I-ASTM A128 iMigangatho yinkqubo esemgangathweni ye-manganese yensimbi ephezulu ye-manganese, elungele ukuvelisa i-subles, entloko, kwaye inxibe i-hammer ye-hammer, yokwakha, kunye neminye imimandla yamashishini.
I-ASTM A128 IMIQATHANGO Icacisa ubume bekhemikhali, iipropathi zoomatshini, umbutho weze-inion, ubunzima kunye nefuthe lokusebenza kwempembelelo ye-manganese yensimbi ye-manganese. Phakathi kwazo, ukwakhiwa kwamachiza yenye yezona zinto zibalulekileyo ukuqinisekisa ukunyangwa okuhle nokunganyangeki kwempembelelo kwentsimbi ephezulu ye-manganese. Ngokutsho komgangatho, amacandelo aphambili eekhemikhali ze-Steeleni zensimbi ye-manganese iquka i-carbon (c), i-manganese (Mn), i-SILICUR (P), i-SILICUR (P), kunye nomxholo we-manganese uhlala phakathi kwe-11% ne-14%. Ukongeza, umgangatho ufuna ukuba ubungakanani be-nimemic kunye nobungakanani beekristali ze-ving bavavanywe ukuqinisekisa ukunyangwa okuhle kunye nokunganyangeki kwempembelelo.
Ngokwemigangatho yoomatshini, i-ASTM A228 imigangatho ifuna u-Gensle, ubunzima kunye novavanyo lwempembelelo ye-manganese yensimbi ye-manganese. Ngezi vavanyo, iikondi zentsebenzo zamandla e-thensul, ukuvelisa amandla, i-elouty, ubunzima kunye nobunzima bempembelelo bunokuvavanywa ukuqinisekisa ukuba banokuzivalisa impembelelo enkulu kwaye banxibe ngexesha lokusetyenziswa.
Ukongeza kubume bekhemikhali kunye neepropathi zoomatshini, imigangatho ye-ASTM imigangatho ikwabeka iimfuno zenkqubo yobushushu yonyango kunye nomgangatho womhlaba we-manganese shol. Inkqubo yonyango lobushushu inokuphucula imeko yombutho kunye nokusebenza kokuphosa, kwaye iphucule ukunyangwa kwayo kunye nokunganyangeki kwempembelelo. Iimfuneko zomgangatho womphezulu zibandakanya ukrwada, iziphene kunye ne-oxide ukuba iqinisekise ukuba ukuphosa kunokugcina imeko elungileyo ngexesha lokusetyenziswa.
Ngokubanzi, i-ASTM A128 ilawula ngokungqongqo kwaye ihlole intsebenzo kunye nomgangatho wensimbi ye-SEXAnese ephezulu yokuqinisekisa ukuba banokuhlangabezana neemfuno zokusetyenziswa, ukwakhiwa kunye namanye amabala eshishini. Ngokulandela lo mgangatho, i-manganese yentsimbi ephezulu yokulahla ukunyangwa okuhle kunye nokuchaswa kwempembelelo, nto leyo ebonelela ngesiqinisekiso esithembekileyo kuphuhliso kunye nokusetyenziswa kwamashishini ahambelana noko.
