The impeller refers to a rotating body with blades that transmits energy to the liquid, and can also refer to the general term for the wheel disc and the rotating blades installed on it.

The alkali metal explosion cleaning process, also known as high temperature alkali metal explosion, its basic working principle is: put the casting into a caustic soda solution with a temperature of 750-800℃ and a mass concentrati...

Martensitic stainless steel refers to a type of stainless steel whose microstructure is mainly martensite. The chromium content of martensitic stainless steel is in the range of 12%-18%, and its main alloying elements are iron,...

Monel is the brainchild of Robert Crooks Stanley of International Nickel Corporation. It was patented in 1906 and named after the company's president Ambrose Monell. The second "L" was deleted from the metal name because i...

The foundry industry is one of the basic industries of the entire industry. Casting plays an increasingly important role in the field of modern machinery. Many metal forming parts cannot be manufactured without casting.

Nickel-based alloys have high strength and good oxidation resistance, corrosion resistance and high temperature resistance in the range of 650 to 1000°C. Nickel-based alloy is a common high-temperature resistance alloy.

As a precision casting process, the shell making is a very critical process during investment casting. The quality of the shell is directly related to the roughness and dimensional tolerance of the final casting. Therefore, it is an i...

Stainless steel is a commonly used alloy in precision investment casting. Because stainless steel has excellent properties such as corrosion resistance and oxidation resistance, stainless steel castings are also widely used in various...

Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an ex...

Sand casting takes advantage of sand's inherent compactability, refractory nature and recyclability to produce relatively inexpensive molds. Sand casting requires a relatively low investment and allows for quick tooling development ...

Solution heat treatment is generally used for stainless steel castings. Its main purpose is to dissolve carbides or other precipitated phases in the stainless steel in solid solution so as to obtain a supersaturated single-phase structur...
