Stainless Steel is used for investment castings that require high resistance to corrosion and wear in safety-critical applications for defense, oil and gas, medical and other commercial industries. Stainless steel is a group of ferrous alloys that all contain chromium – the key ingredient for superior corrosion resistance. There are many grades of stainless steel with varying alloy composition and physical characteristics. All stainless steels contain at least 10.5 percent chromium but may contain significantly more depending on the application. Higher chromium content results in increased corrosion resistance. Additional alloying ingredients include molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous and selenium.
CFS Foundry pours more than 50 stainless steel alloys, and we commonly provide custom alloys with specific material chemistry and mechanical specifications. In the investment casting industry for more than 95 years, we are experts in providing engineered stainless steel solutions that are second to none.
CFS’ engineers are ready to assist our customers in selecting the stainless steel alloy best suited to your specific application. By working with our customers’ design teams, we deliver custom solutions and turn concepts into superior stainless steel investment cast products. From the beginning, we’ re involved in engineering for manufacturability which helps avoid problems and reduce cost.
Meeting our customers’ growing demand for high-quality stainless steel investment castings, CFS’ unique investment casting process allows us to manufacture large stainless steel investment castings up to 25 inches or 64 cm and 150 pounds or 68 kg. CFS Foundry has made the commitment to invest in new capabilities that add value to its products and customers. Today, our advanced technologies include CNC machining equipment, CAD workstations, welding and assembly.
WE SPECIALIZE IN HIGH-STRENGTH STAINLESS STEEL
In addition to 304, 316 stainless steel alloys, CFS pours other stainless steels, such as 17-4ph, 2205 duplex, 2207 duplex stainless steel, etc. Our Customers turn to CFS to meet premium mechanical properties through a combination of strict process controls and secondary thermal treatment parameters in alloys such as 17-4 PH Stainless Steel.
WE RECOGNIZE EACH CUSTOMER HAS UNIQUE REQUIREMENTS.
Stainless Steel Investment Castings – Our melt technicians are capable of custom mixing alloys as needed to produce a final metallurgy that is certified to meet individual customer requirements. Every heat is spectrographically tested to ensure the correct chemistry and mechanical properties are verified by in-house testing of separately cast tensile specimens. Metallurgical quality and integrity are ensured by archiving a small metal sample of each heat for seven to ten years to assure our customers of the metal quality and address any technical inquiries that may arise years after castings have been produced and shipped.
The CFS’ investment casting process produces complex high-precision components with greater dimensional accuracy, higher consistency and better surface finish than other casting methods. It is often the only way a part can be manufactured economically. We are experts at converting expensive multi-piece fabrications into one-piece castings significantly reducing cost and lead-times.
All components are manufactured for internal strength and integrity. With the precision lost-wax investment casting process, we can produce parts with strict tolerance requirements. CFS stainless steel foundry uses Solidification Modeling software to predict the outcome of a casting’s internal quality level before a part is ever made, significantly improving time-to-market and reducing development costs due to “trial and error” methods of process development.
