The chemical composition of stainless steel can be divided into two broad categories: austenitic and ferritic. While CF8M and CF3M are part of the austenitic family, they also differ in their composition. The main component that sets them apart from each other is chromium content; CF8M contains 8-10% chromium, while CF3M contains 3-4%.

CF8M cast stainless steel open impeller for centrifugal pump by investment casting, CNC machining and dynamic balancing. CF8M is a cast austenitic stainless steel which covered by ASTM A351, ASTM A743 and ASTM A744 standard. CF8M equal to SS 316/F 316 and Chinese Standard 0Cr17Ni12Mo2. CF8M is a molybdenum bearing modification of CF8 …

CF8M is the designation in both the ACI and ASTM systems for this material. J92900 is the UNS number. It has a fairly high ductility and a moderately high thermal conductivity among cast austenitic stainless steels.

Abstract. This specification covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts. The steel shall be made by the …

Unlike CF8M and CF3M of ASTM A351, CF8C grade has option for stabilization treatment due to Nb present which forms carbides, between 870 and 900 °C after solution annealing in austenite matrix. This prevents depletion of chromium around grain boundary and prevents sensitization of steel. However, this stabilization treatment …

CF8, CF8M, CF3, CF3M are stainless steel castings in the American Standard ASTM A351 standard. CF8M is equivalent to China's ZG0Cr17Ni12Mo2. Corresponds to 316 stainless steel. CF8 is equivalent to China's ZG0Cr18Ni9. Corresponds to 304 stainless steel. CF3 is equivalent to 304L. CF3M is equivalent to 316L.

ASTM A351 CF8 is the equivalent investment cast alloy of AISI 304 stainless steel, which belongs to austenitic stainless steel that presents good strength and ductility. As the chemical composition of CF8 includes approximately 18% chromium and 8% nickel by weight, it is also known as 18/8 stainless steel.

It is covered by ASTM A351 and ASTM A743, and ASTM A744 standard. There is a little difference in chemical compostions as below: Standard: ASTM A351: ASTM A743 : ASTM A744 : Grade : CF8M: CF8M : CF8M: UNS: ... AISI 316 stainless steel and ASTM CF8M stainless steel are called austenitic Stainless steel. But grades 430 and CB-30 are called ...

Differences between CF8M and 304. One major difference between these two stainless steel alloys is their level of corrosion resistance; At the same time, both offer excellent protection from rusting, or corrosion on their own, cf8m offers superior corrosion resistance compared to 304 thanks to its higher molybdenum content.

316/316L STAINLESS VALVES. Valves are manufactured in ASTM A182 316/316L forgings and ASTM A351 CF8/CF3 castings. Trim components can also be in UNS S31600 and AISI-SAE 316/316L. Welded end valves can be in 316 but 316L is often preferred due to the lower carbon content which avoids inter granular corrosion in the as-welded state thereby ...

Conclusion. In summary, ASTM A351 CF8M stainless steel castings shows better corrosition resistance, while CF8 stainless steel castings have lower cost. The selection of these two alloys mainly …
