The high chromium steel 1.2080 is high carbon high chromium type ledeburite, carbon content up to 2%, so the impact toughness is poor, easy to rattle, and easy to form uneven eutectic carbides. There are a lot of elements Cr in 1.2080 steel, mainly formed 7C3 compounds (Cr·Fe), and carburizing type carbide are very few.
A lot of carbonization logistics into austenite when quenching. After quenching martensite with high hardness. A large amount of dispersed carbides precipitation from martensite after tempering. Because of its hardness is very high, thus improves the wear resistance of steel, Cr and the isothermal transformation curve shifts to the right, thus increase the hardenability of steel. Martensitic transformation point is low, there is a lot of mold steel retained austenite after quenching, reduces the deformation of the mold quenching. High-carbon high chromium 1.2080 steel, with high hardenability, less deformation hardening, high hardness, good wear resistance.
