Intsimbi, kubandakanywa amacandelo entsimbi, ivavanyelwa umgangatho ngeendlela ezahlukeneyo, kubandakanywa ukuvavanywa kwe-tensile, ukugoba ukudinwa ukugoba, uvavanyo loxinzelelo / ukugoba kunye novavanyo lokuxhathisa ukubola.Izinto eziphathekayo kunye neemveliso ezinxulumene nazo zingaphuhliswa kwaye ziveliswe ngexesha langempela ukugcina umkhondo wentsebenzo yekhwalithi yemveliso, enokuphepha ukubuyisela ngenxa yomgangatho kunye nokuchithwa kwezinto eziluhlaza.
Kukho iintlobo ezininzi eziqhelekileyo zentsimbi.
Intsimbi yeCarbon
Intsimbi yeCarbon, ekwabizwa ngokuba yi-carbon steel, yintsimbi ye-iron-carbon alloy enomxholo wekhabhoni (wc) ongaphantsi kwe-2%.Ukongeza kwikhabhoni, intsimbi yekhabhoni iqulethe inani elincinci le-silicon, i-manganese, isulfure kunye ne-phosphorus.
Intsimbi yeCarbon inokwahlulwa ibe ngamacandelo amathathu: intsimbi ye-carbon structural, i-carbon tool steel kunye ne-free-cut cut structural steel.I-Carbon structural steel nayo ingahlulwa ibe ziindidi ezimbini zentsimbi yesakhiwo sokwakhiwa kunye nokwakhiwa komatshini.
Ngokutsho komxholo wekhabhoni unokwahlula kwi-carbon steel ephantsi (wc ≤ 0.25%), i-carbon steel (wc 0.25% ~ 0.6%) kunye ne-carbon steel high (wc> 0.6%).Ngokutsho kwe-phosphorus, umxholo wesulfure unokwahlula kwi-carbon steel eqhelekileyo (equkethe i-phosphorus, isulfure ephezulu), i-carbon steel high quality (equlethe i-phosphorus, i-sulfure ephantsi) kunye nentsimbi yezinga eliphezulu (equlethe i-phosphorus, isulfure ephantsi).
Ukuphakama kwekhabhoni kwintsimbi yekhabhoni ngokubanzi, ukuphakama kobunzima kunye namandla, kodwa iplastiki iyancipha.
Iintsimbi zesakhiwo seCarbon
Olu hlobo lwentsimbi ngokukodwa ukuqinisekisa iimpawu zomatshini, ngoko ibakala layo libonisa iimpawu zayo zemishini, kunye namanani e-Q +, apho "Q" yenqaku lesivuno "Qu" umlingiswa wokuqala we-Hanyu Pinyin, inani libonisa ixabiso lexabiso lesivuno, umzekelo, i-Q275 ithe inqaku lesivuno se-275MPa.Ukuba ibakala liphawulwe ngoonobumba A, B, C, D, kuthetha ukuba umgangatho webakala lensimbi uhlukile, uqulethe inani le-S, P ukwenzela ukunciphisa umgangatho wensimbi ukwenzela ukuba kuphuculwe.Ukuba unobumba othi "F" uphawulwe emva kwebakala, yintsimbi ebilayo, ephawulwe "b" yensimbi ye-semi-sedentary, engabhalwanga "F" okanye "b" yensimbi ehlala phantsi.Ngokomzekelo, i-Q235-AF ithetha i-A-grade yensimbi ebilayo kunye nenqaku lesivuno se-235 MPa, kunye ne-Q235-c ithetha i-c-grade yensimbi epholileyo ene-income point ye-235 MPa.
Iintsimbi ze-Carbon structural steels ziqhele ukusetyenziswa ngaphandle konyango lobushushu kwaye kwimeko ebonelelwe ngokuthe ngqo.Ngokuqhelekileyo iintsimbi ze-Q195, i-Q215 kunye ne-Q235 zineqhekeza elincinci lekhabhoni, iipropati ezilungileyo ze-welding, iplastiki efanelekileyo kunye nokuqina, zinamandla athile, kwaye zihlala ziqengqeleka zibe ngamacwecwe amancinci, imivalo, imibhobho yentsimbi edibeneyo, njl., esetyenziswa kwiibhulorho, izakhiwo kunye nezinye izakhiwo kunye nokuveliswa kweerivets eziqhelekileyo, izikrufu, amantongomane kunye nezinye iindawo.Iintsimbi ze-Q255 kunye ne-Q275 zineqhekeza elincinci lobunzima bekhabhoni, amandla aphezulu, iplastikhi engcono kunye nokuqina, zinokudityaniswa, kwaye zihlala ziqengqeleka Zidla ngokuqengqeleka zibe ngamacandelo, imivalo kunye neepleyiti zezahlulo ezakhiweyo kunye nokwenza iindawo ezilula zoomatshini. ezifana neentonga zokudibanisa, iigiyeri, ii-couplings kunye nezikhonkwane.
