ASTM a128 iyo standard inotsanangura mamiriro emakemikari, masangano ezvivakwa, esangano reMeterlograph, kuomarara uye kukanganisa kweiyo manganne yakakwira. Pakati pavo, kuumbwa kwemakemikari chimwe chezvinhu zvakakosha kuti uve nechokwadi chekuti zvakanaka kupfeka kurwisa uye kukanganisa kuramba kweiyo manganne yakakwira simbi yekukanda. Sekureva kweiyo standard, main komical emmical emanganese ekukasira simbi Uye zvakare, chiyero ichi chinoda kuti sangano reDhonalographic uye saizi yekristaro yekukanda ichaedzwa kuti ive nechokwadi chekupfeka zvakanaka uye kukanganisa.
Panyaya yezvimiro zvekushandisa, ASTM A128 chiyero chinoda kuti tensile, kuomarara uye kukanganisa miedzo yeiyo manganse monganese. Kuburikidza nemiedzo iyi, iyo indekisi yekuita yesimba rine simba, gohwo simba, elongation, kuomarara uye kuomarara kukanganiswa kunogona kuongororwa kuti vave nechokwadi chekuti vanogona kupfekedza kukanganiswa uye kupfeka panguva yekushandisa.
Pamusoro pekuumbwa kwemakemikari uye michina yezvivakwa, iyo ASTM A228 zviyero zvakaratidzawo zvinodiwa pakupisa kwekurapa uye mamiriro emhando yepamusoro-monganese. Kuita kwekurapa kwekupisa kunogona kugadzirisa chimiro chesangano uye kuita kwekukanda, uye kugadzirisa kupfeka kwaro kupesana uye kukanganisa kuramba. Zvinodiwa zvemhando yepamusoro zvinosanganisira mamiriro ekunze
Kazhinji, ASTM A128 yakajairika inotonga uye inoongorora maitiro uye mhando yekakwirira-monganese simbi yekukanda kuti ive nechokwadi chekuti vanogona kuzadzisa zvinodiwa mugodhi, kugadzirwa uye mimwe minda yeindasitiri. Nekutevera iyi standard, yakakwirira-manganse simbi yekukanda pamwe nekupfeka zvakanaka kupokana uye kukanganisa kuramba kunogona kugadzirwa, uko kunopa yakavimbika kuvandudza kwekukura uye kushandiswa kweshanduro yezvibvumirano zvine chekuita.
