Mechanical properties:

Hardness: annealing, 255 ~ 207HB, indentation diameter 3.8 ~ 4.2mm
  
Heat treatment and use

Heat treatment: (Delivery Status: Brinell hardness HBW10/3000 (≤ 255 ~~ 207)), quenching: 1075 to 1125, coolant

: Oil;
Uses: used steel casting molds. Lower carbon content, high toughness and good thermal conductivity; contains more

Carbide-forming elements chromium, tungsten, vanadium, and the phase transition temperature is increased, so that the steel has a high temperature strength, hardness, and good thermal fatigue resistance

; Hardenability. Suitable for the manufacture of high temperature, high stress, but not shock loading of the die-casting of copper, aluminum, magnesium alloy with attached mold core, the gate

Sets, split nails, high should beat wax, hot shears, hot forging mold, flat forging machine punch, insert, etc.
