Use of low-alloyed anti - coking - steels with increased silicon - and manganese content in the raffinate ion - and petroleum chemistry applications and new steel compositions

摘要

The use of a steel composition is described for the production of equipment and equipment in the refining and petrochemical industry (for example, elements of furnaces, reactors or lines), consisting of:- at most 0,25% c,- more than 1% to 10% mn,- between 1,5 and 5% si,- at most 0,03% p,- at most 0,03% s,- between 4 and 10% cr,- between 0,5 and 2% mo,- at most 0,40% v and- at most 0,10% n,- the remainder up to 100% is mainly iron.The steels, consisting of:- no more than 0,15% c,- between + as 2,00% to 10% mn,- between 1,5 to 5% si,- at most 0,03% p,- at most 0,03% s,- between 4 and 10% cr,- more than 0,5 to 2% mo,- at most 0,40% v and- at most 0,10% n,- the remainder up to 100% is mainly iron,in turn are newly.
