Method of using low alloy anticoking steels with an increased silicon and manganese content in refining and petrochemicals applications

摘要

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.
