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.

Baoding Guokun Investment casting process steps for 304 OEM casting parts:

No. Steps Details
1 Patterns Makings Creating a wax mold of the desired stainless steel pump impellers, and then adding sprues to the wax model to create a tree-like structure.
2 Shell Building Coating the wax pattern with a layer of fire-resistant paint, and then to be sprinkled with sand, so after a period of hardening, the surface will form a layer of fire-resistant thin shell. 
3 Dewaxing Removing the wax, the shell is placed into an oven, melting the wax so that it can run out of the shell.
4 Pouring Pouring the molten stainless steel into the shell, and waiting for solidification under room temperature.
5 Post treatment After cooling, knock the shell and cut the sprue gate by grinding machinery to achieve net shape impeller castings. Then shot blasting to move mill scales to assure the smooth casting surface.
6 Machining CNC Machining & Balancing
