Abstract

The influence of alloying on the properties of high-tempered steels used for the production of casing pipes has been studied. It has been shown that an increase of molybdenum content from 0.15 to 0.53% provides a noticeable increase of the mechanical characteristics in chromium-molybdenum steels after tempering at 600‒690 °C. Alloying with vanadium and niobium contributes to an additional increase in strength properties. The influence of vanadium on the highly viscoplastic properties of steels is shown. It has been established that the greatest strengthening of steel with 0.32% molybdenum in a highly tempered state is provided by complex alloying with niobium and vanadium. The influence of austenitization and tempering temperature on the structure and properties, including resistance to cracking in an environment saturated with hydrogen sulfide, of chromium-molybdenum steel grade 26CrMoVNb-2 with micro-alloying additives of vanadium and niobium was determined. Alloying with molybdenum, vanadium and niobium makes it possible to obtain steels for high-strength casing pipes that are resistant to brittle fracture and sulfide stress corrosion cracking, subject to comprehensive consideration of the main factors such as austenitization temperature, tempering temperature and duration, dispersion and homogeneity of microstructure

耐寒和耐腐蚀型套管用高强度复合合金钢的特性

研究了合金对用于生产套管的高回火钢性能的影响。研究表明，将钼含量从 0.15% 提高到 0.53%，可显著提高铬钼钢在 600-690 °C 回火后的机械性能。与钒和铌的合金化还有助于提高强度特性。钒对钢的高粘度塑性的影响已得到证实。通过与铌和钒的复合合金化，确定了 0.32% 的钼钢在高回火状态下的最大强化作用。研究确定了奥氏体化和回火温度对含钒和铌微合金添加剂的铬钼钢 26CrMoVNb-2 的结构和性能（包括在硫化氢饱和环境中的抗裂性）的影响。通过钼、钒和铌合金化，可以获得抗脆性断裂和硫化物应力腐蚀开裂的高强度套管钢，但需要综合考虑奥氏体化温度、回火温度和持续时间、微观结构的分散性和均匀性等主要因素。
