FDAC special alloy die-casting mold 
 Hitachi special alloy die-casting mold 

 Mainly as (%) C C :0.33-0 .42; Si Si :0.80-1 .20; Mn Mn 0.55-0.75; Cr Cr :4.80-5 .50; Mo Mo :1.20-1 .60; V V :0.30-0 .80; P P: 0.030 the following; S S :0.10-0 .15 below; cutting of elements: a number of 
 Department of steel properties FDAC DAC (JIS SKD 61) as the basic ingredients, add the cutting of the other alloys, with a special solution method has been manufacturing cutting of hardened steel pressing mold. 
 Features 1. Has been quenched and the use of hardness HRC40-44 the most suitable 
 2. To be cut is very good, easily processed, cut short the time for mold 
 3. Does not require machining after hardening, quenching distortion-free, especially cracking, scaling, etc. 
 4. The use of hazardous ingredients are very low impurities YSS sponges as the raw material of fine weaving of special alloy steel, hot compression molded 
 5. High resistance to thermal cracking, high temperature strength of good, long life steel 

 Applications: Hot, zinc, aluminum, magnesium, aluminum die-casting mold and plastic mold and has processed no quenching and deformation of the characteristics, should be made after the emergency precision molds or mold of the advantages of a short time.
