Birta birta ah
Adag la heli karo:
GP: HRC46-50
Alaabooyinka dhawaan la sameeyay ee xagal leh, gogosha ayaa si tartiib tartiib ah loo soo koobay iyadoo la isticmaalayo waxayna si gaar ah ugu habboon tahay daawaynta hore ee maqaarka oksaydhka.
GL: HRC56-60
Way ka adag tahay birta GP-ga, sidoo kale waxay luminaysaa cidhifkeeda fiiqan inta lagu jiro tallaalka oo si gaar ah ugu habboon codsiyada diyaarinta dusha sare.
GH: HRC63-65
Adayg sare, geeso fiiqan ayaa hadhaya inta lagu jiro hawlgalka, inta badan loo isticmaalo qalabka wax qarxinta ee hawo-mareenka ah.
Xoogga Wax-soo-saarka:
TAA waxay qabataa teknooloojiyada Quenching Foornada Arc, kaas oo dammaanad qaadaya walxaha kiimikada ka samaysan ee birta ah iyo xoog sare, adkeysi sare, nolol adeeg oo dheer.
