304 and 316 stainless steel butterrfly valve, known as CF8 and CF8M respectively. The compositional makeup of these two alloys are similar: chromium and nickel contents. CF8M contains 2% to 3% molybdenum that CF8 does not have.
CF8M 316 Stainless Steel
The corrosion resistant alloy Type 316 is molybdenum steel possessing improved resistance to pitting for solutions containing chlorides and other halides. In addition it provides excellent elevated temperature, tensile, creep, stress and rupture strengths.
CF8 304 Stainless Steel
General purpose corrosion resistant alloy. Has low carbon content and is non-magnetic. May be susceptible to chloride stress corrosion cracking.
