O Fa'amanuiaga ole AR Steel?
O le Jindalai Steel e tuʻuina atu le ipu uʻamea AR i voluma tetele ma laiti i tagata mamanu ma faʻalapotopotoga o loʻo vaʻavaʻai e faʻalautele le ola tautua o vaega taua ma faʻaitiitia le mamafa o iunite taʻitasi e tuʻuina atu i le tautua.O aoga o le fa'aaogaina o ipu u'amea e fa'alavalava i fa'aoga e a'afia ai a'afiaga ma/po'o fa'ase'e fa'afeso'ota'i ma mea abrasive e tele naua.
O le ipu u'amea e tete'e a'a e matua'i umi lava ma fa'alavalava, e puipuia lelei mai ma'a ma maosiosia.O lenei ituaiga u'amea e aoga lelei i fa'aoga faigata, ma e ofoina atu ai foi ni a'afiaga.O le fa'aofuina o le ipu u'amea fa'asao o le a iu lava ina fesoasoani e fa'alautele le ola o au tusi talosaga ma fa'aititia au tau i se taimi umi.

Meatotino o AR400 MA AR500 Papatusi Uamea
O le AR400 e "fa'ama'a'a", e fa'asa'o, e fa'a'u'u mea fa'apipi'i.Ma'a'a laina ole 360/440 BHN fa'atasi ai ma le fa'aigoaina ole 400 BHN.Ole Vevela ole Au'aunaga e 400°F.O lenei oloa ipu ua fa'amoemoe mo le fa'aogaina i talosaga e mana'omia ai se paleni lelei o le fa'atupuina, fa'alelei, malosi ma le fa'asa'o.O u'amea fa'asa'o e masani ona fa'atau atu i le maaa ae le o se kemisi tumau.O nai suiga laiti i le kemisi o lo'o iai e fa'atatau i le fale gaosi oloa.O talosaga e mafai ona aofia ai le fa'aogaina i le eliina, eliina, fa'apipi'iina mea tetele, u'amea u'amea, ma alamanuia pulupulu & pepa.Laei oloa ipu ua mamanuina mo liner talosaga;e le'o fa'amoemoeina mo le fa'aogaina o ni fausaga e lagolago ai le tagata lava ia po'o ni masini si'i.
O le AR500 o se mea e "fa'ama'a'a", e tete'e abrasion, ipu fa'a'u'u.Ma'a'a laina ole 470/540 BHN fa'atasi ai ma le fa'aigoaina ole 500 BHN.O lenei oloa ipu ua fa'amoemoe mo le fa'aogaina i fa'aoga e mana'omia ai se paleni lelei o le a'afiaga, faigata ma le abrasion tete'e.O u'amea fa'asa'o e masani ona fa'atau atu i le maaa ae le o se kemisi tumau.O nai suiga laiti i le kemisi o lo'o iai e fa'atatau i le fale gaosi oloa.O talosaga e mafai ona aofia ai le fa'aogaina i le eliina, eliina, fa'apipi'iina o meafaitino, u'amea u'amea, ma falefaigaluega pulupulu & pepa.Laei oloa ipu ua mamanuina mo liner talosaga;e le'o fa'amoemoeina mo le fa'aogaina o ni fausaga e lagolago ai le tagata lava ia po'o ni masini si'i.
AR400 VS AR450 VS AR500+ Papatusi Uamea
O u'amea eseese atonu e eseese "fua" mo le uamea AR, ae o mea gaosia e faia se su'ega ma'a'a - ta'ua o le Brinell Test - e iloa ai le vaega e pa'u ai.O su'ega a Brinell e faia i mea uamea AR e masani ona fetaui ma fa'amatalaga ASTM E10 mo le su'eina o mea ma'a'a.
O le eseesega faʻapitoa i le va o AR400, AR450 ma AR500 o le Brinell Hardness Number (BHN), lea e faʻaalia ai le tulaga o le maaa.
AR400: 360-440 BHN masani
AR450: 430-480 BHN masani
AR500: 460-544 BHN masani
AR600: 570-625 BHN E masani lava (fa'aitiiti masani, ae avanoa)
