Evaluation of hot corrosion performance of 904L stainless steel through corrosion-enhanced erosion testing at elevated temperature (650 °C)
The hot corrosion-enhanced solid particle erosion behavior of super austenitic stainless steel 904L was investigated at 650 °C. Cyclic corrosion tests (25 hours in 5-hour cycles) employed a Na 2 SO 4 –NaCl (3:1 wt%) salt deposit of 4.0–4.5 mg cm −2 . Salt-coated specimens obeyed a parabolic rate law (k p = 1...
