304 Stainless Steel Investment Castings
Milwaukee Precision Casting, Inc. is experienced in pouring 304 stainless steel casts for applications such as food processing equipment, medical devices, and butterfly valves. 304 cast parts refers to components poured and cast from 304 stainless steel. 304 ss casting is widely known and accepted as being the standard for cleanliness, corrosion resistance, and weldability in the food industry, amongst others.
The 304 casting grade of stainless steel is soft and much easier to straighten than 316 or 17-4. It is comprised of a chromium-nickel content and can also be known as an “18-8” stainless steel since it is approximately 18% chromium and 8% nickel. It has the ability to be machined in the “as-cast” state and is austenitic stainless steel, meaning it is nonmagnetic, highly corrosion resistant, and can’t be hardened by heat treatment.
SS 304 Chemical Composition
304L Stainless Steel Castings
304L stainless steel is a variation of 304 stainless steel with higher nickel and lower carbon content. This forms a stainless steel casting with lower overall mechanical properties but higher corrosion resistance. As a result, the “L” in 304L is typically interpreted as “low carbon.” Milwaukee Precision Casting, Inc. can cast 304, 304L, and all other grades of stainless steel depending on your needs.
