2.How are Investment Castings Made?

Developing investment castings involves creating an original wax model, coating the image with plaster and building successive layers until strong shell envelopes the model. After melting out the wax, the molten metal will be poured into the mold, creating a perfect duplicate of the original wax pattern. Compared to machining apart, investment casting can economically offer undercuts, high definition, complex detail and a smooth surface finish.

Most often, investment casting is the only way a part can be economically manufactured.

3.The difference between carbon steel and stainless steel

Difference 1: Corrosion resistance

The most obvious difference between carbon steel and stainless steel is its resistance to corrosion. Both Carbon steel and stainless steel contain iron, which produces oxidation when exposed to the environment, resulting in rust. The chromium added to stainless steel makes it more corrosion-resistant than carbon steel. When chromium adheres to oxygen, a chromium oxide layer will be formed to protect the rest of the material from degradation and corrosion. Carbon steel is usually not enough.

Therefore, if corrosion resistance is the key factor, then stainless steel is the best choice.

Difference 2: Mechanical properties

Due to different types and grades, it is difficult to make a comprehensive statement of the mechanical performance differences between carbon steel and stainless steel. Stainless steels are more malleable than carbon steels because they usually contain more nickel.

Difference 3: Cost

Another important consideration is the cost difference between carbon steel and stainless steel. The cost of different grades varies, but stainless steel is usually higher than carbon steel.

This is mainly due to the addition of various alloy elements to stainless steel, including chromium, nickel, manganese, etc. These additional elements increase the cost of carbon steel.
