What is the effect of heating deformation on cast iron and 45 steel?
The thermal expansion coefficient of cast iron and 45 steel depends on the coefficient of linear expansion of the material (varies with the range of temperature),At 20---100 degrees, the coefficient of linear expansion of cast iron is 8.7---11.1, and the coefficient of linear expansion of steel 45 is 11.3---13.At 20---200 degrees, the coefficient of linear expansion of cast iron is 8.5---11.6, and the coefficient of linear expansion of steel 45 is 10.6---12.2.In the above-mentioned range, the deformation of 45 steel is relatively large.
The large deformation of cast iron, the metal from the perspective of capacity changes at different temperatures in cast iron iron carbon caused greater changes in the macro volume, the ideal understanding needs to have the corresponding knowledge of metal,
