钢带试样位向及拉伸性能的探讨

Discussion of tensile property and test piece location

从碳素结构钢热轧钢带各向异性的事实出发 ,阐述不同试样位向导致同一钢带不同的拉伸性能 ,因而影响钢带合格与否的判定。在全面考虑钢带和焊管标准的基础上 ,提出解决钢带判定的两种方法。同时 ,还对标准中存在的缺点作了说明 ,提出改进意见 ,供标准修订时参考。

In anisotropy fact,describe different test piece location,produce different tensile property,effect qualification test of steel strip.Give qualitative two means to take account of standard for steel strip and welded steel pipe.And modify defect of standard.
