CARTECH MICRO-MELT 440-XH (High-Carbon, Cr-Mo-V-Ni, Alloy Tool Steel)

摘要

CarTech Micro-Melt 440-XH is an air-hardening, high-carbon, high chromium, corrosion resistant alloy tool steel that is produced by the powder metallurgy process. It can be considered as either a high hardness Type 440C martensitic stainless steel or a corrosion- resistant Type D2 alloy tool steel. CarTech Micro-Melt 440-XH possesses corrosion resistance equivalent to that of Type 440C martensitic stainless steel and can attain a maximum hardness of 64 HRC. In addition, the composition of CarTech Micro-Melt 440-XH has been balanced so that it can attain a minimum hardness of 60 HRC when air cooled from the hardening temperature.
