FCS 8407 Tool Steel
FCS 8407 is a high-quality hot work tool steel offered as an alternative to ASSAB 8407, with reference grades including AISI H13 or DIN 1.2344 (JIS SKD61). It is supplied under the FCS brand and is not original ASSAB material. It adopts a Cr-Mo-V alloying design, featuring excellent thermal fatigue resistance and high-temperature strength, as well as good machinability. It is widely used in mold manufacturing for applications such as die casting, extrusion, hot forging, hot stamping, and injection molding.
FCS supplies forged tool steel blocks and bars, with optional electroslag remelting (ESR). Ultrasonic testing (UT) and EN 10204 Type 3.1 inspection certificates are available upon request.
