Use of austenitic stainless steels in applications requiring anti-coking properties |
摘要 |
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.
