General Information
2083 is a martensitic stainless steel with high hardenability (good wear resistance) and excellent resistance to cold atmospheric corrosion and hot oxidation ( 660ºC). It also has good resistance to chemical products.
Characteristics
Corrosion-resistant plastic mould steel for processing chemically aggressive injection-moulding compounds, with good polishing and machining properties.
Application : This steel offers very good polishing properties. Mainly used in plastic mould requiring very fine ( mirror) polishing, and also for fine cutlery, surgery cutting tools and razor blades.
Delivered Condition : Annealed to max. 241 HB

% Chemical C 0.38~0.45 Si ≤ 1.00 Mn ≤ 1.00 Cr 12.50~13.50
Composition P 0.030 S 0.030 Mo 0.15~0.25
Heat Treatment
It is recommended to use vacuum furnaces or furnaces with controlled protective gas atmosphere in order to protect the steel against oxidation and decarburization.
Quenching has to be performed in order to get the best microstructure, tool performance and minimum distortion. A slow quenching rate is recommended to minimize distortion but the quenching rate has to be sufficient to avoid the formation of undesirable components like bainite or ferrite / pearlite.
Tempering must be carried out immediately after quenching at a temperature in accordance with the mechanical properties required.
