This is similar to tempered martensite where much of the carbon has come out of solution and formed fine needles of … Webb7 okt. 2024 · The slow cooling process helps prevent thermal stress of the metal. Next, the metal part is maintained at a temperature of roughly minus 190 degrees Celsius for about a day. When it is later heat tempered, the metal part undergoes an increase of temperature up to approximately 149 degrees Celsius.
