Ipleyiti yentsimbi engagqwaliyo engama-304 316L 2205 S31803
Inkcazo yemveliso:
Ukumelana nokugqwala kwentsimbi engagqwali kuxhomekeke kakhulu kulwakhiwo lwayo lwe-alloy (Cr, Ni, Ti, Si, Al, Mn, njl.njl.) kunye nolwakhiwo lwayo lwangaphakathi.
Ngokwendlela yokuvelisa i-hot rolling kunye ne-cold rolling, iintlobo ezimbini ziyafana, ngokweempawu zezicubu ze-steel, uhlobo lwe-austenite lwahlulwe lwaba ziindidi ezi-5: uhlobo lwe-austenite, uhlobo lwe-austenite-ferrite, uhlobo lwe-ferrite, uhlobo lwe-martensite, uhlobo lokuqina kwemvula.
Umphezulu wepleyiti yentsimbi engagqwaliyo uthambile, uqinile kwaye unamandla oomatshini, uxhathisa i-asidi, igesi ye-alkaline, isisombululo kunye nokunye ukugqwala kwemidiya. Yintsimbi ye-alloy engagqwali lula.

Ipleyiti yentsimbi ye-SA588 SA387 Alloy
Inkcazo yemveliso:
Ngokwesiqulatho sezinto ze-alloy, izinto ze-alloy zahlulwe zibe:
intsimbi ye-alloy ephantsi (isixa sisonke sezinto ze-alloy singaphantsi kwe-5%),
Intsimbi ye-alloy ephakathi (5% -10% yezinto ze-alloy zizonke)
Intsimbi ye-alloy ephezulu (into ye-alloy iyonke ingaphezulu kwe-10%).
Ngokwendlela izinto ezidityanisiweyo ngayo kwi-alloy element:
Intsimbi yeChromium (Cr-Fe-C)
Intsimbi yeChromium-nickel (Cr-Ni-Fe-C)
Intsimbi yeManganese (Mn-Fe-C)
Isinyithi se-silicon-manganese (Si-Mn-Fe-C)

Ipleyiti Engagugiyo, Ipleyiti Engagugiyo
Inkcazo yemveliso:
Ipleyiti yentsimbi engagugiyo yenziwe ngamacandelo amabini: ipleyiti yentsimbi enekhabhoni ephantsi kunye nomaleko ongagugiyo we-alloy. Umaleko ongagugiyo we-alloy ngokubanzi yi-1/3 ~ 1 / 2 yobukhulu obupheleleyo. Xa isebenza, i-matrix inika ukusebenza okubanzi okufana namandla, ukuqina kunye ne-plasticity, kwaye umaleko ongagugiyo we-alloy unika ukumelana nokugugiyo ukuhlangabezana neemfuno zeemeko zokusebenza ezichaziweyo.
Umaleko onganyangekiyo we-alloy ikakhulu yi-chromium alloy, kwaye i-manganese, i-molybdenum, i-niobium, i-nickel kunye nezinye izinto ze-alloy nazo zongezwa. I-carbide kwi-metallographic tissue isasazwa kwimo yefayibha, kwaye ulwalathiso lwefayibha luthe nkqo kumphezulu. Ubulukhuni be-carbide bunokufikelela ngaphezulu kwe-HV1700-2000, kwaye ubunzima bomphezulu bunokufikelela kwi-HRC 58-62. I-alloy carbide inozinzo oluqinileyo kubushushu obuphezulu, igcina ubulukhuni obuphezulu, kodwa ikwanazo neempawu ezilungileyo ze-antioxidant, ngaphakathi kwe-500℃ yokusetyenziswa okuqhelekileyo ngokupheleleyo.

Ipleyiti yentsimbi yekhabhoni ye-S235JR S275JR S355JR
Inkcazo yemveliso:
Iipleyiti zentsimbi zahlulwe zibe ziipleyiti ezigoqiweyo ezishushu nezibandayo.
Ngokweentlobo zentsimbi, kukho intsimbi eqhelekileyo, intsimbi esemgangathweni ophezulu, intsimbi ye-alloy, intsimbi yasentwasahlobo, intsimbi engatyiwayo, intsimbi yezixhobo, intsimbi engatshisi ubushushu, intsimbi ethwala imithwalo, intsimbi ye-silicon kunye ne-iron sheet ecocekileyo yemizi-mveliso.
Intsimbi yesakhiwo sekhabhoni esemgangathweni ophezulu inokwahlulwa ibe ziindidi ezintathu ngokwemixholo eyahlukeneyo yekhabhoni: intsimbi yekhabhoni ephantsi (C 0.25%), intsimbi yekhabhoni ephakathi (C yi-0.25-0.6%) kunye nentsimbi yekhabhoni ephezulu (C & gt; 0.6%).
Intsimbi yesakhiwo sekhabhoni esemgangathweni ophezulu yahlulwe yaba yi-manganese eqhelekileyo (0.25% -0.8%) kunye ne-manganese ephezulu (0.70% -1.20%), le yokugqibela ineempawu ezilungileyo zoomatshini kunye neempawu zokucubungula.
