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...
