Abstract

PURPOSE: A steel containing normal alloy elements is added with a composition of REM (rare earth metal), one or more of Ca and Mg, and the content of S and O is specified, to thereby invariably provide steel capable of giving toughness to electrically seamed welded zone.
CONSTITUTION: A steel for electrically seamed pipe containing normal alloy elements further includes REM (rare earth metal): 0.003 to 0.1%, one or more of Ca: 0.0001 to 0.1%, Mg: 0.0001 to 0.1% (with total being less than 0.1%), together with restricted amount of impurities such that S: below 0.002%, O: below 0.004% thereby the provide toughness to welded zone, wherein normal alloy is C, Si, Mn and, if required Ni, Mo, Cu, Cr, etc.
