Application of 314 Stainless Steel
Austenitic 314 stainless steel (UNS S31400, EN 1.4841, X15CrNiSi25-21) is a chromium-nickel-silicon alloy engineered for continuous high-temperature service. Compared with 310/310S, 314 contains elevated silicon and robust Cr–Ni content that together improve oxidation and scaling resistance and give better creep strength at elevated temperatures — making 314 a go-to material for...

Surface Treatments & Non-Stick Systems of Cast Aluminum Cookware
Cast aluminum cookware is widely favored in household and commercial kitchens due to its excellent thermal conductivity (120–150 W/(m·K)), lightweight properties (density 2.7 g/cm³), and good formability for complex shapes. However, pure cast aluminum has inherent drawbacks: poor corrosion resistance (prone to oxidation and pitting in acidic/alkaline environments), low...

Shell Mold Casting Process
1. Introduction Shell mold casting, a precision variant of sand casting, is a widely adopted metal casting process renowned for producing components with superior dimensional accuracy, fine surface finish, and consistent mechanical properties. At its core, shell mold casting uses thermosetting resin-coated sand to form thin, rigid mold shells (3–10 mm thick) around a heated metal...

Properties and Applications of CF8M Stainless Steel
Introduction CF8M stainless steel is a premium cast austenitic stainless steel defined by authoritative standards including ASTM A351, ASTM A743 and ASTM A744, serving as the cast equivalent of wrought AISI 316 stainless steel. Its core advantage lies in the addition of molybdenum, which endows it with superior pitting and crevice corrosion resistance compared to molybdenum-free cast...

Casting & Foundry Practice for Stainless Steel CF3M Castings
1. Executive summary CF3M is the low-carbon, molybdenum-containing cast austenitic stainless steel commonly specified where chloride-bearing fluids or marine exposure are present and where cast geometry (complex ports, thin ribs, integral bosses) is preferred. The low carbon minimizes carbide precipitation (sensitization) around grain boundaries, the molybdenum improves pitting resistance,...

Investment Casting Shell Systems
The shell system is the single most important variable that determines surface fidelity, thermal resistance, permeability/venting, vacuum compatibility and alloy suitability in investment casting. Three practical families are used in modern shops: Silica-sol (colloidal-silica) shells — the premium, high-fidelity route. Water-glass (sodium-silicate) shells — the...
