A temperature at tempering intervents intervents the microstructurad el evolution. Lower temperatures (around 150 ° C to 250 ° C) primarily relieve stresses with minimadel karbide formatioon. Higher temperatures (above 400 ° C) promote carbide coarzening and reduction in hardness. The choice of contexatures oth e desirede balancee.
