(1)Indlela yokuncibilikisa insimbi
I-GB 5310 20MnG insimbi izoncibilika ngesithando somlilo sikagesi kanye nokucwengwa kwesithando somlilo, isiguquli se-oxygen kanye nokucwengisiswa kwesithando somlilo noma indlela yokuncibilikisa i-electroslag.
(2)Izindlela zokukhiqiza kanye nezidingo zezikhala zeshubhu
I-tube engenalutho ingakhiqizwa ngokusakazwa okuqhubekayo, i-die casting noma i-hot rolling (i-forging).
(3)Indlela yokukhiqiza yeshubhu lensimbi
I-GB 5310 20MnG Amashubhu ensimbi azokwenziwa ngokugoqeka okushisayo (ukunwetshwa, ukunwetshwa) noma umdwebo obandayo (ukugingqika).
