E tusa ai ma GB / T9711.1 paipa paipa uʻamea manaoga faatinoga, e tusa ai ma le vevela eseese tempering, e mafai ona vaevaeina i ituaiga nei o le tempering:
[1] Maualalo le vevela (150-250 tikeri)
O le microstructure e maua i le maualalo o le vevela faʻafefe o le martensite faʻafefe.O lona faʻamoemoe o le faʻaitiitia o le faʻamaʻiina o le mamafa ma le brittleness o le uʻamea faʻamaʻaʻaina i luga o le fale o le faatumauina o lona malosi maualuga ma le maualuga o le ofuina, ina ia aloese mai le taʻe poʻo le vave faʻaleagaina i le taimi o le faʻaaogaina.E masani ona faʻaaogaina mo ituaiga uma o mea faigaluega faʻapipiʻi carbon maualuga, fuaina o meafaigaluega, GB / T9711.1 paipa paipa paipa, taʻavale paʻu ma vaega carburizing, ma isi, o le maaa pe a uma le faʻafefe o le GENERALLY HRC58-64.
[2] Fa'afefete le vevela (250-500 tikeri)
O le microstructure e maua e ala i le fa'afefeteina o le tempered trostite.O le fa'amoemoe ia maua le malosi maualuga, fa'atapula'a fa'ama'i ma le malosi maualuga.O le mea lea, e masani ona faʻaaogaina mo ituaiga uma o GB / T9711.1 paipa paipa uʻamea ma togafitiga vevela vevela, pe a uma ona faʻafefeteina maaa e masani lava HRC35-50.
[3] Fa'afefeteina maualuga (500-650 tikeri)
O le microstructure e maua mai i le vevela maualuga o le faʻafefeteina o le sortensite.E masani lava, o le vevela o togafitiga faʻatasi ma le faʻafefe ma le faʻafefe e taʻua o le faʻafefe ma le faʻafefe.O lona faʻamoemoe o le mauaina lea o mea faʻainisinia sili atu ona lelei o le malosi, maʻaʻa, palasitisi ma le faigata.O le mea lea, e masani ona faʻaaogaina i taavale, GB / T9711.1 paipa paipa paipa, masini masini ma isi vaega taua faʻavae, e pei o le faʻaogaina o le tootoo, faʻamau, mea faʻaoga ma le faʻamau.O le maaa pe a uma le faʻafefe e masani lava HB200-330.
