Casting is a process in which a molten metal liquid is poured into a mold and cooled to solidify to obtain a desired shape and performance.

Casting is a common manufacturing method, with low manufacturing cost and high process flexibility. It can obtain complex shapes and large castings, and it occupies a large proportion in mechanical manufacturing, such as machine tools account for 60-80%, cars account for 25%, and tractors account for 50 to 60%.

Due to the current demands for casting quality, casting precision, casting cost and casting automation, casting technology is developing in the direction of precision, large-scale, high quality, automation and cleanliness.

The main processes of casting include: metal melting, model making, casting solidification and demoulding cleaning. The main materials used for casting are cast steel, cast iron, cast non-ferrous alloys (copper, aluminum, zinc, lead, etc.).

Stainless Steel Casting Material Information

Material grade  Application
304 Housings, bodies. SS304 is widely used in medical, plumbing, watering, mining and petrochemical industries as the standard for cleanliness as well as corrosion resistance.
304L/316L Similar to other 300 series steel, low carbon makes it softer but more corrosion resistant. Ideal industries are such as food & dairy, medical and petrochemical.
316 Housings, gears, plates. Superior corrosion resistance of SS316 makes it ideal for many applications including automotive, food & diary and petrochemical environments.
410 & 416 Housings, bushings, handles, brackets. 400 series steels are high strength and very machinable. They will tend to break rather than bend under intense pressure. Ideal industries are automotive, food & dairy and various machine tools.
