Stainless Steel Casting Process Details
The processing of stainless steel castings directly affects the quality of stainless steel castings. Although the general working process is similar, stainless steel casting is different from ordinary carbon steel casting. So what are the details that need attention?
1. In order to prevent the white hole phenomenon in the casting process of stainless steel castings, measures must be taken during the casting process, otherwise the wall thickness cannot be made too thin. Aluminum alloy, magnesiumalloy metal mold castings, casting fillet not less than 2-5m.
2. The casting slope of stainless steel castings should be slightly larger than the slope of sand castings. Generally it is 38-40% larger than the sand type.
3. The minimum wall thickness of stainless steel castings should be greater than that of sand castings because metal molds dissipate heat quickly.
4. The thickness of the inner wall and the inner rib of the stainless steel casting is generally 0.55-0.65 of the thickness of the connecting outer wall. In addition, since the inner wall (rib) is cooled slowly, cracks easily occur at the boundary between the inner wall and the outer wall when the casting shrinks.
