摘要
Abstract
Under the same test conditions,cold cracking susceptibility and reheat cracking susceptibility of B610CF-L2 and JFE-HITEN610U2L steel alloy has been investigated by the maximum hardness,Y-groove test method and implant test in weld heat affected zone.Welding linear energy, related mechanics performance test and series of temperature impact test of welding joints is introduced, and toughness -brittleness transition temperature is also identified.Results show that the steel alloys have the same low cold cracking susceptibility and certain extent reheat cracking susceptibility,and former's reheat cracking susceptibility is lower than the latter.lt also illustrates that the ranges of welding linear energy are all wide,the mechanical properties of welding joints are at the same level, they are all of high quality in low temperature toughness with Akv2≥47J at -50 ℃ and their toughness-brittleness transformation temperature vTt.vTs＜-50℃.They are adapted to -50℃ 2 000 m3 cryogenic ethylene spherical tank.关键词
