titleOfInvention A kind of preparation method of the austenitic heat-resistance steel of the anti-steam corrosion of high-lasting strength
abstract The present invention relates to a kind of preparation methods of austenitic heat-resistance steel, belong to austenitic heat-resistance steel technical field.This method includes the processing steps such as dispensing, oxygen decarburization, reduction, tapping, ladle refining, casting, cogging and hot rolling successively.Steel grade SP22/15 of the present invention has similar nickel content and chrome content compared to 22/15 austenitic heat-resistance steel, but with better creep rupture strength and high temperature resistance steam corrosion, so that steel grade of the present invention has better market prospects compared to 22/15 austenitic heat-resistance steel.The present invention can substitute 22/15 austenitic heat-resistance steel comprehensively, and also adapt to some immalleable harsh conditions of 22/15 austenitic heat-resistance steel, for example be worked normally under the temperature high-pressure steam environment of 650 DEG C of 35MPa, and keep good impact flexibility.
