Because stainless steel casting cools and solidifies faster in a metal mold than in a sand mold, and the metal mold has no tolerance, the casting stress generated in the casting during metal mold casting is greater than that in sand casting, and the tendency for cracking is also greater. It is also easy to produce defects such as incomplete filling, cold shut, and white iron (for castings). Generally: (1) In order to prevent incomplete filling and cold shut in stainless steel casting, the following structural issues should be noted: A. The shape of the casting should be as streamlined as possible, avoiding sharp corners and abrupt changes in the structural shape, so as to facilitate the flow of molten metal; B. The wall thickness of the casting should be appropriate and not too thin, especially when the outline size of the casting is large...

Stainless steel is an alloy steel with a chromium content of at least 10.5%. It possesses high corrosion resistance and wear resistance, excellent processing performance, and a beautiful, decorative surface after grinding and polishing. When stainless steel first became popular in my country, people often distinguished it solely by its rust-resistance and non-magnetic properties. However, this is inaccurate and vague. There are many types of stainless steel, each with different uses, and their rust resistance, corrosion resistance, and magnetic properties vary considerably. Simple surface characteristics are no longer sufficient for differentiation. Below, we list the characteristics and elemental composition of some commonly used stainless steel alloys…
