Iibholiti ze-Anchor zizikhonkco eziphambili ezikhusela izixhobo kwiziseko zesiseko. Ukhetho lwemathiriyeli luchaphazela ngokuthe ngqo umthwalo wabo{1}umthamo wokuthwala, ukuxhathisa ukubola, kunye nobomi benkonzo. Ngokuxhomekeke kwindawo yokusebenza kunye neemfuno zeprojekthi, iibholiti ze-anchor zingahlelwa kwiintlobo ezintathu eziphambili: i-carbon steel, i-alloy steel, kunye nensimbi engenasici.
Intsimbi yeCarbon yeyona nto isetyenziswa kakhulu kwibholiti ye-ankile, kubandakanywa amabakala aqhelekileyo afana ne-Q235 kunye ne-Q345. Esi sixhobo sinikeza ixabiso eliphantsi kunye namandla aphakathi. Kushushu-unyango lwediphu yegalvanizing okanye isherardizing unyango lunokomeleza ukuxhathisa umhlwa, luyenze ifanelekele isiseko somzi-mveliso jikelele kunye nesiseko sokuhlala. Umzekelo, iibholiti zentsimbi ze-Q235 ziqhele ukusetyenziselwa ukufaka izixhobo{6}}ezinzima{7}}ezinzima, ngelixa intsimbi ye-Q345, ngenxa yamandla ayo aphezulu esivuno, isoloko isetyenziselwa ukuqinisa oomatshini abakhulu okanye iziseko zebhulorho.
Iintsimbi ze-alloy (ezifana ne-40Cr kunye ne-35CrMo) ziphucula ngokubonakalayo amandla kunye nokuqina kwazo ngokudityaniswa kwezinto ezifana nechromium kunye ne-molybdenum, zizenza zilungele{2}}umthwalo okanye ifuthe{3}} iimeko zomthwalo. Emva kokucima kunye nokufudumala, ezi bholithi zinokufikelela kumandla okuqina angaphezu kwe-800 MPa kwaye zisetyenziswa ngokubanzi kwiindawo ezirhabaxa ezifana nezixhobo zetsimbi kunye noomatshini bekhemikhali. Iibholiti zentsimbi ye-alloy zifuna unyango olumnyama okanye lwe-phosphating ukuphucula ukuxhathisa umhlwa.
Izinto zensimbi ezingenasici (ezifana ne-304 kunye ne-316) zikhethwa ngokukhethekileyo kwiindawo ezifumileyo, ezine-acidic, kunye ne-alkaline ngenxa yokumelana nokugqwesa okugqwesileyo. 304 iibholiti zensimbi ezingenasici zilungele ukukhuselwa kwe-corrosion jikelele, ngelixa i-316, ngenxa yomxholo wayo we-molybdenum, yenza ngcono kwiindawo zaselwandle okanye kwizicelo zeekhemikhali. Nangona iibholiti zentsimbi zibiza kakhulu, ukugcinwa kwazo {{5}indalo yasimahla kunciphisa kakhulu-indleko zokusebenza kwexesha elide.
Kungenjalo, iialloyi zobhedu okanye iialloys zetitanium zingasetyenziswa kwizicelo ezikhethekileyo, kodwa ezi azisetyenziswanga kangako ngenxa yeendleko kunye nobunzima bokuqhuba. Ngamafutshane, ukhetho lwemathiriyeli yeebholiti ze-ankile lufuna uqwalaselo olubanzi lweempawu zoomatshini, ukuhambelana kokusingqongileyo, kunye neendleko{1}}ezisebenzayo ukuqinisekisa ukhuseleko lweprojekthi kunye nokuqina.
