The advantages and disadvantages of DIN 1.2080 steel

    The 1.2080 steel is a kind of cold work die steel of high carbon and high chromium. The  content of C and Cr is very high, respectively C 2.00%~2.30% and Cr 11.00%~13.00% (mass fraction). DIN 1.2080 steel belongs to the ledeburite steel, so it has a very high hardenability, hardened and wear resistance, quenching deformation of small. But when the carbide heterogeneity, Its deformation are multi direction and irregular, its main drawback is poor organization. Uneven carbide is difficult to improve by heat treatment method, unless use powder metallurgy to manufacturing. Impact toughness is poor, thermal conductivity and high temperature plasticity is poor, when thermal processing should pay attention to heating and forging process.
    The 1.2080 steel is one of the international common cold work die steel, but in recent years has gradually been better steel replaced, such as Cr12MoV, Cr12Mo1V1 or matrix steel. The same type of foreign steel is 210Cr12 (ISO), Japan SKD1 (JIS), America D3 (AlSI/SAE) etc..
    1.2080 steel mainly for High wear resistance and impact load is smaller cold punching mould parts (the convex and concave mold, cold extrusion concave mold etc.), because of its obvious advantages and disadvantages, the use of limited.
