Description

Stainless steel Explosion-proof light housing

The stainless steel 316 lost wax casting parts produced by Guokun, usually servce different industries, such as pump impeller, pump housing, pump casing, valve, marine, agriculture, aircraft, food, medical machinery, motor, etc.

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.

The common stainless steel grades

stainless steel alloys
Grades	Chemical Composition				Mechanical Properties
Grades	C	Cr	Ni	Mo	Tensile Strength MPa	Yield strength Mpa	Elongation %
304	≤0.08	18 ~ 20	8 ~ 11	–	≥520	≥205	≥45
304L	≤0.03	18 ~ 20	8 ~ 12	–	≥480	≥175	≥45
316	≤0.08	16 ~ 18	10 ~ 14	2 ~ 3	≥520	≥205	≥45
316L	≤0.03	16 ~ 18	10 ~ 14	2 ~ 3	≥480	≥175	≥45
410	≤0.12	11.5 ~ 13.5	≤0.75	–	≥440	≥205	≥20
430	≤0.12	16 ~ 18	≤0.75	–	≥450	≥205	≥22

The most common stainless steel alloy is austenitic stainless steel, particularly Grade 304 and Grade 316, which is a mixture primarily composed of Cr and Ni, offering good corrosion resistance and excellent formability, making them widely used in various applications.

Baoding Guokun Investment casting process steps for 316 stainless steel Explosion-proof light housing 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
