| Abstract: | The welding cold crack sensitivity and weldability of hand welding,Submerged Arc welding and VEGA of 12MnNiVR steel for large crude oil storage tanks have been researched and the properties of 12MnNiVR steel analyzed.The results show that the 12MnNiVR steel in possession of very well weldability can undertake large linear energy welding（≤100 kJ/cm）and thus will be able to satisfy the need of 100 000 m3 crude oil tank and it can replace the imported steel plate.Existence of large quantity of intragranular acicular ferrite is very beneficial to achievement of very excellent comprehensive properties in the HAZ of the gas-electric welding joint. |
