FV520B Precipitation Hardening Stainless Steel Plate for Large centrifugal compressor

FV520B Precipitation Hardening Stainless Steel Plate

Application area:

Large centrifugal compressor / Fan system

FV520b is a new type of martensitic precipitation hardening acid and heat-resistant stainless steel developed on the basis of the original FV520. The type steel precipitates ε - Cu, NBC, Mo2C, M7C3 and M23C6 in the aging process through strengthening elements such as Cu, Nb and Mo, which plays the largest strengthening effect

chemical composition:

FV520B Precipitation Hardening Stainless Steel Plate

The mechanical properties of FV520B steel such as strength, plasticity and toughness are particularly sensitive to the heat treatment process. The microstructure of FV520B stainless steel before and after solution treatment + adjustment + aging heat treatment is found.

After heat treatment, the lath martensite structure of FV520B steel is fine and uniform, which increases the number of grains, increases the grain boundary area, and the second phase particles uniformly distributed in the matrix, so that the solution + adjustment + aging treatment FV520B The tensile resistance and fatigue resistance of steel have been significantly improved

The strength of fv520b steel reaches the maximum value at 1050 ℃ solution treatment + 850 ℃ intermediate treatment + 470 ℃ aging.
