Therefore, the heat-resistant steel with chromium as the main alloy element, silicon, aluminum as the auxiliary elements, in short, the high temperature oxidation resistens bilong ain i pas tasol wantaim kemikel komposesen.
High temperature strength refers to the ability of the steel to withstand the mechanical load for a long time at high temperature. Steel under high temperature mechanical load is softening, that is, the strength decreases with the increase of temperature. The second is creep, that is, under the action of constant stress, the amount of plastic deformation is slowly increasing with the extension of time, and the plastic deformation of steel at high temperature is caused by the internal crystal slip and the grain boundary slip.
