Development of 2.25Cr-1Mo-0.25V Steel Hydrogenater and Some Problems on the Fabrication
摘要
Abstract
The growing demand for increased size of hydrogenators operating at higher process conditions, Vanadium has been added to 2. 25Cr - 1Mo steel to enhance high temperature strength in 80s of 20th century. The addition of Vanadium influences hydrogen trapping, diffusion and stress relaxation, and response to welding and heat treatment. Fabrication procedure must be adjusted to avoid high hardness, low ductility and low rupture stress for weldments. Examples of past problems in 2.25Cr - 1Mo -0.25V steel pressure vessel fabrication and recent research works abroad were briefly introduced. Some suggestions of research program were presented.关键词
