连续热处理过程中张力对超窄2Cr13带钢耐蚀性能的影响

Influence of tension on corrosion resistance of super narrow 2Cr13 steel strip during continuous heat treatment

通过对连续热处理过程中受到不同张力的超窄2Cr13带钢进行盐雾实验以及金相组织观察,探讨了超窄2Cr13带钢生产过程中张力对其耐腐蚀性能的影响。结果表明,当带钢所加载的张力不超过98 N(宽度减小率不超过1.8%)时,试样的耐腐蚀性能不会产生变化;当带钢所加载的张力大于98 N(宽度减小率超过1.8%)时,试样的耐腐蚀性能随着张力的增大而变差。

According to the salt mist test and observation on the microstructure of the super narrow 2 Cr13 steel strip during continuous heat treatment under different tension,the influence of the tension on the corrosion resistance of super narrow 2 Cr13 steel strip were discussed.The result shows that when the tension loaded on the steel strip no more than 98 N(the width reduce rate no more than 1.8%),the corrosion resistance of the sample does not change.When the tension loaded on the steel strip more than 98 N(the width reduce rate more than 1.8%),the corrosion resistance of the sample become weak as the tension raise.
