Abstract

The chemical composition and production process of a new kind of enameling steel sheet used for heat-exchanger were introduced. The microstructure, mechanical property and hydrogen permeation resistance of the steel sheet were studied. The enameling adherence and pin-hole ratio of the enameled steel sheet were measured. The results show that the microstructure is ferrite with the grain size of grade 11 and quantities of linear MnS inclusions, grainy manganese-niobium composite oxides and small NbC precipitates are formed in the steel. The average value of hydrogen permeation resistance of the steel is 33 min·mm-2, the enameling adherence is evaluated as level A1and the number of the pin-hole defects in the enameled steel is less than 10 per square meter. Both mechanical property and enameling quality of the steel sheet meet the technical demand of heat-exchanger.
