What is P20 steel?
DIN 2311 is the Pre Hardened Plastic mould steel hardness distributed evenly in large cross sections that have excellent weldability with least hardness elevation, good mirror polishability and less streak texture making finishing easier. Size Section availability upto 255mm thickness. Supply hardness is 240-280 BHN.

Can you harden P20?
P20 Is also available at an annealed hardness of about 200 Brinell. It can be hardened or carburized up to a higher hardness of 50/60 RC when used for compression or transfer work. … When carburized, P20 is used for compression, transfer, and other types of molds requiring high surface hardness.
Can you weld P20 steel?
Some filler metals weld too hard as compared with the base metal. P-20 is one such material, with an as-welded hardness of 50-55 RC.
