ʻO ka pōmaikaʻi nui o ke kila kila Q450NQR1, ʻo ia ka mea i hana ʻia me ke kila kalapona maʻamau a loaʻa nā mea liʻiliʻi o ke keleawe, nickel, a me nā mea ʻino ʻē aʻe. Loaʻa iā ia nā hiʻohiʻona o ka ikaika kila, ka ductility, ka hoʻokumu ʻana, ka kuʻekuʻe ʻana, ka pale ʻana, ke kiʻekiʻe wela, ka luhi a pēlā aku; ʻO ke kūpaʻa o ka wā he 2 ~ 8 mau manawa o ke kila kalapona maʻamau, a ʻo ka hana hoʻopiʻi ʻana he 1.5 ~ 10 mau manawa o ke kila kalapona maʻamau, hiki ke hoʻohana ʻia no ka ʻili lahilahi, ʻikeʻole a maʻalahi paha. ʻO ke kila nā hiʻohiʻona o ka anti-rust, corrosion resistance, lōʻihi ke ola, thinning a me ka hoʻemi ʻai ʻana, ka mālama ʻana i ka hana a me ka mālama ʻana i ka ikehu, kahi mea e pono ai nā mea hana a me nā mea hoʻohana.
ʻO nā hiʻohiʻona nui o ka mea Q450NQR1 e pili ana i ke kila haʻahaʻa haʻahaʻa me ka pale anti-rust layer a me ke kūpaʻa corrosion atmospheric, hiki ke hoʻohana ʻia e hana i nā hale kila e like me nā kaʻa, nā alahaka, nā hale kiaʻi, a me nā ipu. Ke hoʻohālikelike ʻia me ke kila kalapona, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion i ka lewa. Ke hoʻohālikelike ʻia me ke kila kila, he liʻiliʻi wale nō nā mea hoʻoheheʻe ʻana i ke kila, e like me ka phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. kila, hiki i ka 100%. He ʻumi pakeneka, no laila he haʻahaʻa ke kumu kūʻai.
