Steel classification nzira yakasiyana, nzira huru ine zvinotevera zvinomwe:
1, zvinoenderana nemhando yemhando
(1) simbi yakajairika (P 0.045% kana pasi, S 0.050% kana pasi)
(2) simbi yepamusoro (P, S iri 0.035% kana pasi)
(3) simbi yepamusoro (P 0.035% kana pasi, S 0.030% kana pasi)
2, iyo yakarongedzwa nemakemikari
Simbi yakapfava (1) carbon steel: a. 0.25% kana pasi (C); B. medium carbon steel (C acuities yaiva 0.25 ~ 0.60%); C. high carbon steel (0.60%) kana zvishoma c.
(2) alloy simbi: a. yakaderera alloy simbi (alloy element yehuwandu hwe5% kana pasi); B. mu alloy simbi (alloy element total content> 5 ~ 10%); C. high alloy simbi (alloy element total content> 10%).
3, maererano nekugadzira nzira yekuisa
(1) simbi yekuumba; (2) simbi yakaumbwa; (3) simbi inopisa inokungurutswa, (4) simbi inodhonzwa nechando.
4, maererano neiyo microstructure classification
(1) mamiriro ekugadzirisa: a. hypoeutectoid simbi (ferrite + pearlite); B. eutectoid simbi (pearlite); C. hypereutectoid simbi (pearlite uye cementite); D. ledeburite simbi (pearlite uye cementite).
(2) mamiriro emoto: a. pearlitic simbi; B. bainite simbi; C. martensitic simbi; D. austenitic simbi.
(3) pasina shanduko yechikamu kana chikamu chekuchinja kwechikamu
5, zvichienderana nechinangwa chekuisa
(1) kuvaka uye engineering simbi: a. zvakajairika kabhoni structural simbi; B. yakaderera alloy structural simbi; C. simbi yakasimbiswa.
(2) simbi yekugadzira: a. kugadzirwa kwemichina yakadzima uye simbi yakapfava: (a) simbi yekugadzira; (b) pamusoro pekuomesa simbi: kusanganisira carburizing simbi, permeability yeammonia simbi, pamusoro quenching simbi; (c) simbi yekucheka pasina; (d) inotonhora yepurasitiki yekugadzira simbi: inosanganisira inotonhora-yakaumbwa simbi, inotonhora musoro simbi.
B. chitubu simbi
C. kubereka simbi
(3) simbi yekushandisa: a. carbon tool simbi; B. alloy tool simbi; C. high speed tool simbi.
(4) kushanda kwakakosha kwesimbi: a. acid-uchapupu simbi isina tsvina; B. simbi inodzivirira kupisa, kusanganisira oxidation kupisa kusimba kwesimbi, simbi, simbi vharafu; C. electrothermal alloy simbi; D. kupfeka simbi isingachinji; E. cryogenic simbi; F. simbi yemagetsi.
(5) simbi yehunyanzvi, senge Bridges nesimbi, ngarava simbi, boiler simbi, kumanikidza mudziyo simbi, michina yekurima, simbi, nezvimwe.
6, kupatsanura kwakadzama
(1) simbiwo zvayo
A. Q195 carbon structural simbi: (a); (b) Q215 (A, b); (c) Q235 (A, B, c); (d) Q255 (A, B); Q275 (e).
B. yakaderera alloy structural simbi
C. yakakosha-chinangwa chakajairika simbi yekugadzira
(2) simbi yemhando yepamusoro (kusanganisira simbi yepamusoro)
A. high quality carbon structural steel structural simbi: (a); (b) alloy structural simbi; (c) chitubu simbi; (d) simbi yekucheka pasina; (e) simbi inotakura; (f) yakananga USES high quality simbi.
B. mudziyo simbi kabhoni mudziyo simbi: (a); (b) alloy tool simbi, (c) high speed tool simbi.
