(2) insimbi yekhwalithi ephezulu (P, S ingu-0.035% noma ngaphansi)
(3) insimbi yekhwalithi ephezulu (P 0.035% noma ngaphansi, S 0.030% noma ngaphansi)
2, okuhlukaniswa ngamakhemikhali
Insimbi ethambile (1) carbon steel: a. 0.25% noma ngaphansi (C); B. medium carbon steel (C acuities kwaba 0.25 ~ 0.60%); C. high carbon steel (0.60%) noma ngaphansi c.
(2) insimbi yengxubevange: a. insimbi ephansi ye-alloy (okuqukethwe kwe-alloy element yengqikithi engu-5% noma ngaphansi); B. kunsimbi ye-alloy (ingqikithi yokuqukethwe kwe-alloy element> 5 ~ 10%); C. insimbi ephezulu yengxubevange (ingqikithi yokuqukethwe kwento yengxubevange > 10%).
3, ngokwendlela yokwakha yokuhlukanisa
(1) insimbi yokubumba; (2) insimbi; (3) insimbi egoqiwe eshisayo, (4) insimbi edonsa ngamakhaza.
4, ngokuya ngezigaba ze-microstructure
(1) isimo sokuthungatha: a. insimbi ye-hypoeutectoid (i-ferrite + pearlite); B. insimbi ye-eutectoid (pearlite); C. insimbi ye-hypereutectoid (i-pearlite ne-cementite); D. insimbi ye-ledeburite (i-pearlite ne-cementite).
(2) isimo somlilo: a. insimbi ye-pearlitic; B. bainite insimbi; C. insimbi ye-martensitic; D. insimbi ye-austenitic.
(3) ngaphandle koshintsho lwesigaba noma ingxenye yoshintsho lwesigaba
5, ngokwenhloso yokuhlukanisa
(1) insimbi yokwakha nobunjiniyela: a. insimbi evamile ye-carbon structural; B. insimbi ephansi ye-alloy structural; C. insimbi eqinisiwe.
(2) insimbi yesakhiwo: a. ukukhiqiza imishini insimbi ecishiwe nepholile: (a) insimbi yesakhiwo; (b) insimbi eqinisa indawo engaphezulu: okuhlanganisa insimbi yokungcwatshwa, ukungena kwensimbi ye-ammonia, insimbi yokucisha indawo; (c) insimbi yokusika mahhala; (d) insimbi eyakha ipulasitiki ebandayo: okuhlanganisa insimbi eyakhelwe ukubanda, insimbi enesihloko esibandayo.
B. insimbi yasentwasahlobo
C. insimbi enensimbi
(3) insimbi yensimbi: a. insimbi yensimbi ye-carbon; B. insimbi yensimbi yensimbi; C. izinsimbi zamathuluzi esivinini esikhulu.
(4) ukusebenza okukhethekile kwensimbi: a. insimbi engagqwali ene-asidi; B. insimbi ekwazi ukumelana nokushisa, okuhlanganisa insimbi yokushisa kwe-oxidation, insimbi, i-valve yensimbi; C. insimbi ye-electrothermal alloy; D. gqoka insimbi eqinile; E. insimbi ye-cryogenic; F. insimbi kagesi.
(5) insimbi yobungcweti, njengamabhuloho anensimbi, insimbi yomkhumbi, insimbi yokubhayela, insimbi yomkhumbi wengcindezi, imishini yezolimo, insimbi, njll.
6, ukuhlukaniswa okuphelele
(1) insimbi evamile
A. Q195 carbon structural steel: (a); (b) Q215 (A, b); (c) Q235 (A, B, c); (d) Q255 (A, B); Q275 (e).
B. insimbi ephansi ye-alloy structural
C. insimbi yesakhiwo esinenhloso ekhethekile
(2) insimbi yekhwalithi ephezulu (kuhlanganise nensimbi yekhwalithi ephezulu)
A. izinga eliphezulu carbon structural steel structural steel: (a); (b) ingxube yensimbi yesakhiwo; (c) insimbi yasentwasahlobo; (d) insimbi yokusika mahhala; (e) insimbi enensimbi; (f) ethize ISEBENZISA insimbi yekhwalithi ephezulu.
B. insimbi yensimbi yensimbi yensimbi yensimbi: (a); (b) insimbi yensimbi eyingxubevange, (c) izinsimbi zamathuluzi esivinini esikhulu.
