Arc ni laini na imara, chini ya splash, nzuri kutengeneza, nzuri slag kuondolewa.
Masizi kidogo, na utendaji bora wa mchakato wa kulehemu.
Chuma kilichounganishwa kina Cu, Ni, Cr, hivyo upinzani wake wa kutu wa anga ni mzuri, upinzani bora wa ngozi.
Tianshu Xing, shehena kubwa ya gesi ya kimiminika (LNG) yenye mita za ujazo 174,000, ilijengwa kama upinde.
