摘　　要：对比分析了美国奥利根(OREGON)、德国司迪尔(STIHL)和国产伐木锯链的钢材化学成分、显微组织和性能。选用我国低合金工具钢6CrN iMoVNb作为锯链零件材料进行热处理工艺试验。结果表明,锯链钢经920℃加热、280℃等温淬火后强度高,塑韧性好,综合力学性能最佳,整体性能达到国外同类产品水平。Based on a comparison of the chain saw steels that made by the U.S.OREGON,the German STIHL and by a domestic manufacturer the effect of chemical composition and heat treatment on microstructure and mechanical properties of gomestic steel 6CrNiMoVNb was studied.The results show that after 920 ℃ heated and isothermal hardening at 280 ℃,superior ductility and mechanical properties can be obtained at the level of their counterparts made by the foreign manufactures.
