研究分析了采用真空脱碳热处理和降低再结晶退火温度方法来纠正和预防冷变形钢管发生晶界腐蚀倾向的可能性 ,以及碳铌化合物溶解作用对晶界腐蚀倾向的影响。研究用材料选择Ф９５ｍｍ×１２ｍｍ的热挤压管、Ф６０～２０ｍｍ×７．１～２．０ｍｍ温轧管以及Ф１４ｍｍ×２ ０ｍ
The feasibility of using vacuum decarburization heat treatment and reducing the recrystallization annealing temperature to correct and prevent the tendency of grain boundary corrosion occurred in the cold deformed steel pipe and the effect of the dissolution of the carbobium compound on the grain boundary corrosion tendency were studied. Materials used to study selected Ф95mm × 12mm hot extrusion tube, Ф60 ~ 20mm × 7.1 ~ 2.0mm warm-rolled tube and Ф14mm × 20m
