ABSTRACT:
The use is described, in the fabrication of apparatus and equipment used in refining and in petrochemicals (for example furnace, reactor or line elements), of a steel composition comprising:at most 0.25% C;more than 1% up to 10% Mn;1.5% to 5% Si;at most 0.03% P;at most 0.03% S;4% to 10% Cr;0.5% to 2% Mo;at most 0.40% V; andat most 0.10% N;the complement to 100% being essentially iron.Steels comprising:at most 0.15% C;more than 2% up to 10% Mn;1.5% to 5% Si;at most 0.03% P;at most 0.03% S;4% to 10% Cr;more than 0.5% up to 2% Mo;at most 0.40% V; andat most 0.10% N;the complement to 100% being essentially iron; are themselves novel.
