Isinyithi sihlelwa kwaye sahlelwa ngokwamaqela amane: Iintsimbi zekhabhoni, Iintsimbi ze-alloy, Stainless steels Iintsimbi zesixhobo
Uhlobo 1-Iintsimbi zekhabhoni
Ngaphandle kwekhabhoni kunye nentsimbi, iintsimbi zekhabhoni ziqulethe kuphela izixa zezinye izinto.Iintsimbi zekhabhoni zezona zixhaphake kakhulu kwiibakala ezine zetsimbi, zibalelwa kwi-90% yemveliso yensimbi epheleleyo!Intsimbi yeCarbon ihlelwa ngamacandelwana amathathu ngokusekelwe kwisixa sekhabhoni kwintsimbi:
l Iintsimbi zekhabhoni eziphantsi / iintsimbi ezithambileyo (ukuya kuthi ga kwi-0.3% yekhabhoni)
l Iintsimbi zekhabhoni ephakathi (0.3–0.6%)
l Iintsimbi zekhabhoni eziphezulu (ngaphezu kwe-0.6% yekhabhoni)
Iinkampani zihlala zivelisa ezi ntsimbi ngobuninzi njengoko zingabizi kakhulu kwaye zomelele ngokwaneleyo ukuba zisetyenziswe kulwakhiwo olukhulu.
Uhlobo 2-Iintsimbi ze-alloy
Iintsimbi ze-alloy zenziwe ngokudibanisa intsimbi kunye nezinto ezongezelelweyo ze-alloying ezifana ne-nickel, ubhedu, i-chromium kunye / okanye i-aluminium.Ukudibanisa ezi zinto ziphucula amandla, i-ductility, ukumelana nokugqwala kunye nokunyanzeliswa kwentsimbi.
Uhlobo 3-Iintsimbi ezingenasici
Amanqanaba ensimbi engenasici adityaniswe ne-10-20% yechromium kunye ne-nickel, i-silicon, i-manganese kunye nekhabhoni.Ngenxa yokonyuka kwesakhono sazo sokusinda kwimozulu embi ezi ntsimbi zinokumelana nomhlwa ngendlela emangalisayo kwaye zikhuselekile ukuba zisetyenziswe kulwakhiwo lwangaphandle.Amanqanaba ensimbi engenasici asetyenziswa ngokuqhelekileyo kwizixhobo zombane.
Umzekelo, i-304 insimbi engenasici ifunwa ngokubanzi ngenxa yokukwazi kwayo ukumelana nokusingqongileyo ngelixa igcina izinto zombane zikhuselekile.
Ngelixa amanqanaba ahlukeneyo ensimbi engenasici, kubandakanywa ne-304 yensimbi engenasici, enendawo kwizakhiwo, intsimbi ecocekileyo isoloko ifunwa kwiipropati zayo zococeko.Ezi ntsimbi zifumaneka ngokubanzi kwizixhobo zonyango, iipayipi, iinqanawa zoxinzelelo, izixhobo zokusika kunye noomatshini bokutya.
Uhlobo 4-Iintsimbi zesixhobo
Iintsimbi zesixhobo, njengoko igama libonisa, zigqwesa kwizixhobo zokusika kunye nokubhola.Ubukho be-tungsten, i-molybdenum, i-cobalt kunye ne-vanadium inceda ukuphucula ukumelana nobushushu kunye nokuqina ngokubanzi.Kwaye ngenxa yokuba babambe imilo yabo naphantsi kokusetyenziswa kakhulu, zezona zinto zikhethwayo kuninzi lwezixhobo zezandla.
Ukuhlelwa kwentsimbi
Ngaphandle kwamaqela amane, intsimbi inokuphinda ihlelwe ngokusekelwe kwizinto ezahlukeneyo ezibandakanya:
Ukuqulunqwa: uluhlu lwekhabhoni, i-alloy, i-stainless, njl.
Indlela yokugqiba: kushushu kuqengqeleka, kubanda kuqengqeleka, kubanda kugqityiwe, njl.
Indlela yokuvelisa: isithando somlilo sombane, ukuphosa okuqhubekayo, njl.
I-Microstructure: i-ferritic, i-pearlitic, i-martensitic, njl.
Amandla omzimba: ngokwemigangatho ye-ASTM
Inkqubo yokukhutshwa kwe-oxidation: ukubulawa okanye ukubulawa kancinci
Ukunyangwa kobushushu: i-annealed, i-tendered, njl.
I-nomenclature yomgangatho: umgangatho wezorhwebo, umgangatho wenqanawa yoxinzelelo, umgangatho womzobo, njl.
Leliphi ibakala elingcono lentsimbi?
Akukho mgangatho wensimbi "ogqwesileyo" wendalo yonke, njengoko ibakala elifanelekileyo lensimbi yesicelo lixhomekeke kwizinto ezininzi, ezifana nokusetyenziswa okujoliswe kuyo, iimfuno zoomatshini kunye nezomzimba, kunye nemida yemali.
Amabakala entsimbi asetyenziswa rhoqo kwaye athathwa njengoluhlu oluphezulu kudidi ngalunye lubandakanya:
Iintsimbi zeCarbon: A36, A529, A572, 1020, 1045, kunye ne4130
Iintsimbi zealloyi: 4140, 4150, 4340, 9310, kunye ne-52100
Iintsimbi ezingenastainless: 304, 316, 410, kunye ne-420
Iintsimbi zesixhobo: D2, H13, kunye ne-M2
I-JINDALAI liqela eliphambili lentsimbi elinokubonelela onke amabakala ensimbi kwikhoyili, ishidi, umbhobho, ityhubhu, intonga, ibha, i-flanges, i-elbows, i-tee, njl. Nika i-Jindalai ingqiqo yokuthembela, kwaye uya kuneliseka ngemveliso.
