Mechanical properties, wear and corrosion of boronized N80 tube steel
The effect of boronizing on mechanical properties, wear and corrosion of boronized N80 tube steel is studied. A dual-phase boride layer consisting of FeB and F₂B phases was formed on the surface of steel substrate in a hardness range of 1220 to1340 HV. A set-up to use less boriding agent and acceler...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The effect of boronizing on mechanical properties, wear and corrosion of boronized N80 tube steel is studied. A dual-phase boride layer consisting of FeB and F₂B phases was formed on the surface of steel substrate in a hardness range of 1220 to1340 HV. A set-up to use less boriding agent and accelerate the pipe’s cooling process was designed. In order to meet the tensile properties of N80 steel required by API SPEC 5L, four cooling methods were employed. The fan-cooling with a graphite bar inside the boriding agent resulted in the highest mechanical properties, in accordance with the mechanical properties of API SPEC 5L. The boronized N80 steel showed a high wear resistance under dry sliding condition and excellent corrosion resistance in as-received oilfield water from Jilin oil field, Northeast China. |
