Product Description

Products Description

Like other cast steel alloys, stainless steel is a common material for casting production. When the properties of steel and corrosion resistance are required for products, Stainless steel casting is the best choice.
Stainless steel casting, also called stainless steel investment casting, refers to the formation of ceramics around a wax pattern to form a shell for casting stainless steel. Once wax patterns are created, they are melted into the gate system, immersed in slurry and sand to form a layered shell, and then replaced by molten stainless steel.

How are Stainless Steel Castings Made?

Stainless steel casting involves creating an original wax model, building the image with plaster and successive layers until a strong shell surrounds the model. After melting the wax, pour the molten stainless steel into the mold to create a perfect replica of the original wax pattern. Stainless steel casting provides economical undercutting, high resolution, sophisticated detail, and a smooth surface finish compared to machining separations.
In most cases, stainless steel casting is the only way the part can be made economically.

Common Material Grades of Stainless Steel Casting

• 304-The most widely used austenite steel, may be referred to as A2 stainless.
• 304L-This grade has slightly lower mechanical properties than the standard 304 grade, but is still widely used in casting for its versatility.
• 316--The second most common austenite steel, also referred to as A4 stainless. SS316 is used primarily for its increased resistance to corrosion.
• 316L-Lower carbon content than 316 stainless steel, which reduces the sensitization effect caused by the high temperatures involved in welding. Besides, it shows better resistance to stress-corrosion cracking.
• 17-4 PH -Most common precipitation-hardening martensitic stainless steel, which uses about 17% chromium and 4% nickel.
• 2205 Duplex-Used for its good mechanical properties and excellent corrosion resistance properties.

Common Cast Stainless Steel Grades,Features, Applications

Grades	Features	Applications
304	Austenitic stainless steel with Ni content more than 8%, food-grade alloy. can be used to cast stainless steel components for both household and commercial applications. Widely used stainless steel casting material. 304 stainless steel castings can be used in environments where the air is less corrosive.	Medical, food industry, chemical industry, mechanical equipment, pipe industry, automotive industry, etc.
316	Also austenitic stainless steel with Ni content of more than 10%. For their higher Ni content, 316 stainless steel castings have better corrosion resistance than 304 stainless steel castings. Such stainless steel castings better suit the marine environment with relatively harsh air conditions or chemical materials that need to be contacted.	Fire fighting, auto parts, marine hardwares, chemical, pipeline, construction, decoration, food industry, etc.
304L / 316L	The mechanical properties are close to those of 304 and 316 materials. L represents lower carbon content, which makes the material more ductile, has good welding performance, and has more reliable corrosion resistance. The price is higher than that of materials of the same grade.	Food, chemical, medical, plumbing, etc.
410 & 416	Series 400 belongs to martensitic stainless steel, which is characterized by high strength, good processing performance, and high heat treatment hardness, and does not contain Ni, so the corrosion resistance is weak.	Auto parts, tools, knives, etc.
17-4 PH	17-4 belongs to martensitic stainless steel with a Ni content of 3%-5% and good corrosion resistance. It has the highest strength in the stainless steel series and is usually used for products and components that are not prone to deformation.	Medical, mechanical components, machine tools, turbine blades, etc.
2205	Duplex stainless steel 2205 is composite stainless steel consisting of 22% chromium, 2.5% molybdenum, and 4.5% nickel-nitrogen. It has high strength, good impact toughness, and good overall and local resistance to stress corrosion.	Sporting, pump & valve industry, etc.

Stainless Steel Castings Application

Stainless steel has unique physical properties. Such as extremely high resistance to heat, abrasion, and corrosion. So it can be served for a different range of industries, especially in some severe environments. Here are the main usages of stainless steel casting:

1-Food processing and machinery:

A large amount of stainless steel is also used in food production and storage. Almost all food processing equipment is made of stainless steel. The most common grades are 304 and 316. 304 is basically the main level, while 316 is used in the harsher environment. Stainless steel castings are widely used in food machinery applications due to their rust-preventing capabilities and the most flexible manufacturing processes for complex-shaped parts. Typical food machinery parts made with stainless steel casting processes are metal grinder parts, coffee machine parts, etc. An important reason for using stainless steel is not the corrosive nature of the food itself, but the use of stainless steel for faster and more efficient cleaning. The advantage is that it does not expose the food to any taste.

2-Kitchenware and Cutlery in kitchen

The most commonly used stainless steel may be used for tableware and Cutlery in the kitchen. For example, Grade 410 and 420 can be hardened and tempered, allowing the blade to use sharp edges to produce tools. Grade 304 (18/8 stainless steel, 18% chromium 8% nickel), more ductile 18/8 stainless steel is easier to a machine. So it is more suitable for objects that need many molding, polishing, and grinding processes for spoons and forks, and other tableware.

3-Marine:

Stainless steel casting is used in marine applications which require parts that are strong with extremely high resistance to heat, abrasion, and corrosion. Our stainless steel alloys for recreational, commercial marine components. Stainless steel marine castings can be polished to a mirror finish for maximum corrosion and abrasion resistance. New marine grade stainless steel investment castings for marine application could be supplied electronically polished and machined from our company, saving our customers 40% on their current cost.

4-Medical Equipment:

Stainless steel casting can produce a wide range of components and medical implants for medical instrument manufacturers. We work with many stainless steel materials, including stainless steel 304(L), stainless steel 316(L), and more, to create custom parts that meet the tight tolerances and dimensional precision required by the medical application.

A great deal of medical equipment - such as orthopedic beds, cabinets, and examination machines - is made as standard from stainless because of its hygienic and easy-clean qualities. What we can offer more Stainless steel cast parts included in surgical tools, Implantable components, operating tables & other operating room equipment, stretchers, wheelchairs, and similar products, stabilizing devices.

5-Pipe Fittings:

Stainless steel pipe fittings come in a variety of shapes, so the installation process is convenient. Because of the high performance and durability of stainless steel fittings, stainless steel fittings are widely used for piping construction and installation. Stainless steel pipe fittings are available in stainless steel flanges, stainless steel heads,elbow, tee, bushing, close nipples, etc. Our machining capability can meet any machining requirement like threads. When purchasing pipe fittings, considering the application, these pipe fittings are normally made of stainless steel 316, which is higher strength and more corrosion resistant than stainless steel 304.
 

6-Pump and Components:

Stainless steel casting is one of the most widely used techniques for valve and pump components. Common valve and pump components made from stainless steel casting include valve body, valve disc, valve bonnet, valve gland, pump body, pump impeller, etc. Since its complicated design of valve and pump components, stainless steel casting can produce any complex shape. Valve and pump components from stainless steel casting are durable enough for severe service applications. So stainless steel casting is a cost-efficient way and a popular selection for pump and valve applications.

7-Building and Construction

Modern buildings use more stainless steel for cladding, roofing, and facades. It has low maintenance cost and anti-vandal characteristics and aesthetics. Especially the public construction market. Stainless steel reinforcing bar, although initially expensive, is proving to have very good life cycle costing characteristics.

Other usages of Stainless Steel Castings are Door & Windows, Bathroom & Toilet fittings, etc.
