Heat Treatment
Isothermal annealing:
Heat to 850÷880;
Funace cooling to 770 and hold at temperature for at least 10 hours;
Cool by10/h to 720;
Cooling in air.
Stress relieving :
To be carried out after machining and befor the final heat trestment,
-Heat to 650÷700 , hold for 4/6 hours ;
-Furnace cooling to 330÷350
-Cooling in air
Hardening :
-Initial preheating to 350÷450;
-Second preheating to 750÷850 in sait bath at 850;
-Austenitizing at 960÷100;
-Cooling in air or in oil if large parts.
Quenched hardness:64÷65HRC
Tempering:
In the temperature range 150÷300 with minimum holding time 3h. For parts hardened at 1080÷1100, a first will be carried out at 500÷550 in order to expioit secondary handness, foliowed by a second tempering at 180/300
This kind of mold steel is apply to the plastic of PVC, PP, EP, PC, PMMA and food industry mechanical componentmold steel.And we have exported the plastic mold steel and hot-work die steel to Germany,UAS,France,Turkey and other countries qand areas and they gain the customers trust and have good reputation.
