Aisi D2 Steel Round Bar Sheet Plate Din 1 2379 Jis Skd11 - China

d2 steel application

1.2379 steel is used for blanking or forming dies, thread rolling dies, shear knives, food-processing knives, gauges, punches and etc.

d2 steel round bar sheet plate heat treatment

heat treatment din 1.2379 steels alloy should be preheated very slowly to 815℃ (1500°f) and the temperature can be increased to 1010oc (1850°f).

then held at 1010oc (1850°f) for 20 to 45 minutes and air-cooled (air quenched).

annealing annealing of 1.2379 tool steels material should be done at 871 to 898°c (1600 to 1650°f) followed by slow furnace cooling at 4.4°c (40°f) per hour or less, after which cooling rate could be increased.

at the same time, must do something to prevent excessive carburization or decarburization.

stress relieving heat it slowly to 1050°-1250°f, allow to equalize, and then cool in still air(strain relieving) preheat prior to hardening preheat slowly to 1350°-1450°f and hold at this temperature until steel 1.2379 steel material is uniformly heated.

hardening after thorough preheating, heat to 1800°-1850°f.

hold it at the hardening temperature until it is completely and uniformly heated.

quenching din 1.2379 steel tool material is an air hardening steel and will develop hardness on cooling in still air.

to avoid scaling and prevent decarburization on the surface, controlled atmosphere or vacuum furnaces are recommended.

parts should be allowed to cool to 150f, or to where they can be held in the bare hand, and then temper immediately.

tempering the tempering temperature on material 1.2379 steel may be varied according to the desired hardness.

1.2379 steels can be tempered at 204°c (400°f) for achieving rockwell c hardness of 61 and at 537°c (1000°f) for a rockwell c hardness of 54 - compare chinese cr12mo1v1 steel, american d2 steel, japanese skd11 steel, the chemical composition of them is the same, but the performance is very different.

after heat treatment, the color of cr12mo1v1 is a little orange-red, and the deformation would be large.

it is easy to fracture during use.

and the hardness of d2 steel is higher than skd11 steel, but the toughness is not better than skd11 steel.

skd11 steel is light and smooth, with the best overall performance.
