Insimbi engenasici luhlobo lwentsimbi yealloyi equlethe intsimbi njengenye yezinto zayo eziphambili, kunye nechromium, nickel, kunye nezinye izinto.Ukuba insimbi engenastainless inozibuthe okanye ayinazibuthe ixhomekeke ekubunjweni kwayo okuthe ngqo kunye nendlela ecutshungulwe ngayo. Ayizizo zonke iintlobo zeentsimbi ezingenasici ezinozibuthe.Kukho iintsimbi zemagneti kunye ne-non-magnetic stainless, kuxhomekeke ekubunjweni kwayo.
Yintoni iyenziwe ngentsimbi eshayinayo?
Intsimbi engatyiwayo yintsimbi enganyangekiyo kwintsimbi, ichromium, kunye nezinye izinto ezinje nge nickel, molybdenum, okanye manganese.Ibizwa ngokuba "i-stainless" ngenxa yokuba iyamelana ne-stainless kunye ne-corrosion, iyenza ibe lukhetho oludumileyo kuluhlu olubanzi lwezicelo apho ukuqina kunye nokuchasana nezinto ezisingqongileyo zibalulekile.Insimbi engenasici iyamelana nokubola kunye nomhlwa ngenxa yezinto eziqulethwe ngaphakathi: isinyithi, i-chromium, i-silicon, i-carbon, i-nitrogen, kunye ne-manganese.Kufuneka iqulunqwe ubuncinane nge-10.5% yechromium kwaye ubuncinane be-1.2% yekhabhoni ukuze ibonwe njengentsimbi engatyiwa.
Iindidi zentsimbi engenasici
Intsimbi engenastainless iza kwiindidi okanye amabakala ahlukeneyo, nganye inokwakheka kwayo kunye neempawu zayo.La mabanga ahlulwe ngokweentsapho ezintlanu eziphambili:
1.iAustenitic Stainless Steel (300 Series):I-Austenitic stainless steel lolona hlobo luxhaphakileyo kwaye yaziwa ngeempawu zayo ezingezizo-magnetic, ukumelana nokugqwesa okugqwesileyo, kunye nokumila kakuhle.
2.I-Ferritic Stainless Steel (400 Series):I-Ferritic stainless steel inozibuthe kwaye inokumelana ne-corrosion, nangona ingenakutya njenge-austenitic stainless steel.
3.I-Martensitic Stainless Steel (400 Series):I-Martensitic steel stainless nayo inomagnetic kwaye inamandla kwaye iqinile.Isetyenziswa kwizicelo apho ukuxhathisa ukunxiba kunye nokuqina kubalulekile.Amanqaku aqhelekileyo abandakanya i-410 kunye ne-420.
4.Intsimbi yeNsimbi eDuplex:Duplex steel stainless idibanisa iipropathi zombini austenitic kunye ferritic steels stainless.Inika ukuxhathisa okugqwesileyo kokutya kunye namandla aphezulu.Amanqaku aqhelekileyo abandakanya i-2205 kunye ne-2507.
5.Imvula-Ukuqinisa intsimbi engatyiwayo:I-precipitation-hardening steel stainless steel inokuthi iphathwe ubushushu ukufezekisa amandla aphezulu kunye nobunzima.Amanqaku aqhelekileyo aquka i-17-4 PH kunye ne-15-5 PH.
Yintoni eyenza intsimbi engatyiwayo ibe yimagnethi?
Insimbi engenasici inokuba yimagnethi okanye i-non-magnetic, ngokuxhomekeke kwisakhiwo sayo esithile kunye ne-microstructure.Iipropati ze-Stainless steel magnetic zensimbi engenasici zixhomekeke kwisakhiwo sayo se-crystalline, ubukho bezinto ezidibeneyo, kunye nembali yayo yokucubungula.Intsimbi yeAustenitic engatyiwa iqhelekile ayinamagnetic, ngelixa iintsimbi ze-ferritic kunye ne-martensitic zihlala zimagnetic.Nangona kunjalo, kubalulekile ukuqaphela ukuba kunokubakho ukuhluka ngaphakathi kwinqanaba ngalinye ngokusekwe kwiintlobo ezithile ze-alloy kunye neenkqubo zokuvelisa.
