Dear Experts,

As per Sec.IX. Table QW-442 (A Numbers) for A-No.1, Mn (Max %) is 1.60 , but one of our Kiswel SAW MTC is having 1.63 (wt. %) Mn in the chemical composition of the weld metal under PWHT Condition (602 Deg.C x 9 Hrs) - It can be considered under A No.1 - Please confirm

Thank You & Regards
