Features: Pure steel quality due to vacuum degassing treatment
The screwing die is formed by forging, and the flat steel and round steel are formed by rolling at a high ratio of deformation. It is compact in structure, suitable for making the plastic molds requiring Polish or etch machining.
Porosity occurs if the thickness of rolled sheet is higher than 120mm. It is not recommended for use to the molds with mirror polishing requirements.
Application: Plastic moulds, backers, bolsters, die holders. Also suitable for other applications such as rails, shafts and wear strips.
Shape and size: Modules / flat steel:20-90mm*205-610mm
Delivery condition: EAF, Forged, Annealed, HRC30-33
Remarks: P20 should always be annealed after forging and before rehardening. Heat uniformly to 770/790°C. Soak well and cool slowly in the furnace.
