Ntxiv nrog rau kev ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, kev sim hydrostatic tau ua ib qho los ntawm ib qho, thiab kev sim flaring thiab flattening yog ua. . Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj, thiab decarburization txheej ntawm cov yeeb nkab steel tiav.
