Nitrogenated austenitic stainless steel with excellent hot workability

摘要

The present invention relates to nitrogenous austenitic stainless steels, in which nitrogen-containing austenitic stainless steels contain excessive amounts of refractory excess, installation of separate equipment, process loads, and nozzles by appropriately controlling the content of Mo and N among the components. An object of the present invention is to provide an excellent nitrogenous austenitic stainless steel during hot working without accompanying problems such as clogging and deterioration of corrosion resistance.;The present invention for achieving the above object by weight, C: 0.08% or less, Si: 1.0% or less, Mn: 2.0% or less, P: 0.02 to 0.04%, S: 25ppm or less, Ni: 6-11% , Ni: austenitic stainless steel with excellent hot workability, characterized in that the composition: Cr: 16 ~ 20%, O: 100ppm or less, N: 0.04 ~ 0.2%, Mo: 0.15% or less, and the rest: Fe That's the point.
