Four relevant details to be noted in stainless steel casting process

The treatment of process details in stainless steel castings directly affects the quality of stainless steel castings. Although the general working process is similar, stainless steel casting is different.

There are detailed differences among stainless steel casting manufacturers, which are important factors affecting the quality of stainless steel castings. So what are the details to pay attention to?

In order to prevent the occurrence of white spots in stainless steel castings during the casting process, measures must be taken during the casting process, otherwise the wall thickness cannot be made too thin. Aluminum alloy and magnesium alloy metal mold castings, with rounded corners not less than 2-5m.

The pouring slope of stainless steel castings should be slightly greater than that of sand castings. Generally, it is 38-40% larger than sand molds.

The minimum wall thickness of stainless steel castings should be greater than that of sand castings because metal molds dissipate heat quickly.

The thickness of the inner wall and ribs of stainless steel castings is generally 0.55-0.65 of the thickness of the connecting outer wall. In addition, due to slow cooling of the inner wall (ribs), cracks are prone to occur at the junction of the inner and outer walls during casting shrinkage.

The above are four points to note for stainless steel castings. Only by grasping the details can we avoid phenomena such as white mouth and cracks in precision castings.
