A SORT OF SENSITIVE ERODING REAGENT ON SPOT ERODING OF MARTENSITE STAINLESS STEEL

Spot eroding is easily observed when martensite stainless steel is eroded by solution of HF,HNO3 and H2O,with macula shape. Hence the sort of eroding reagent can be applied to inspection of spot eroding tendency on martensite stainless steel. Operation and statistic for years shows that spot eroding resistance of refining steel is obviously better than that of conventional steel,so the sort of eroding reagent can be applied to assessing of quality of martensite stainless steel.
