  P20 Steel , alternatively referred to by its designation DIN 1.2311, is a general-purpose tool steel commonly used in the production of plastic molds, die-casting dies, and other tooling parts. Its well-balanced mix of hardness, toughness, and machinability makes it a go-to option in industries demanding strong and accurate tooling solutions. Chemical Composition of P20 Steel The standard chemical composition consists of: Carbon (C): 0.28% to 0.40% Manganese (Mn): 0.60% to 1.00% Chromium (Cr): 1.40% to 2.00% Molybdenum (Mo): 0.30% to 0.55% Silicon (Si): 0.20% to 0.80% This particular composition of elements gives P20 steel added strength, wear resistance, as well as the capability to sustain high stress in industrial use. Hardness and Mechanical Properties P20 Steel is usually supplied in pre-hardened condition, having a hardness between 28 to 34 HRC (Rockwell Hardness). This avoids the requirement for further heat treatment, and hence it is easy to machine and saves production ...
