ac\ub97c \ud1b5\ud574 \uacbd\ud654\uc2dc\ud0a8<\/em> the hardening cycle.<\/p>\n

\uc6a9\uc811\uc131:<\/strong>
\n8620 can be welded easily in the annealed state using standard methods. However, welding after case-hardening is not recommended<\/strong> as it will destroy the surface properties.<\/p>\n<\/div>\n
