 8402 About 8402 steel, chromium - molybdenum - vanadium alloy tool steel, high and low temperature have good abrasion resistance, excellent toughness and ductility, stable and good and processing and polishing optical activity, excellent high temperature strength and thermal fatigue resistance, good hardenability, heat treatment size of a small deformation. 

 8402 is the use of special steel and steel-making technology, strict quality control and organization to get the high purity fine steel, 8407 the isotropic (isotropic) than the conventional refining system H13 better. This mold resistance to mechanical fatigue and thermal stress fatigue properties more valuable, such as die-casting molds, forging dies and extrusion tooling. Therefore, the use of mold hardness comparable 8407 to provide 1-2HRC Putuo H13 without sacrificing toughness. Hardness can reduce the occurrence of thermal cracking, to provide die life. Its advantages are as follows: 

 1 excellent thermal shock and anti-cracking ability; 

 2 high-temperature strength; 

 3. Regardless of the size of size, toughness and high ductility and isotropic; 

 4 processing and polishing of fine; 

 5 Excellent hardenability; 

 6. Good heat dimensional stability.
