Kua tukuna e mātou he pepa maitai kore waikura 321 1*1220*2440 mō tā mātou kiritaki mai i UAE

Ngā Āhuatanga Hemi

Ko te maitai kore waikura 321 he maitai kore waikura austenitic kua whakapūmautia ki te titanium (he rite ki te 304 engari kua tāpirihia te titanium hei ārai i te maturuturunga o te chromium carbide). He tino pai te ātete ki te pāmahana teitei me te ātete ki te waikura intergranular.
