The foundation design of the astm a297 grade hf as cast austenitic stainless steel should meet the requirements of foundation stability and deformation, that is, the astm a297 grade hf as cast austenitic stainless steel foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the astm a297 grade hf as cast austenitic stainless steel and cause distortion and deformation of the tank wall and bottom plate.

The duplex stainless steel alloys have a mixed microstructure of austenite and ferrite, the optimal ratio is 50/50, however in actual duplex stainless steel castings the ratio may be 40/60 or 60/40. The cast duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated, cast duplex stainless steels have roughly twice the yield strength compared to austenitic stainless steel All Metals Standards - ASTM InternationalA664-15: Standard Practice for Identification of Standard Electrical Steel Grades in ASTM Specifications.
