Abstract

In a ferrite-austenite two phase stainless steel, the quantity of soluble aluminum is made to be less than 0.02 wt. %, which improves impact strength. The steel is especially suitable to manufacture seamless steel pipes having improved toughness. A preferred composition comprises in weight %: C -0.03 Si 0.1-1.0 Mn 0.1-2.0 P -0.03 S -0.01 Ni 3-8 Cr 21-28 Mo 1-4 N 0.08-0.25 Sol. Al -0.02 Fe balance.
