Description<br />
• <strong>Thermodur</strong>® <strong>2367</strong> <strong>Superclean</strong> is an electro slag<br />
remelted (ESR) hot work die steel developed for applications<br />
where high temperature properties (tensile strength<br />
& thermal conductivity) are required to resist thermal<br />
fatigue and tempering.<br />
Characteristics<br />
• Excellent resistance to heat checking<br />
• Excellent resistance to wear (erosion & abrasion)<br />
• Excellent high-temperature strength<br />
• Good tempering resistance<br />
• Good toughness<br />
Applications<br />
• High pressure die casting dies<br />
• Hot forging dies<br />
• Hot extrusion tooling<br />
• Forming dies<br />
• Plastic molds<br />
• Mandrels<br />

Polishing<br />
For highly cosmetic applications, the tool should be heat<br />
treated to the highest hardness possible. Size of the tool will<br />
determine the maximum hardness. A-1 polish is achievable<br />
when proper procedures are followed. A <strong>SCHMOLZ</strong> + BICK-<br />
ENBACH representative should be consulted when determining<br />
the hardness.<br />

Tempering (See tempering diagram on page 2)<br />
Temperature<br />
• Tempering hardness is approximate and based on two<br />
hours at temperature<br />
• In order to achieve faster quench rates, generous radii and<br />
machining stock should be left on during rough machining.<br />
• Optimal heat treatment parameters should be followed to<br />
achieve maximum potential die performance.<br />
• Please contact your <strong>SCHMOLZ</strong> + <strong>BICKENBACH</strong> heat treat<br />
representative for more detailed information.<br />

• <strong>Thermodur</strong>® <strong>2367</strong> <strong>Superclean</strong> can be welded in an annealed<br />
and hardened condition if machining errors, design<br />
changes or minor cracking have occurred. TIG (Tungsten<br />
Inert Gas) should preferably be used.<br />
