20CrMo u'amea taai vevela ie

u'amea lapotopoto pa ua fa'aaogaina lautele i masini fai, autombile faia, nofoaafi, mine masini, petoleum machinry, fa'ato'aga masini ma civil archtectue pei o ituaiga uma o shafts, fa'a sikulila, so'o so'o, meafaigaluega meafaigaluega, gears, tulaga tulaga, spanners fasteners, fausaga. vaega mo ta'avale ma masini fa'ato'aga, lima i fafo ma totonu, ta'avale ma polo mo le fa'amomoli.
GB 20CrMo uamea o se ituaiga uamea uamea Saina mo le inisinia ma le fausaga masini faamoemoega, lea e masani ona faaaoga i le tineia po o le tempering po carburizing ma quenching. 20CrMo mea o loʻo i ai le malosi maualuga o le vevela, faʻamalosi lelei, leai se faʻafefe o le ita, palasitika malulu malulu, machinability lelei ma weldability.

Talosaga

20CrMo u'amea uamea o loʻo faʻaaogaina i le gaosiga o ala faʻasalalau e le faʻaleagaina i masini kemisi ma paipa maualuga, faʻamau, vaʻavaʻa ausa, faʻavela ma faʻamalosi i le vevela galue i lalo ole 250 °C, ma vaega taua o le carburizing e pei o gears ma shafts i masini lautele. . E mafai foi ona faaaoga i le tulaga o le 1Cr13 uamea e gaosia feoaiga mamafa, maualalo turbines ausa i le superheated ausa sone omiga laasaga galue blades.
