30CrMoV9 o se u'amea lea i se tulaga lautele e fa'amoemoe mo le fauina o vaega tineia ma fa'afefeteina, lea e masani ona fa'aogaina ma mulimuli ane fa'asusu. O le alloy 30CrMoV9 e masani ona gaosia e le EAF /VD /LF sosoo ai ma le electroslag refining (ESR) pe a mana'omia mo se fa'amoemoe fa'apitoa. Paʻu ma, pe a talafeagai ai, faʻapipiʻi e tuʻuina atu i suʻesuʻega ultrasonic e faʻavae i luga ole tulaga eseese e tusa ai ma manaʻoga a le au faʻatau. O pa e masani lava ona sapalai malamalama i le tulaga fa'a'ele'ele, po'o le fa'amoe fa'apitoa.
