TRIAL PRODUCTION OF 1Cr25Ni20Si2 HEAT-RESISTANT STAINLESS STEEL TUBE

The 1Cr25Ni20Si2 heat-resistant stainless steel is in possession of rather high resistance against oxidation,carbonization and general corrossion circumstances, being a proper material for manufacture of heat-resistant components like the heating-furnace conduit. Introduced in the paper are the main aspects of manufacture process of the said heating-furnace service pipe, including hot-piercing, cold-rolling (drawing) as well as heat-treatment and pickling of the pipe.
