Njengoko bekuya kulindeleka kumxholo wayo ophezulu wobhedu, i-alloy 400 ihlaselwa ngokukhawuleza yi-nitric acid kunye neenkqubo ze-ammonia.
I-Monel 400 ineepropati ezinkulu zoomatshini kumaqondo obushushu angaphantsi kwe-subzero, ingasetyenziswa kumaqondo obushushu ukuya kuthi ga kwi-1000 ° F, kwaye indawo yayo yokunyibilika yi-2370-2460 ° F. Nangona kunjalo, i-alloy 400 iphantsi ngamandla kwimeko edibeneyo ngoko, iintlobo ezahlukeneyo zomsindo. ingasetyenziselwa ukwandisa amandla.
