Kwisakhiwo seemveliso zeplastiki, izinto zezikrufu zinxulumene nezinto ezifunwa yimveliso, njengobungakanani bamandla, kunye nentsimbi engenastainless isetyenziswa ngaphandle kweplastiki, kunye nezikrufu zentsimbi zekhabhoni zisetyenziswa. ngaphakathi.Indlela yokukhetha insimbi engenasici?
I-1: Ngokwemigaqo ye-layman, i-carbon steel screws ayinayo insimbi enezinto ezixubileyo ezongeziweyo ngamabomu, kunye ne-stainless steel screws ziyintsimbi enomxholo ophezulu we-alloy wongezwa ukuthintela ukugqwala.
2: Izikrufu zetsimbi estainless zibiza kakhulu kune-carbon steel screws.
3: Ezi ntlobo zimbini zezikrufu zahlukile, ngoko ke azinakuthelekiswa.Izikrufu zentsimbi yekhabhoni zidla ngokuba zomelele kunezikrufu zentsimbi, kodwa kulula ukurusa.
Izinto zentsimbi ye-stainless steel screws kunye ne-carbon steel screws zihluke, kwaye indawo yokusetyenziswa nayo ihluke.Intsimbi yekhabhoni ayixhathisi umhlwa, kwaye iibholithi ziya kuba nomhlwa zife emva kwexesha elide.Izikrufu zentsimbi engatyiwayo zibhetele noko.

Izixhobo ze-stainless steel screws kunye ne-carbon steel screws zihluke, kwaye iindawo ezisetyenziselwa kuzo zikwahluke.
I-corrosion resistance ye-carbon steel ayilulanga, kwaye iibholiti ziya kuhlwa zife emva kwexesha elide.Iibholiti zentsimbi estainless zibhetele noko.Nazi ezinye iimathiriyeli zeebholiti zentsimbi engatyiwayo:
Ukuhlelwa kwezinto eziphathekayo zezikrufu zensimbi ezingenasici
Isetyenziselwa ukuveliswa kwezikrufu zensimbi ezingenasici.Iimathiriyeli zezikrufu zetsimbi yentsimbi zihlelwa zibe yintsimbi ye austenitic stainless, ferritic stainless steel, martensitic steel stainless kunye nemvula eqinisa intsimbi engatyiwayo.Ukukhethwa kwezikrufu zensimbi ezingenasici nako kumgaqo.Ukusuka kowuphi umba, kukuvumela ukuba ukhethe izikrufu zentsimbi engenasici ozifunayo.
Emva koqwalaselo olubanzi nolubanzi lwale miba mihlanu, ibakala, iindidi, ukucaciswa kunye nomgangatho wezinto ezizikrufu zetsimbi estainless igqitywe ekugqibeleni.
Ferritic steel stainless
Uhlobo lwe-430 yentsimbi ye-chromium eqhelekileyo inokumelana nokugqwala okungcono kunye nokumelana nobushushu kunohlobo lwe-410, kwaye imagnetic, kodwa ayinakomelezwa ngonyango lobushushu.Ilungele intsimbi engatyiwayo enokumelana nomhlwa okuphezulu kancinci kunye nokumelana nobushushu kunye neemfuno zamandla ngokubanzi.isikrufu.
Intsimbi ye-Martensitic
Uhlobo lwe-410 kunye noHlobo lwe-416 lunokuqiniswa ngonyango lokushisa, ngobunzima be-35-45HRC kunye nokucwangciswa kakuhle.Ziyakwazi ukumelana nobushushu kunye nezikhonkwane zentsimbi engenakutyiwa kwi-corrosion ngeenjongo eziqhelekileyo.Uhlobo lwe-416 lunomxholo wesulfure ophezulu kancinci kwaye yintsimbi ecocekileyo enokusika ngokulula.
Uhlobo 420, umxholo wesulfure?I-R0.15%, iipropathi eziphuculweyo zomatshini, zinokuqiniswa ngonyango lokushisa, ixabiso eliphezulu lobunzima 53 ~ 58HRC, elisetyenziselwa izikrufu zetsimbi ezingenasici ezifuna amandla aphezulu.

Imvula Eyenziwe Yaqina Intsimbi EngenaStainless
I-17-4PH, PH15-7Mo, banokufumana amandla aphezulu kunesiqhelo i-18-8 yensimbi engenasici, ngoko ke isetyenziselwa ukuqina okuphezulu, i-corrosion-resistant stainless steel screws.
I-A-286, intsimbi engasiyiyo esemgangathweni, inokumelana ne-corrosion ephezulu kuneyona isetyenziswa ngokuqhelekileyo i-18-8 uhlobo lwensimbi engenasici, kunye neempawu ezintle zomatshini kumaqondo okushisa aphezulu.Isetyenziswa njengezikrufu zentsimbi ezomeleleyo, ezinokuqina okuphezulu, ukumelana nobushushu kunye ne-corrosion, ezinokusetyenziswa ukuya kuthi ga kwi-650-700 °C.

Austenitic steel stainless
Amanqanaba asetyenziswa ngokuqhelekileyo yi-302, 303, 304, kunye ne-305, ngamabakala amane abizwa ngokuba yi-"18-8" ye-austenitic stainless steel.Ingaba i-corrosion resistance, okanye iimpawu zayo zomatshini ziyafana.Isiqalo sokukhethwa yinkqubo yenkqubo yokuvelisa i-screws yensimbi engenasici, kwaye indlela ixhomekeke kubukhulu kunye nokuma kwee-screws zensimbi ezingenasici, kwaye kuxhomekeke kubuninzi bemveliso.
Uhlobo lwe-302 lusetyenziselwa izikrufu zoomatshini kunye neebholiti zokuzibetha.
Uhlobo lwe-303 Ukuze kuphuculwe ukusebenza kokusika, inani elincinci lesulfure lifakwe kwi-Type 303 yensimbi engenasici, esetyenziselwa ukucubungula amantongomane kwi-bar stock.
Uhlobo lwe-304 lufanelekile ukusetyenzwa kwe-screws zensimbi engenasici ngenkqubo eshushu yesihloko, njengeebholiti ezichaza ixesha elide kunye neebholiti ezinkulu zedayamitha, ezinokudlula umda wenkqubo yesihloko esibandayo.
Uhlobo lwe-305 lulungele ukusetyenzwa kwezikrufu zentsimbi engenasici ngenkqubo yesihloko esibandayo, njengamandongomane akhiwe ngokubanda kunye neebholiti ezinehexagonal.
Uhlobo lwe-309 kunye nohlobo lwe-310 lunomxholo ophezulu we-Cr kunye ne-Ni kune-Type ye-18-8 yensimbi engenasici, kwaye ifanelekile kwi-screws yensimbi engenasici esebenza kumaqondo aphezulu okushisa.
Iintlobo ze-316 kunye ne-317, zombini ziqulethe i-alloying element Mo, ngoko ke amandla abo okushisa aphezulu kunye nokumelana nokubola kuphezulu kune-18-8 yensimbi engenasici.
Uhlobo lwe-321 kunye noHlobo lwe-347, Uhlobo lwe-321 luqulethe i-Ti, i-alloying element ezinzileyo, kwaye Uhlobo lwe-347 luqukethe i-Nb, ephucula ukuchasana kwe-corrosion ye-intergranular yezinto.Ifanelekile kwiindawo ezisemgangathweni zensimbi ezingenasici ezingafakwanga emva kwe-welding okanye zisebenza kwi-420-1013 °C.
