What is stainless steel?

Stainless steel is a type of low-carbon steel that is resistant to corrosion and rusting. It is made from iron, chromium, and other elements, such as nickel, carbon, molybdenum, and nitrogen. The chromium content in stainless steel is at least 10.5%, which creates a chromium oxide layer on the surface that protects the material from further oxidation.

Stainless steel has many properties, including corrosion resistance, durability, temperature resistance, recyclability, maintenance, modern appearance, high tensile strength, good ductility and high hardness. The stainless steel can be used in many different industries, such as automotive, aircraft, construction, marine, medical, food, etc.

Investment casting process for cast steel pipe fittings:

Investment casting is an industrial metal casting process based on lost-wax precision casting, generally used for producing complex-shaped metal components that require tighter tolerances, thinner walls and better surface finish than other sand cast parts. Baoding Guokun can produce various investment casting parts in low-carbon steel, mild steel, alloy steel, stainless steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

Two types of investment cast processes: Silica Sol process and the water glass process.

The Silica Sol investment casting process is used to cast complex high-quality parts with requirements of a very good surface finish and close dimensional tolerances. This process can range from a weight of just a few ounces to approximately 80 pounds. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations.

The water glass casting process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than the Silica Sol process, but does not have as good of surface finish or tolerances. The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings. This process may range in weight from several ounces to approximately 200 pounds.

First article layouts and spectrometer material certifications are provided with all first article samples.

Custom service: A variety of secondary operations can be performed on both types of investment castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.
