420 SS(Insimbi Engagqwali) i-thermal spray wire iyikhwalithi ephezulu eklanyelwe izinhlelo zokusebenza zokufafaza nge-arc. Yaziwa ngokumelana nokugqwala okuhle kakhulu, ubulukhuni obuphezulu, nokumelana okuhle nokugqokwa, i-420 SS iyinsimbi engenasici ye-martensitic ehlinzeka ngokuvikeleka okuqinile kwendawo. Lolu cingo luvame ukusetshenziswa ezimbonini ezifana ne-petrochemical, ukukhiqiza amandla, ezezimoto, nezasolwandle ukuze kuthuthukiswe ukuqina nempilo yezingxenye ezibalulekile. Intambo yesifutho esishisayo engu-420 SS ilungele izinhlelo zokusebenza ezidinga i-coat eqinile, engagugi enokumelana nokugqwala okumaphakathi.
Ukulungiswa kahle kwendawo kubalulekile ukuze uthole imiphumela emihle ngocingo olushisayo lwe-420 SS. Indawo okufanele igcotshwe kufanele ihlanzwe ngokucophelela ukuze kukhishwe ukungcola okunjengamafutha, uwoyela, ukungcola nama-oxides. Ukuqhunyiswa kwegrit nge-aluminium oxide noma i-silicon carbide kuyanconywa ukuze kuzuzwe ukuhwaqeka okungaphezulu kwama-microns angama-50-75. Indawo ehlanzekile futhi eqinile ithuthukisa ukunamathela kwesifutho esishisayo, okuholela ekusebenzeni okuthuthukisiwe nokuphila isikhathi eside.

I-420 SS ye-thermal spray wire iyisisombululo esihle kakhulu sokuthuthukisa izakhiwo ezingaphezulu zezingxenye ezivezwe ekugugile kanye nokugqwala okumaphakathi. Ukuqina kwayo okuphezulu nokumelana nokugqokwa okuhle kuyenza ifaneleke izinhlelo zokusebenza ezidinga ukunamathela okuqinile nokuhlala isikhathi eside. Ngokusebenzisa i-420 SS ye-thermal spray wire, izimboni zingathuthukisa kakhulu impilo yesevisi nokuthembeka kwemishini yazo kanye nezingxenye.
