Stainless steel casting, or stainless steel investment casting, is the lost wax investment casting process by pouring melton stainless steel into moulds for solidification,

thus to achieve a solid stainless steel component in desired shape.

Stainless steel casting is considered when both the properties of steel and corrosion resistance are required.

So like other cast steel alloys, stainless steel is widely used material for casting production. at present，

the most dimension precision stainless investment casting method is Silica Sol Casting, Dimensional tolerance control in ±0.1mm.

304 Stainless Steel Castings
304 stainless steel is the most common grade of stainless steel castings, largely due to its excellent corrosion resistance and value. It contains between 16 and 24 percent chromium and up to 35 percent nickel, as well as small amounts of carbon and manganese.

The most common form of 304 stainless steel is 18-8 stainless steel or 18/8 stainless steel, which contains 18 percent chromium and 8 percent nickel.

304 stainless steel has great advantages for casting: it is susceptible to corrosion from chloride solutions, or from saline environments like the coast. Chloride ions can create localized areas of corrosion, called “pitting,” which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.

304 stainless steel casting in Artisan Industry foundry has the price advantage and good anti-rust property due to its material. The 304 is a steel number for wrought steel, Cast 304 is equivalent to CF8 of the US, or 1.4308 of Germany. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for manufacturing of food processor, household appliances, lockset, kitchen and sanitary ware, door and window, medical apparatus, architectural ornament, etc. For your information, the 304 stainless steel casting after polishing has a brilliant appearance and decorative effect.

As the 304 stainless steel castings manufacturer and supplier in China, Artisan Industry foundry offers a broad range of custom services including precision machining for 304 stainless steel castings. We can make 304 stainless steel casting with close tolerances using solical sol investment casting process. Of course, we can also produce such stainless steel casting in other grades, such as 316 stainless steel casting, PH17-4 stainless steel casting, and more.

• Weights: a few grams to more than 50 pounds

• Surface: very smooth finish

• Tight tolerances

• Reliable process controls and repeatability

• Design and casting versatility

• Efficient production

• Affordable tooling

• Material variety

• Investment casting has significantly cheaper tooling and is a more cost-effective option for lower quantity production runs. Additional benefits include a larger alloy selection and the ability to cast larger pieces.

• Investment casting provides a better surface finish and allows for greater design flexibility including the ability to cast thinner walls, create tighter tolerances and create more intricate coring.

• Stainless Steel Investment casting can significantly reduce the cost and lower the production time per piece. This is accomplished by producing near net shape parts, while greatly reducing the amount of material waste. In some instances, multiple fabricated parts can be produced as a single casting.
