Intsimbi yekhabhoni, ekwaziwa ngokuba yi-carbon steel, ibhekisa kwi-iron kunye ne-carbon alloys eziqulethe ngaphantsi kwe-2% ye-carbon, i-carbon steel ukongeza kwi-carbon ngokubanzi iqulethe inani elincinci le-silicon, i-manganese, i-sulfur kunye ne-phosphorus.
Yenziwe ngentsimbi eshayinayo, ekwaziwa ngokuba yintsimbi engagqwaliyo enganyangekiyo ye-asidi, ibhekisa ekungangeni komoya, umphunga, amanzi kunye nezinye izinto ezibuthathaka ezibolayo kunye nee-asidi, ii-alkali, iityuwa kunye nezinye izinto ezifunxa i-chemical media corrosion steel. Ngokwesiqhelo, intsimbi engagqwaliyo kwi-corrosion media ebuthathaka idla ngokubizwa ngokuba yi-stainless steel, kwaye intsimbi engagqwaliyo kwi-chemical media corrosion ibizwa ngokuba yi-asidi-resistant steel.
(1) Ukumelana nokugqwala kunye nokurhawuzelelwa
Intsimbi engagqwaliyo yingxubevange enganyangekiyo kukugqwala yimithombo yeendaba egqwaliyo ebuthathaka njengomoya, umphunga, amanzi kunye nemithombo yeendaba erhabaxa yamakhemikhali efana nee-asidi, ii-alkali kunye neetyuwa. Kwaye lo msebenzi ubangelwa kakhulu kukongeza into engenagqwali - i-chromium. Xa umxholo we-chromium ungaphezulu kwe-12%, umphezulu wentsimbi engagqwaliyo uya kwenza umaleko wefilimu egqwalisiweyo, eyaziwa ngokuba yifilimu yokudlulisa, kunye nolu maleko wefilimu egqwalisiweyo akuyi kuba lula ukunyibilika kwiindawo ezithile zeendaba, idlala indima entle yokuzihlukanisa, inokumelana nokugqwala okunamandla.
Intsimbi yekhabhoni ibhekisa kwi-iron-carbon alloy equlethe ngaphantsi kwe-2.11% yekhabhoni, eyaziwa ngokuba yi-carbon steel, ubulukhuni bayo buphezulu kakhulu kunentsimbi engagqwaliyo, kodwa ubunzima bukhulu, i-plasticity iphantsi, kulula ukuyigqwala.
(2) ukwakhiwa okwahlukeneyo
Intsimbi engagqwaliyo ligama elithetha intsimbi engagqwaliyo engamelaniyo ne-asidi, emelana nomoya, umphunga, amanzi kunye nezinye izinto ezibuthathaka ezibolayo okanye xa isetyenziswa ngentsimbi engagqwaliyo ibizwa ngokuba yintsimbi engagqwaliyo; kwaye iya kumelana nezinto ezibolayo zekhemikhali (ii-asidi, ii-alkali, iityuwa kunye nezinye izinto ezifakwa kwiikhemikhali) ukugqwala kwentsimbi kuthiwa yintsimbi engagqwaliyo engamelaniyo ne-asidi.
Intsimbi yekhabhoni yintsimbi edibeneyo nekhabhoni enomxholo wekhabhoni ophakathi kwe-0.0218% ukuya kwi-2.11%. Ikwabizwa ngokuba yintsimbi yekhabhoni. Ikwaqulathe amanani amancinci e-silicon, i-manganese, i-sulfur, kunye ne-phosphorus.
(3) Ixabiso
Enye into ebalulekileyo ekufuneka iqwalaselwe ngumahluko weendleko phakathi kwentsimbi yekhabhoni kunye nentsimbi engatyiwayo. Nangona iintsimbi ezahlukeneyo zineendleko ezahlukeneyo, intsimbi engatyiwayo idla ngokuba nexabiso eliphantsi kunentsimbi yekhabhoni, ikakhulu ngenxa yokongezwa kwezinto ezahlukeneyo zokudibanisa, ezifana ne-chromium, i-nickel, kunye ne-manganese, kwintsimbi engatyiwayo.
Xa kuthelekiswa nentsimbi yekhabhoni, intsimbi engatyiwayo ineenxalenye ezininzi ze-alloys ezixutyiweyo kwaye ibiza kakhulu xa ithelekiswa nentsimbi yekhabhoni. Kwelinye icala, intsimbi yekhabhoni ibandakanya ikakhulu izinto zentsimbi nekhabhoni ezingabizi kakhulu. Ukuba unebhajethi encinci kwiprojekthi yakho, intsimbi yekhabhoni isenokuba lolona khetho lulungileyo.
Yeyiphi eqinileyo, yintsimbi okanye yintsimbi yekhabhoni?
Intsimbi yekhabhoni idla ngokuba nzima ngakumbi kuba inekhabhoni eninzi, nangona ingxaki kukuba idla ngokuba nomhlwa.
Kakade ke ubulukhuni obuchanekileyo buya kuxhomekeka kudidi, kwaye kufuneka uqaphele ukuba ayibobulukhuni obuphezulu obungcono, njengoko izinto eziqinileyo zithetha ukuba kulula ukuziqhekeza, ngelixa ubulukhuni obuphantsi buhlala buqinile kwaye buncinci amathuba okuba buqhekeke.
