Characteristics and scope of application
The steel is a martensitic stainless steel with good machining performance. After heat treatment (quenching and tempering), it has excellent corrosion resistance, polishing performance, and high The strength and wear resistance make it suitable for manufacturing plastic molds that bear high load, high wear resistance and are under the action of corrosive media, transparent plastic product molds, etc., such as hot oil pumps, valve plates, valve bearings, medical equipment, springs and other parts.

Delivery status
Delivery status The steel is delivered in an annealed state. Forging oil quenched die steel has some crack sensitivity. It should not be heated quickly during forging heating. It is best to preheat at 10 degrees. The forging heating temperature is 10 degrees. The final forging temperature should be greater than 10 degrees. The upper limit temperature is used when forging steel ingots. The upper limit temperature is taken when the billet is forged
Annealing
Generally, annealing uses degrees, holding hours, in degrees/hour, cooled to degrees and air-cooled out of the furnace, isothermal annealing uses degrees of heat preservation and sales, and then insulated again, kept for hours, in degrees / hour, the cooling rate is cooled to a degree of air cooling out of the furnace, and the annealing hardness is
