Yintoni umahluko phakathi kwe-Q235 kunye ne-SS400?

I-Q235 kunye ne-SS400 ziintsimbi ezimbini zekhabhoni ezisetyenziswa kakhulu ezithathwa njengezifanayo ekusebenzeni, kodwa zivela kwimigangatho eyahlukeneyo yesizwe kwaye zinomahluko omncinci kwimilo yeekhemikhali kunye neempawu zoomatshini. I-Q235 ichazwa phantsi komgangatho we-GB/T 700 waseTshayina, ngelixa i-SS400 iwela phantsi komgangatho we-JIS G3101 waseJapan. Nangona zisuka ngokwahlukileyo, zihlala zisetyenziswa kwizicelo ezifanayo zesakhiwo ezifana neebhulorho, izakhiwo, kunye neendawo zoomatshini.

Ngokwekhemikhali, zombini i-Q235 kunye ne-SS400 ziintsimbi ezinekhabhoni ephantsi, ezenziwe kakhulu ngentsimbi eneekhabhoni ezincinci, i-manganese, i-phosphorus, kunye nesalfure. I-Q235 idla ngokuba nomxholo ophezulu wekhabhoni oyi-0.22%, kwaye imida kwezinye izinto ingqongqo ukuqinisekisa ukudityaniswa okungcono kunye nokuguquguquka. I-SS400 inokwakheka okufanayo kodwa ivumela ukuguquguquka okungakumbi kwizinto ezithile ngokuxhomekeke kwinkqubo yokwenziwa. Olu mahluko ludla ngokuba mncinci, kodwa kwezinye izicelo—ingakumbi ezo zibandakanya iimfuno ezichanekileyo zokudityaniswa okanye isiqinisekiso sezinto zamazwe ngamazwe—zinokuba zibalulekile.

Ngokwemichiza, i-Q235 ibizwa ngegama lamandla ayo okuvelisa angama-235 MPa, ngelixa i-SS400 inika amandla okuvelisa afanayo angama-245 MPa. Amandla azo okutsalwa nawo awela kuluhlu olufanayo, ngokubanzi phakathi kwama-375 ukuya kuma-500 MPa. Ngenxa yoko, zombini ezi ntsimbi zinokusebenza ngempumelelo kwizicelo zesakhiwo kwaye zihlala zisetyenziswa ngokutshintshana xa imigangatho yendawo ivuma. Nangona kunjalo, kubalulekile ukuqaphela ukuba ukutshintshwa kwezinto kufuneka kuhlale kuvunyiwe ziinjineli zesakhiwo okanye amagunya oyilo, ngakumbi kwiiprojekthi ezilawulwayo okanye ezibalulekileyo kukhuseleko.

Ngokuphathelele ukusetyenziswa, i-Q235 ixhaphake kakhulu kwimarike yasekhaya yaseTshayina kwaye idla ngokukhethwa ukwakhiwa okungabizi kakhulu kunye nokwenziwa ngokubanzi. I-SS400, njengoko isetyenziswa eJapan, yamkelwe kakhulu eJapan nakwezinye iindawo zaseAsia. Xa kubandakanyeke urhwebo lwamazwe ngamazwe, ukhetho phakathi kwe-Q235 kunye ne-SS400 lunokuxhomekeka ekufumanekeni kwekhonkco lokubonelela, iimfuno zesatifikethi, kunye nokukhetha kwabathengi. Ekugqibeleni, nangona i-Q235 kunye ne-SS400 zifana ngeendlela ezininzi, ukuqonda umahluko wazo ocacileyo kuqinisekisa ukwenziwa kwezigqibo ezingcono ekukhetheni izinto.
