Stick welding of CF8M can be carried out using E316-15/ E316-16 type stick welding electrode.Į316-15 or E316-16 or E316-17, any of these welding rods can be used for welding applications. A high heat input can create issue of sensitization in the material which can impact its corrosion resistance properties. Welding shall be carried out using stringer beads and low heat input. It is having good weldability and can be easily welded with other stainless steel grades or carbon steel if required. SS316 CF8M WeldingĬF8M material can be welded using stick welding, TIG Welding or MIG Welding. Comparison of chemical composition of Cf8M and SS316 are given in the below table. The equivalent material of CF8M is SS316 material and not SS316L which has low carbon content. The Mechanical Properties of CF8M material are given in the below table: Tensile Strength 70 Ksi (485 MPa) minimum Yield Strength 30 Ksi (205 MPa) minimum Elongation 30% minimum Hardness 146-212 HB CF8M Mechanical Properties CF8M equivalent material CF8M Tensile Strength is 70 Ksi Minimum, Yield Strength is 30 Ksi & 30% elongation. Chromium (Cr) 18- 21 Nickel (Ni) 9.0 -12 Molybdenum (Mo) 2.0 -3.0 Chemical Composition of CF8M Casting Material CF8M Mechanical PropertiesĬF8M mechanical properties are important to consider when selecting a material for use in corrosive environments. The main chemical composition of CF8M material are listed in below Table: Element Weight % Carbon (C) 0.08 Max. It was specifically designed to provide superior corrosion resistance in harsh environments. It offers excellent resistance to both corrosion and heat. The main material specifications for CF8M Materials are:ĬF8M is a material composed of chromium, nickel and molybdenum. The CF8M material specification covers the chemical and mechanical requirements for this grade of stainless steel. It has excellent weldability and formability, making it a popular choice for many applications. CF8M Material SpecificationĬF8M is a versatile austenitic stainless steel that offers good corrosion resistance and strength. This alloy is used in applications such as values, fittings, process piping flanges, and structural members in the chemical industry. CF8M is usually used for service temperature up to 1500 Degree Fahrenheit.ĬF8M has good strength and toughness at elevated temperatures. It has excellent resistance to chlorides and other chemical environments.ĬF8M material is a non-hardenable alloy as it is an austenitic grade that can not be hardened by heat treatment. CF8M is a chromium-nickel-molybdenum alloy with high resistance to oxidation and pitting corrosion.
