CarTech Micro-Melt 440-XH Steel

CarTech Micro-Melt 440-XH Steel

Steel name: Micro-Melt 440-XH
Diagram No.: 2307
Chemical composition in weight %: 2.25% C, 0.90% Si, 0.50% Mn, max. 0.030% S, 12.80% Cr, 1.30% Mo, 9.25% V
Steel group: PM tool steels
Properties: CarTech Micro-Melt 440-XH alloy is powder metallurgy, air-hardening, high carbon, high chromium, corrosion-resistant alloy. It can be considered either a high hardness 440C stainless steel or a corrosion-resistant D2 tool steel. CarTech Micro-Melt 440-XH alloy possesses corrosion resistance equivalent to 440C stainless steel and can attain a maximum hardness of 64 HRC. In addition, the composition of CarTech Micro-Melt 440-XH alloy has been balanced so that it can attain a minimum hardness of 60 HRC when air cooled from hardening temperatures of 1850 to 2000°F (1010°C to 1093°C). CarTech Micro-Melt 440-XH alloy is thus more forgiving during heat treatment than similar alloys.
Applications: CarTech Micro-Melt 440-XH can be used for specialty knives where the alloy's fine carbide distribution can be used to produce a keenly sharp cutting edge. The material can be easily ground to the thin profiles required for cutting tools. CarTech Micro-Melt 440-XH knife blades can be finely polished to high luster or produced with a uniform matte finish. Other applications that may be considered for this alloy include all applications for stainless steels that may require higher hardness, such as bearing assemblies, needle valves, ball check valves, valve seats, pump parts, ball studs, bushings and wear-resistant textile components.
