Astm A335 P1 P2 P5 P9 P11 Ingxubevange yentsimbi Umbhobho Umbhobho oshushu Intengiso eMgangathweni oPhakamileyo ngeesayizi ezahlukeneyo
Intshayelelo yeMveliso
Umbhobho we-alloy luhlobo lombhobho wensimbi ongenamthungo, ukusebenza kwawo kuphezulu kakhulu kunombhobho wentsimbi ongenamthungo, kuba olu hlobo lombhobho wentsimbi luqulethe i-Cr, ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi, ukusebenza kokumelana nomhlwa kubhetele kakhulu kunezinye. Umbhobho wensimbi, ngoko umbhobho we-alloy usetyenziswa ngokubanzi kwi-petroleum, i-aerospace, ikhemikhali, amandla ombane, ibhoyila, umkhosi kunye namanye amashishini.
Intsimbi ye-alloy yintsimbi edityaniswe neentlobo ngeentlobo zezinto kwiimali ezipheleleyo phakathi kwe-1.0% kunye ne-50% ngobunzima bokuphucula iimpawu zayo zoomatshini.Iintsimbi ze-alloy zihlulwe zibe ngamaqela amabini: i-low-alloy steels kunye ne-high-alloy steels.Umahluko phakathi kwezi zibini ngandlel’ ithile awunamkhethe: uSmith noHashemi bachaza umahluko kwi-4.0%, ngelixa i-Degarmo, et al., ichaza kwi-8.0%. Ngokuqhelekileyo, ibinzana elithi "intsimbi ye-alloy" libhekisela kwiintsimbi eziphantsi kwe-alloy.
Ukuthetha ngokuthe ngqo, zonke iintsimbi ziyi-alloy, kodwa ayizizo zonke iintsimbi ezibizwa ngokuba yi "alloy steels".Iintsimbi ezilula kakhulu ziyintsimbi (Fe) edibeneyo nekhabhoni (C) (malunga ne-0.1% ukuya kwi-1%, kuxhomekeke kuhlobo).Nangona kunjalo, igama elithi "insimbi ye-alloy" ligama eliqhelekileyo elibhekiselele kwiintsimbi kunye nezinye izinto ezixutywayo zongezwa ngamabomu ngaphezu kwekhabhoni.I-alloyants eziqhelekileyo ziquka i-manganese (eyona iqhelekileyo), i-nickel, i-chromium, i-molybdenum, i-vanadium, i-silicon, kunye ne-boron.Ii-alloyants ezingaphantsi eziqhelekileyo ziquka i-aluminium, i-cobalt, ithusi, i-cerium, i-niobium, i-titanium, i-tungsten, i-tin, i-zinc, i-lead kunye ne-zirconium.

I-ASTM A335 Umbhobho weNsimbi ongenamthungo
I-A335 ihlala ibizwa ngokuba yi-chrome moly pipe ngenxa yokwakheka kweekhemikhali ze-Molybdenum (Mo) kunye neChromium (Cr).I-Molybdenum yonyusa amandla entsimbi kunye nomda we-elastic, ukuxhathisa ukunxiba, iimpawu zempembelelo, kunye nokuqina.I-Moly yonyusa ukuchasana nokuthamba, inqanda ukukhula okuziinkozo kwaye yenza intsimbi yechromium ingachaphazeleki lula ekumbrittlement.I-Moly sesona songezo esinye esisebenzayo esonyusa amandla obushushu obuphezulu.Kwakhona kwandisa ukunyangeka kwentsimbi, kwaye inqanda ukugoba.I-Chromium (okanye i-chrome) yinto ebalulekileyo yensimbi engenasici.Nayiphi na intsimbi ene-12% okanye ngaphezulu kwe-Chrome ithathwa njengengenasici.IChrome ayinakuphinda ibuyiselwe ekuxhathiseni i-oxidation kumaqondo obushushu aphezulu.I-Chrome iphakamisa i-tensile, isivuno, kunye nobunzima kumaqondo obushushu begumbi.Ukubunjwa kwe-chrome moly alloy iron pipe yenza kube yinto efanelekileyo yokusetyenziswa kwizityalo zamandla, iindawo zokucoca, izityalo ze-petro chemical, kunye neenkonzo zentsimi yeoli apho ulwelo kunye neegesi zithuthwa ngamaqondo aphezulu kakhulu kunye noxinzelelo.
