摘要
通过改善不锈钢的合金元素及热处理方式,为林产品干燥选材提供依据。以06Cr17Ni12Mo2不锈钢为基础,分别在其中添加微量Cu元素和Sn元素得到两种新的材料,对这三种材料进行不同退火温度下的热处理,分别对其组织、力学性能及耐蚀性进行分析研究。在微观组织方面,退火温度的升高会带来晶粒的长大,添加微量Cu元素也会使晶粒变大但添加微量Sn元素会使晶粒变小。在力学性能方面,添加铜元素对强度较小影响,但提高了延伸率,添加锡元素强度有所上升而延伸率变化不大。在耐蚀性方面,添加铜元素提高了耐蚀性,而添加锡元素同样也提高了耐蚀性但效果没有铜元素好。在06Cr17Ni12Mo2钢上添加Sn元素更符合林产品干燥设备用材的使用。
By added the alloy elements and improved heat treatment of stainless steel, to provide the basis for the drying of forest products drying equipment. Based on the 06Cr17Ni12Mo2 steel, we added Cu and Sn elements respectively to get two kinds of new materials, and then deal with them under different annealing temperature of heat treatment. The microstructure, mechanical properties and corrosion resistance were discussed. The results indicated that in terms of microstructure, an increasing annealing temperature will lead to grain growing up. Adding Cu element can make the grain size larger but also adding Sn element can make the grain size smaller. In terms of mechanical properties, adding Cu element had little influence on strength but improved the elongation, adding Sn element improved the strength but had little influence on elongation. In terms of corrosion resistance, adding Cu element improved the corrosion resistance and adding Sn element improved the corrosion resistance too but the effect was not better than Cu. This method which added Sn elements on 06Cr17Ni12Mo2 is more in line with the use of forest products drying equipment.
