Web2 de ene. de 2002 · Stabilized stainless steels or low-carbon type steels are preferred to avoid these effects. Full solution treatment of stainless steels, by heating to about 1080°C followed by rapid cooling, eliminates all residual stresses. However, it is not practical for most large or complex fabrications. WebA heat treatment carried out on ferritic steels at a relatively low temperature, below the lower transformation temperature; in a conventional structural carbon steel this would be in the region of 600-650°C. It reduces hardness, lowers the tensile strength and improves ductility and toughness.
