IziQinisekiso zeNtsimbi eStainless: amaBanga Amandla kunye nokuMakisha
Iziqhoboshi zentsimbi engenastainless zibalulekile ekuqinisekiseni ukuqina kunye nokhuseleko lwezakhiwo kuwo wonke amashishini ahlukeneyo. Amanqaku abo okuqina kunye nokumakishwa kunika ulwazi oluyimfuneko ekukhetheni amacandelo achanekileyo kwizicelo ezithile. Makhe sihlolisise ukuba ezi zibizo zithetha ntoni ngemizekelo ethile ebonakalayo.
♦ ABanga Amandla
I-A2 - i-Austenitic Stainless Steel (304/304L)
Iziqhoboshi eziphawulwe "A2" zithetha intsimbi engatyiwa yi austenitic, ngokwesiqhelo ibakala 304 okanye 304L, engeyiyo imagnetic kwaye inika ukuxhathisa okulungileyo kokuhlwa okufanelekileyo ukusetyenziswa ngokubanzi. Umzekelo, uphawu lwe-"A2-70" lubonisa isiqhoboshi esenziwe ngalo mathiriyeli esinamandla okuqina amalunga nama-700 eMPa. Inombolo "70" ibhekiselele kwiklasi yepropathi yomatshini, ebonisa ukuba le fastener inokumelana ubuncinane ne-700 MPa yoxinzelelo lwe-tensile ngaphambi kokungaphumeleli.
Kwiprojekthi yolwakhiwo lwangaphandle eqhelekileyo, iibholiti ze-A2-70 zinokusetyenziselwa ukukhusela isakhelo sesinyithi kuba zinika uxhathiso olwaneleyo lomhlwa lo gama zigcina amandla awoneleyo kwimfezeko yesakhiwo.
I-A4 - i-Austenitic Stainless Steel (316/316L)
Ukutyunjwa kwe-"A4" kubhekiselele kumgangatho ophezulu we-austenitic stainless steels ezifana ne-316 okanye i-316L, eyaziwayo ngokuxhathisa okuphezulu kwi-corrosion, ngakumbi kwiindawo zaselwandle okanye zeekhemikhali. Ukumakishwa kwe-"A4-80" kubonisa i-fastener kunye namandla amancinci angama-800 MPa, ebonisa ukuba yenzelwe izicelo zamandla aphezulu apho zombini amandla kunye nokumelana nokubola kubaluleke kakhulu.
Iinjineli zaselwandle zisenokukhetha izikrufu ze-A4-80 zokukhusela izibophelelo zesikhephe kuba ezi zibophelelo azixhathisi nje kuphela ukuthotywa kwamanzi anetyuwa kodwa zikwanika amandla ayimfuneko okuqinisekisa ukusebenza ngokukhuselekileyo kwiimeko ezinzima zaselwandle.
♦ Ukumakishwa kunye nokuchongwa
Imigangatho ye-ISO
Ngaphantsi kwemigangatho ye-International Organisation for Standardization (ISO), ukumakishwa kwe-fastener kubandakanya ulwazi malunga nohlobo lwezinto eziphathekayo kunye neempawu zomatshini. Njengoko kubonwe kwimizekelo yethu, "i-A2-70" kunye ne "A4-80" inikezela ngezibonakaliso ezicacileyo zezinto kunye nobuchule bayo bokusebenza.
Imigangatho yeDIN
Kwinkqubo yeDeutsches Institut für Normung (DIN), amanani ahlukeneyo angabonisa iiklasi zempahla kunye nepropathi. Kubalulekile ukubhekisa kumaxwebhu asemgangathweni afanelekileyo ukutolika ngokuchanekileyo.
Iimpawu ezongezelelweyo
Ngaphandle kwamanqanaba okuqina, iziqhoboshi zinokuphatha ezinye iimpawu ezifana neekhowudi zomenzi, amanani obushushu, okanye amanqaku ovavanyo lokuthobelana afana ne-CE, abonisa ukuthotyelwa kwemithetho ye-European Union.
Ukukhetha i-fastener efanelekileyo yensimbi engenasici kubandakanya ukuqonda zombini ibakala lezinto eziphathekayo kunye neklasi yepropathi yomatshini eboniswe ngokumakisha. Ngokuqwalasela izinto ezifana nokuvezwa kokusingqongileyo kunye namandla afunekayo, umntu unokukhetha i-fasteners ephakamisa ukuthembeka kunye nokuphila ixesha elide kuyo nayiphi na indibano.
Enkosi ngokufunda, ukuba ufuna ukubona ngaphezulu koko sinokukunika ungalandela ezi linki zingezantsi!
