Stainless Steel Casting

Stainless steel casting is a metal working process to produce custom stainless steel parts. It works by pouring Melton stainless steel into molds for solidification, thus to achieve a solid stainless steel component in a desired shape.

Compared with other processes, stainless steel casting can create complex components with fine detail and good dimensional accuracy, which reduces or eliminates post machining operation. It is also a great alternative to welding fabrication process, as several stainless steel parts can be cast in one piece, which saves the time and cost for additional welding or assembling.

Stainless steel casting is considered where both the properties of steel and corrosion resistance are required. So like other cast steel alloys, stainless steel is one of the commonly used materials in casting production.


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.
3A, 4A, 5A, 6A...ETC.

Stainless Steel Casting Applications

For the unique physical properties of stainless steel, Stainless steel castings are served for a wide range of industries, especially those in severe environments. Below are the main applications of stainless steel casting:

  • Food Machinery
  • Valve & Pump Components
  • Marine Application
  • Pipe Fittings
  • Medical Parts,

Almost all the food processing equipment’s are made in stainless steel due to its rust prevention capability. Such food processing equipment’s are normally assembled by many stainless steel components. There are several processing processes to produce these stainless steel components, such as casting, forging, welding, machining from plate, etc. Among them, casting is the most flexible manufacturing process to produce complex shaped components for food processing machinery. So stainless steel casting is widely used for food machinery application! Typical food machinery components made in stainless steel casting process are: metal grinder components, coffee machine components, etc.


Other Applications of Stainless Steel Castings are: Sculpture parts, Bathroom & Toilet fittings, Door & Windows, etc.
