Dandong Dawang Steel Castings is a leading stainless steel company in china. We can offer a wide selection of stainless steel castings service. The most common alloy types we process are listed below. Besides, we can pour other melt alloys according to your requirement.

304/304L stainless steel casting:

Type alloy 304 is the most versatile alloy in the stainless steel series, and is ideal for a wide variety of household and commercial applications. Alloy 304 has excellent corrosion resistance, and is easy to process and shaped.It can be applied to various household and commercial applications, include: Kitchen workbenches, sinks, chemical containers, food processing equipment, automotive and aerospace applications, construction materials, architectural decoration and modeling, etc. (304L alloy is very similar to 304 alloy, the difference is that the maximum carbon content of 304 alloy is 0.08%, while 304L is 0.03%. This “L” can be understood as low carbon.)

316/316L stainless steel casting

Compared with 304 alloy, the molybdenum in 316 alloy 316 makes it have higher corrosion resistance. 316 can resist atmospheric corrosion and has excellent resistance to inter-granular corrosion under welding conditions. At high temperature, alloy 316 has higher creep and tensile strength. It is commonly used in the paper industry, chemical and textile processing equipment, furnace parts, etc.

410 stainless steel casting

Alloy 410 is a chromium martensitic stainless steel that can be heated to obtain a wide range of mechanical properties. Alloy 410 has high strength, hardness and good corrosion resistance. It is easy to extend and be formed. In addition, in all cases it is magnetic. It is commonly used in cutlery, petroleum refining, petrochemical processing, and marine environments, etc.

416 stainless steel casting

Alloy 416 series is high-chromium martensitic free-machining stainless steel. It has high strength and is easy to process. Type 416 alloy can be applied to axles, gears, valves, and lead screws etc. It is not recommended to apply to containers filled with gas or liquid under high pressure.

17-4 stainless steel casting

Alloy 17-4 is an age-hardening martensitic stainless steel that combines high strength and corrosion resistance. Hardening can be achieved after a simple low-temperature treatment. It still has high tensile strength, hardness, oxidation resistance and good creep stress rupture performance at high temperature. Compared with traditional martensitic stainless steel, alloy 17-4 is more weldable. All that properties make it widely used in oil, natural gas, aerospace and other fields.

Stainless Steel Casting Process

Stainless Steel Investment Casting Process

Each process of our production is executed in strict accordance with the Standard Operation Procedure (SOP). The main stainless steel investment casting process is as the following: Pouring simulation, Mold development, Raw material inspection, Wax pattern, Shell preparation, Metal pouring, Cleaning and Heat treatment, Inspection, Warehouse packaging, and Shipping. Seeking affordable stainless steel investment casting manufacturers or professional stainless steel casting suppliers? Do not hesitate to contact us.

Mold Development

The technical department develops the mold, and the quality department uses the three coordinates to carry out the dimensional inspection.

Wax Pattern

The workshop uses automatic waxing machines to set the waxing pressure, holding time, etc. and to produce high quality was patterns.

Shell Preparation

The workshop has 4 automatic production lines, able to produce 1800 sets of shells. We use hygrothermograph, aerometer, and PH to monitor humidity, temperature, and concentration of liquor aluminum chloride.

Metal Pouring

4 sets of 500KG furnaces are in production, and 3 sets of 500KG spare furnaces are ready when capacity increases. The operators conduct rigorous tests to fulfill material requirements.

Clean And Heat Treat

The workshop is fully equipped with 8 heat treatment furnaces, 3 quenching furnaces, 1 central shot blasting machine and 11 large shot blasting machines.

Inspection

All blank dimensions are checked using a CMM. We have rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company’s quality department has certified employees to do UT, PT, MT testing.

Stainless Steel Casting Process

Stainless Steel Sand Casting Process

Each process of our production is executed in strict accordance with the Standard Operation Procedure (SOP). The main process is as the following: Pouring simulation, Mold development, Raw material inspection, Modeling (Core-Making), Melting, Metal pouring, Cleaning and Heat treatment, Inspection, Warehouse packaging, and Shipping.

Mold Development

Design and produce molds according to the requirements of the drawings. Generally, wood molds can be used for single-piece production, plastic molds and metal molds are made for mass production, and templates can be made for mass castings. Our mold is mainly made of aluminum.

Modeling (Core-Making)

Includes modeling (forming the cavity of the casting with molding sand), core-making (forming the inner shape of the casting), and mold matching (putting the core into the cavity and closing the upper and lower flasks). Modeling is a key process in casting.

Melting

According to the required metal composition, the chemical composition is matched, and the appropriate melting furnace is selected to melt the alloy material to form a qualified liquid metal liquid (including qualified composition and qualified temperature)

Metal Pouring

Pour qualified molten metal into the sand box equipped with the mold. The pouring stage has high safety requirement, and we have rigorous process control to protect the safety of our employees.

Clean And Heat Treat

After the molten metal is poured and solidified, the molding sand is removed, and the gate and other attachments are knocked out to form the required casting.

Inspection

All blank dimensions are checked using a CMM. We have rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company’s quality department has certified employees to do UT, PT, MT testing.

Questions About Stainless Steel Casting Service

What Kind Of Casting Process You Can Do On Stainless Steel Parts?

Lost wax casting (Colloidal and Composite) , Sand casting.

As the leader stainless steel castings manufacturer in China, we are always trying to provide efficient and high-quality casting process.

How About The Price Of Your Stainless Steel Products?

As one of the best stainless steel castings manufacturers and professional stainless steel suppliers in China, we provide a reasonable price for our customers.

The basic raw casting price start from 5 USD/KG.

Are There Any Discounts On Stainless Steel Products?

Yes. As the leader stainless steel castings manufacturer in China, we have discounts for our customers when they purchase an amount of casting parts.

About stainless steel casting parts: when the total weight (1 kind) reach 10 tons or quantity reach 10,000 pieces, return the mold fee.

What's The Difference Between 304 And 304L Stainless Steel?

The main difference is the carbon content. 304 is qualified if the carbon content is below 0.08%, while 304L is qualified below 0.03%. The more popular carbon content means the quality. The lower the carbon content, the better the corrosion resistance of the material. Most stainless steel castings manufacturers can provide different types according to the customers’ requirements.
