Can be used for making various structures of oil and gas engineering (Framework for kapleulavlivateley in oil separator, and the nozzle plate distillation columns, etc.). Steel AISI 409 has proven himself as a material stable in gases produced by burning various fuel. These environments may contain a product of the total (carbon dioxide, water vapor, nitrogen, etc.) and incomplete (carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, hydrogen sulfide, etc.) combustion. Used for manufacturing enclosures and pipe systems, neutralization, recycling, recovery and discharge of exhaust gases. Here, The Spurs expresses very clear opinions on the subject. Sophisticated high-redox catalytic reactions and the presence of corrosive gas environments dictate indispensable ekonomnolegirovannoy use stainless steel AISI 409 as a structural material for the manufacture of exhaust systems, as well as for furnace and related equipment (exhaust duct, chimneys, etc.). Properties at elevated temperatures steel AISI 409 hardened by heat treatment and did not have good resistance to scaling up to 7000, while retaining their useful mechanical properties to the operating high temperatures. This steel has good resistance to oxidation at relatively high temperatures and retains high performance under conditions in which the carbon and manganese are not can be used.
Steel is classified as a 409 with occasional zharoostoykaya to 815 C and in continuous operation up to 700 C. However, the actual operating temperature depends on the operating environment. Steel AISI 409 is used only in oxidizing and neutral environments and can not be used in a reducing environment. Up to 5000 C is not observed a pronounced creep, but above this temperature mechanical properties rapidly degraded.
