Usually, if there is no special requirement for the surface, the product after investment casting is only coated with oil-proof and anti-rust paint to prevent rust. However, there may also be special purposes such as improving appearance, protecting surfaces from external influences, meeting special branding requirements, changing material properties, etc. In this case, some surface treatment...

Have you ever wondered why your stainless steel sheets will not corrode when exposed to water and air? This is because they are made of alloy castings. They help metals perform better. As a result, you are surrounded by it every day. Metals such as copper, iron, silver, and gold are often difficult to obtain in their purest form. Bronze, brass, steel and other alloys are common. A homogeneous...

the production process of investment castings, some defects of investment castings will inevitably occur due to some wrong operations. Here are some common investment casting defects and how to prevent them: 1. StomataBlowholes are pores that exist on the surface or interior area of ​​a casting. It can be round, oval, or irregular in shape, and is sometimes an air mass composed of multiple...

What is the difference between cast steel and carbon steel?1. Steel is classified by chemical composition(1) Carbon steel: a. Low carbon steel (C≤0.25%) b. Medium carbon steel (C≤0.25~0.60%) c. High carbon steel (C≤0.60%)Steel is classified by forming method: (1) forged steel (2) cast steel (3) hot rolled steel (4) cold drawn steel. The so-called cast steel and carbon steel are just...

Ductile iron (also known as ductile iron or ductile iron) is actually a group of irons that exhibit high strength, flexibility, durability and resiliency due to their unique microstructure. Ductile iron typically contains more than 3% carbon; it can bend, twist or deform without breaking. Its mechanical properties are similar to steel and far exceed standard cast iron.Ductile iron castings are...
