Do stainless steel precision castings need to be operated at high temperatures?

The reason why stainless steel precision castings need to be operated at high temperatures is that high temperatures are conducive to the melting of inclusions and the floating of slag, which facilitates slag cleaning and degassing, and reduces slag inclusions and pore defects in machine tool castings.

What needs to be noted when using high temperature operation is that a reasonable stainless steel precision casting processing temperature should be determined according to the characteristics of the alloy to prevent the temperature from being too high, causing oxidation of the molten metal, intensifying gas suction, and causing defects such as burning loss of alloy elements and slag inclusions. ; You should also pay attention to the reasonable pouring temperature to prevent casting defects such as deflection, cracks, shrinkage and porosity.
