(2) intsimbi yengxubevange: a. intsimbi ephantsi ye-alloy (umxholo we-alloy element ye-5% okanye ngaphantsi); B. kwintsimbi ye-alloy (i-alloy element iyonke umxholo> 5 ~ 10%); C. insimbi ephezulu ye-alloy (i-alloy element iyonke umxholo> 10%).
3, ngokwendlela yokwenza ulwahlulo
(1) intsimbi yokwenza; (2) intsimbi etyhidiweyo; (3) intsimbi eqengqelekayo eshushu, (4) intsimbi etsalwa ngokubanda.
4, ngokohlelo lwe-microstructure
(1) imo yokuphelisa: a. intsimbi ye-hypoeutectoid (i-ferrite + pearlite); B. intsimbi ye-eutectoid (pearlite); C. intsimbi ye-hypereutectoid (i-pearlite kunye ne-cementite); D. intsimbi ye-ledeburite (i-pearlite kunye ne-cementite).
(2) yimeko yomlilo: a. intsimbi yepearlitic; B. bainite intsimbi; C. intsimbi ye-martensitic; D. intsimbi austenitic.
(3) ngaphandle kokutshintsha kwesigaba okanye inxalenye yenguqu yesigaba
5, ngokwenjongo yohlelo
(1) intsimbi yokwakha kunye nobunjineli: a. intsimbi eqhelekileyo ye-carbon structural; B. intsimbi ephantsi ye-alloy; C. intsimbi eyomeleziweyo.
(2) intsimbi yolwakhiwo: a. ukuveliswa koomatshini bentsimbi ecinyiweyo nepholileyo: (a) intsimbi yokwakha; (b) intsimbi eqinisa umphezulu: kubandakanywa intsimbi yokugquma, ukungeneka kwentsimbi ye-ammonia, intsimbi yokucima umphezulu; (c) intsimbi yokusika simahla; d
B. intsimbi yasentwasahlobo
C. ukuthwala intsimbi
(3) isixhobo sentsimbi: a. carbon isixhobo intsimbi; B. isixhobo sentsimbi yentsimbi; C. high speed isixhobo steels.
(4) ukusebenza okukhethekileyo kwentsimbi: a. insimbi engenasici; B. intsimbi ukumelana nobushushu, kubandakanywa oxidation ubushushu ubunzulu intsimbi, intsimbi, ivelufa yentsimbi; C. intsimbi ye-electrothermal alloy; D. nxiba intsimbi exhathisayo; E. intsimbi cryogenic; F. intsimbi yombane.
(5) intsimbi yobuchwephesha, njengeBridges ngentsimbi, intsimbi yenqanawa, intsimbi yebhoyila, intsimbi yoxinzelelo lwenqanawa, oomatshini bezolimo, intsimbi, njl.
6, ulwahlulo olubanzi
(1) intsimbi eqhelekileyo
A. Q195 intsimbi yesakhiwo sekhabhoni: (a); (b) Q215 (A, b); (c) Q235 (A, B, c); (d) Q255 (A, B); Q275 (e).
B. intsimbi ephantsi ye-alloy structural
C. injongo ekhethekileyo yentsimbi eqhelekileyo yesakhiwo
(2) intsimbi ekumgangatho ophezulu (kubandakanywa nentsimbi ekumgangatho ophezulu)
A. umgangatho ophezulu we-carbon structural steel structural steel: (a); (b) intsimbi yokwakha ingxubevange; (c) intsimbi yomthombo; (d) intsimbi yokusika simahla; (e) intsimbi enentsimbi; (f) ethile USEBENZISA intsimbi ekumgangatho ophezulu.
B. isixhobo sentsimbi yentsimbi yentsimbi yentsimbi: (a); (b) intsimbi yentsimbi yentsimbi, (c) iintsimbi zesantya esiphezulu.
