Abstract

In this study, 125 ksi-grade oil casing steels with three chromium and two manganese contents were investigated through orthogonal experiments, and the resulting sulphide stress cracking (SSC) behaviours were analysed using the NACE-A method. The impact of manganese and chromium on the SSC performance was examined through a series of experiments involving microstructural assessments and hydrogen permeation tests. Limiting the chromium and manganese content proved to be pivotal in reducing the quantity of reversible hydrogen traps and Σ3 grain boundaries. Therefore, the proportion of manganese sulphide (MnS) precipitation was reduced, ultimately improving the resistance of the material to SSC.

锰、铬对125ksi级石油管件用高强度低合金钢硫化物应力开裂的影响

采用正交试验研究了含3铬2锰的125 ksi级石油套管钢，并用NACE-A方法对其硫化物应力开裂（SSC）行为进行了分析。通过一系列的实验，包括微观结构评估和氢渗透测试，研究了锰和铬对SSC性能的影响。限制铬和锰的含量被证明是减少可逆氢阱和Σ3晶界数量的关键。因此，降低了硫化锰（MnS）的析出比例，最终提高了材料的抗SSC性能。
