1, kub forging nyob rau hauv cov hlau recrystallization kub saum txheej txheem forging.
2, kub dov nyob rau hauv siab tshaj qhov recrystallization kub ntawm cov txheej txheem dov.
3, txias dov: yas deformation kub hauv qab qhov kub thiab txias ntawm cov txheej txheem dov.
4, annealing: cov hlau yog maj mam rhuab mus rau qhov kub thiab txias, khaws cia rau lub sijhawm txaus, thiab tom qab ntawd txias ntawm tus nqi tsim nyog (feem ntau qeeb txias, qee zaum tswj kom txias) ntawm cov txheej txheem kev kho cua sov hlau.
5, pickling: immersed nyob rau hauv ib tug aqueous tov ntawm sulfuric acid, thiab lwm yam., kom tshem tawm oxides thiab lwm yam nyias zaj duab xis nyob rau saum npoo ntawm cov hlau. Plating, enameling, dov thiab lwm yam txheej txheem ntawm pretreatment los yog nruab nrab kev kho mob.
