Abstract

Using 2. 5%Ni steelplates for LPG storage tanks, the effect of C content on crack initiation toughness of the fusion boundary of the MIG (metal inert gas) welded joint and the effects of processing conditions in controlled rolling and accelerated cooling on mechanical properties of base plate were investigated. The experimental results indicated that the minimum crack initiation toughness of the welded joint was improved by decreasing C content. Furthermore, the crack arrestability of the 0. 01%C-2. 5%Ni steel plate was improved by reducing ferrite grain diameter and decreasing solute Nb. On the basis of the experimental results, a 0. 01%C-2. 5%Ni steel plate with good crack arrestability in base plate and also good initiation toughness in welded joint was produced by LPG storage tanks using the thermo-mechanical control process.
