  • Use of austenitic stainless steels in applications requiring anti-coking properties
    Patent number: 6824672
    Abstract: An austenitic stainless steel with a composition comprising: at most 0.15% of C; 2% to 10% of Mn; at most 2% of Ni; at most 4% of Cu; 0.1% to 0.4% of N; 10% to 20% of Cr; at most 1% of Si; at most 3% of Mo; and at most 0.7% of Ti; is used to manufacture equipment, for example furnaces, reactors or ducts, or elements of this equipment, or to coat the internal walls of this equipment, said equipment being used to implement petrochemical processes conducted at temperatures of 350° C. to 1100° C. and in which coke can be formed.

  • Apparatus comprising furnaces, reactors or conduits having internal walls comprising at least partly of a steel alloy
    Patent number: 6235238
    Abstract: In order to produce elements for furnaces, reactors or conduits on the walls of which coke can appear, steels are used with a composition which is adapted to resist coking comprising, by weight, at most 0.25% of C, 1.5% to 5% of Si, 4% to 10% of Cr, 0.5% to 2% of Mo, 0.3% to 1% of Mn, at most 0.030% of S and at to most 0.03% of P, the complement to 100% being essentially iron. Novel steel compositions for use in these applications are those which comprise, by weight, at most 0.25% of C, more than 2.5% and up to 5% of Si, 4% to 10% of Cr, 0.5% to 2% of Mo, 0.3% to 1% of Mn, at most 0.03% of S and at most 0.03% of P, the complement to 100% being essentially iron.
