The quenching steel casting must be tempered in time, and the hot steel casting must be tempered when necessary. The performance of the steel casting after tempering depends on the tempering temperature, time and times. With the increase of the tempering temperature and the extension of the time, in addition to eliminating the quenching stress of the steel casting parts, the unstable quenching martensite is converted into the tempering martensite, support or sotensite, so that the strength and hardness of the cast steel are reduced, and the plasticity is significantly improved. For some alloy elements containing strong carbide formation (such as chromium, molybdenum, vanadium and tungsten, etc.), the phenomenon of increasing hardness and toughness decrease long 400~500 digri ol i kolim sekonderi haten, em olsem, hat bilong kast stiel long tempering stet i kamap long maksimum veliu.

Brittleness at 250 to 400℃: Cast steel quinto martensitissue produces tempering brittleness in this temperature range. If slightly higher than this brittle temperature area tempering, this tempering fragility can be eliminated. And later in the above temperature range, there will be no tempering brittleness, so it is often called the first type of tempering britelnes.

5. Solid solution treatment: Solid solution treatment is a heat treatment process of heating the casting to the appropriate temperature and insulation, fully dissolving the excess phase, and then rapid cooling to obtain the oversaturated solid solution. The main purpose of the solid solution treatment is to dissolve the carbide or other precipitated phase in the solid solution to obtain an oversaturated monophasic organization.
