This paper was aimed at investigatiing the influence of post-weld heat treatmenton the mechanical properties of stainless steel overlaid joint and discussing the relaiionbetween the change in impact toughness and micro structure in the overlaid cladding.The base metal was Q-T treated Ni Cr-Mo-V high strength steel.In the inner surfaceof vessel two layers of clad metal were deposited by submerged arc weldingwith chromium-nickel stainless steel strip as the consumable electrode.The first layerwas 0Cr20Ni10 and the second layer was 00Cr20Ni10 stainless steel.A seriesof test specimens were taken from the overlaid cladding,bonding line and heataffected zone of welded pieces,which had been heat treated at 600,625,650and 680℃ for 15,30,50 and 100 hours.The results obtained are as follows:(1)The post-weld heat treatment temperature shouldnt be over 650℃ for Q-Ttreated Ni-Cr-Mo-V high strength steel.(2)All side bending specimens are freeof cracks after bending,but the ductility in the bonding area decreases with increasedtime of post-weld heat treatment and its temperature.Ductility loss is associatedwith the width of diffusion of carbon from base metal to the overlaid cladding.(3)The toughness of the overlaid cladding decreases with increased time of post-weld heat treatment and its temperature.The decrease of toughness also depends onferrite content and carbon content.(4)0Cr20Ni10 low carbon stainless steelcladding is less susceptible to embrittlement than 0Cr20Ni10Nb cladding.(5)The embrittlement of 00Cr20Ni10 extra low carbon overlaid cladding after post-weldheat treatment is due to the Cr23C6 precipited along the ferrite boundries as wellas the formation of a very small amount of (?) phase.

本文研究了焊后热处理对不锈钢堆焊接头机械性能的影响,并探讨了堆焊层韧性和显微组织变化之间的关系。母材是调质处理的Ni-Cr-Mo-V 高强钢。容器内壁采用双层带极埋弧堆焊工艺,过渡层和不锈层分别为0 Cr20Ni10和00 Cr20Ni10不锈钢。试件取自堆焊层、接合区和热影响区,其焊后热处理工艺是600、625、650和680℃并均分别保温15、30、sO和100小时。试验结果如下:(1)对调质处理的Ni-Cr-Mo-V 高强钢,焊后热处理温度不得高于650℃。(2)冷弯后所有侧弯试件都未出现裂纹,但接合区的延性却随加热温度的提高和保温时间的延长而减少。延性减少与接合区中碳扩散层宽度有关.(3)堆焊层韧性随加热温度的提高和保温时间的延长而减少。它也与堆焊层的焊态铁素体含量和含碳量有关.(4)0Cr20Ni10不锈钢堆焊层的抗脆化性能高于0 Cr20Ni10Nb 堆焊层.(5)对00Cr20Ni10超低碳堆焊层热处理后产生脆化的原因是沿铁素体相析出Cr23C6和形成极少量的σ相.

Silicon content severly influences the behavior of intercrystalline corrosion of the extra low carbon, Cr-Ni austenite stainless steels in strong oxidizing concentrated nitric acid. In sensitized high purity stainless steel containing Si less than 0.1% the intergranular corrosion susceptibility decreases while in non-sensitized high Si stainless steel containing Si more than 2% the intergranular corrosion susceptibility decreases. The modelling of correlation between Si content and corrosion rate of extra low carbon, Cr-Ni austenite stainless steels has been identified in 98% smoke nitric acid. Based on the distribution profile of test data, the following exponential model has been selected:Y=B1+B2exp-[B3(X-B4)2]where Y is corrosion rate (g/m2.h); X is Si content in steel (%); B1, B2, B3, B4 is model parameters. These parameters were estimated by simplex searching method.

超低碳铬镍奥氏体不锈钢中的硅含量,对钢在强氧化性介质浓硝酸中晶间腐蚀行为,有着重要的影响,硅含量小于0.1%的高纯不锈钢,可降低敏化态晶间腐蚀,而硅含量大于2%的高硅不锈钢则可以降低非敏化态晶间腐蚀。 本文采用电子计算机对超低碳铬镍奥氏体不锈钢在98%发烟硝酸中腐蚀率和钢中硅含量关系的数学模型,进行了辨识。根据试验数据散点图形状,选定指数模型: Y=B_1+B_2exp〔-B_3(X—B_4)~2〕,其中Y为腐蚀率(g/m~2·h),X为钢中硅含量(%),B_(19) B_(29) B_(39) B_4为模型参数。模型参数采用非线性回归的单纯形搜索法进行估计。

Phisical properties, machanical propcrties, cold formability and corrosion resistance of typicalCr-Ni Austcnitic stainless steels are presented. It is shown that the corrosion resistance and coldformability of extra-low carbon Cr-Ni Austenitic stainless steels (304L, 316L) are markedly superior to those of Ti-stabilizing Cr-Ni Austenitic stainless steels (321, 316Ti).

The effects of main alloy elements in Cr-Ni Austenitic stainless steels are rsummarized in thispaper. Phisical properties, machanical propcrties, cold formability and corrosion resistance of typicalCr-Ni Austcnitic stainless steels are presented. It is shown that the corrosion resistance and coldformability of extra-low carbon Cr-Ni Austenitic stainless steels (304L, 316L) are markedly superior to those of Ti-stabilizing Cr-Ni Austenitic stainless steels (321, 316Ti). Therefore, it is suggested to replace the Ti-stabilizing Cr-Ni stainless steel(321) with extra-low carbon Cr-Ni Austenitic(304L) in corrosion service.

本文汇集了主要合金元素在Cr-Ni奥氏体不锈钢的作用、扼要介绍了典型Cr-Ni不锈钢的物理、力学、冷成型和耐蚀性。事实上,超低碳奥氏体不锈钢00Cr18Ni10和00Cr18Ni14Mo2(304L和316L)的耐蚀性和冷成型性能显著优于Ti稳定化的奥氏体不锈钢。鉴于这种状况,建议在腐蚀环境中,应该使用超低碳Cr-Ni奥氏体不锈钢(304L)代替目前广泛使用的Ti稳定化不锈钢(321)。
