    摘要: A steel composition particularly suitable for the manufacture of electric resistance welded pipes for use in most hostile environments and able to display excellent sour resistance and high toughness. The aluminum content of the steel composition is reduced to not more than 0.005%, while from 0.006 to 0.2% in total of one or both of titanium and zirconium is used instead for steel containing 0.0005 to 0.008% Ca. The steel, apart from iron and unavoidable impurities further contains:0.01 to 0.35% C0.02 to 0.5% Si0.1 to 1.8% Mnnot more than 0.015% P, andnot more than 0.003% SCu, Ni, Cr, Mo, Nb and V may be added in appropriate amounts to enhance the steel performance.
