Excess moisture will produce an oxidizing atmosphere in the mold, promote excess gas evolution and lower permeability, cause high dry and hot strength, reduce mold hardness and result in poor flowability of the sand.
This phenomenon can be seen more easily when the rolling load values are converted into steel hot strength using an inverse hot rolling model, like Sims.
If hot strength is the main requirement such as in the machining of heat resisting alloys then M42 is used.
Molding first against the male tool chills the sheet enough to improve hot strength, Arrem says.
Any variation in temperature of the hot sheet dramatically affects the hot strength or elasticity of the plastic.
The latter can help reduce shrinkage and improve hot strength and heat-distortion resistance.
It exhibits good hot strength and creep resistance and is useful up to 3,002F (1,650C).
There is not a good test out there that tells me how to measure the quality of incoming resin that will relate to the hot strength of the material as it is processed.
This is because shell sands tend to combine the highest hot strength and resin level with the finest grain of any chemical sand.
The CDC process provides an inexpensive approach to manufacturing engine blocks by combining the wear and hot strength of alloy A390 on the bore surfaces with the advantages of castability and machinability of A356 in the main body of the component.
