<![CDATA[Heat Treatment for Mold Steel — Complete Guide：核心技术要点、操作步...]]><p>Common heat treatment processes for mold steels:</p>

<ol>
<li>Annealing — stress relief, soften for machining</li>
<li>Quenching — harden to HRC 55-65</li>
<li>Tempering — reduce brittleness, adjust final hardness</li>
<li>Nitriding — surface hardening for wear resistance (0.1-0.3mm case)</li>
</ol>
