Liquidity is about the capacity of stainless steel Precision Valve Casting with mold. For thin casting with complex shape, require higher liquidity, otherwise, cannot fill the entire mould. The precision liquidity Stainless steel mainly depends on its chemical composition and casting temperature on. For example, eutectic or near eutectic composition of an alloy and the end product of a narrow temperature range trouble alloys have good fluidity; in casting, phosphorus can improve the liquidity, sulfur makes the liquidity worse. In addition, improve the pouring temperature can also improve the liquidity.
The phenomenon of liquid stainless steel precision in the cooling, reducing the volume, is known as shrinkage. The main factor affecting the shrinkage is the precision chemical composition of stainless steel. Due to the contraction affects not only the size, and may make the casting shrinkage hole, osteoporosis, internal force, deformation, and cracking defects. So, for the precision Metal Casting of stainless steel, the less shrinkage is the better.
