CarTech No. 158 alloy is an exceedingly high strength, case hardening alloy mold steel. It is a cold-melt electric furnace process manufactured to a narrow range of analysis limits. Electric furnace melting, under closely controlled conditions, assures unvarying uniformity, or service. Each lot is hot acid etch inspected.

CarTech No. 158 alloy should be considered for jobs which require an extra measure of core strength. It possesses high strength core with uniform mechanical properties even up to 5" (125 mm) thick sections. It possesses highest mechanical properties of any case hardening mold steel.

The special alloy content of CarTech No. 158 alloy imparts excellent wear resistance. Dies withstand long runs or severe abrasion over much longer service without roughening of the mold surface.

Applications:
CarTech No. 158® alloy should be considered for use in for molds, cavities and cores requiring high case hardnesses and extremely high core strength. As such, it fits into applications which require long production runs.
