420 SS(Stainless Steel) uea hoʻoheheʻe wela he mea kiʻekiʻe kiʻekiʻe i hoʻolālā ʻia no nā noi hoʻoheheʻe arc. ʻIke ʻia no kona pale ʻana i ka corrosion maikaʻi loa, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa ʻaʻahu maikaʻi, ʻo 420 SS kahi kila kila martensitic e hāʻawi i ka pale ʻana i ka ʻili. Hoʻohana maʻamau ʻia kēia uea i nā ʻoihana e like me ka petrochemical, power generation, automotive, a me ke kai e hoʻonui ai i ka lōʻihi a me ke ola o nā mea koʻikoʻi. ʻO ka 420 SS thermal spray uea he mea kūpono ia no nā noi e koi ana i kahi uhi paʻa paʻa me ka pale ʻana i ka corrosion haʻahaʻa.
He mea koʻikoʻi ka hoʻomākaukau ʻana i ka ʻili no ka loaʻa ʻana o nā hopena maikaʻi loa me ka 420 SS thermal spray wire. Pono e hoʻomaʻemaʻe ʻia ka ʻili e uhi ʻia e wehe i nā mea haumia e like me ka momona, ka aila, ka lepo, a me nā oxides. Manaʻo ʻia ka hoʻoheheʻe ʻana me ka alumini oxide a i ʻole ka silika carbide e hoʻokō i ka ʻili o 50-75 microns. Hoʻonui ka ʻili maʻemaʻe a paʻakikī i ka hoʻopili ʻana o ka uhi ʻana i ka wela, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka hana a me ka lōʻihi.

He hopena maikaʻi loa ka 420 SS no ka hoʻonui ʻana i nā waiwai o ka ʻili o nā ʻāpana i ʻike ʻia i ka ʻaʻahu a me ka corrosion haʻahaʻa. ʻO kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu maikaʻi e kūpono ia no nā noi e koi ana i kahi uhi paʻa a lōʻihi. Ma ka hoʻohana ʻana i ka uea wela wela 420 SS, hiki i nā ʻoihana ke hoʻomaikaʻi nui i ke ola lawelawe a me ka hilinaʻi o kā lākou mau mea hana a me nā ʻāpana.
