Product description

CF8M, as a classic austenitic stainless steel (equivalent to 316), its outstanding performance stems from a scientific composition combination. 18% chromium is the foundation of corrosion resistance, which can quickly form a dense Cr?O? oxide film on the material surface, effectively resisting the erosion of chemical media and acid and alkali solutions. 8% nickel element builds a stable austenite lattice, endowing the material with excellent toughness and ductility. Even in an extremely cold environment of -196 ℃, it can still maintain good mechanical properties, avoid low-temperature brittle fracture, and at the same time support structural stability under high-temperature working conditions.

The 2% to 3% molybdenum element is its core advantage, which can significantly enhance the resistance to pitting and crevice corrosion. Especially in environments containing chloride ions, the pitting equivalent value (PREN) is greatly increased, and the corrosion rate can be controlled to less than one-third of that of ordinary austenitic stainless steel, making it perfectly suitable for harsh media such as seawater and salt water. This material performs reliably within a wide temperature range of -196 ℃ to 800℃. It has good oxidation resistance at high temperatures and its mechanical properties do not decline at low temperatures. In addition, its excellent casting performance and machinability make it the preferred choice for fields with high requirements for corrosion resistance and temperature adaptability, laying a solid material foundation for the long-term stable operation of equipment.
