Ka ʻokoʻa ma waena o 304 a me 321 kila kila

ʻO ka ʻokoʻa nui ma waena o 304 a me 321 ke kila kila ʻaʻole i loaʻa iā 304 Ti, a ʻo 321 ka Ti. Hiki iā Ti ke pale i ka ʻike ʻana i ke kila kila. I ka pōkole, ʻo ia ka hoʻomaikaʻi ʻana i ke ola lawelawe o ke kila kila ma ka hana wela kiʻekiʻe. ʻO ia hoʻi, i loko o ke kaiapuni kiʻekiʻe, 321 pā kila kila ʻoi aku ka maikaʻi ma mua o 304 pā kila kila. ʻO ka 304 a me ka 321 he austenitic stainless steel, a ua like loa ko lākou helehelena a me nā hana kino, me nā ʻokoʻa liʻiliʻi wale nō i ka haku mele.

ʻO ka mea mua, koi ʻia ʻo 321 stainless steel e loaʻa i kahi mea liʻiliʻi o ka titanium (Ti) element (e like me nā maʻamau ASTMA182-2008, ʻaʻole pono ka liʻiliʻi o kāna ʻike Ti ma mua o 5 mau manawa o ke kalapona (C), akā ʻaʻole i emi iho ma mua o 0.7 % Nānā, 304 a me 321 ʻO ka maʻiʻo kalapona (C) he 0.08%), ʻoiai ʻo 304 ʻaʻohe titanium (Ti).

ʻO ka lua, ʻokoʻa iki nā koi no ka nickel (Ni), 304 ma waena o 8% a me 11%, a ʻo 321 ma waena o 9% a me 12%.

ʻO ke kolu, ʻokoʻa nā koi no ka ʻike chromium (Cr), 304 ma waena o 18% a me 20%, a ʻo 321 ma waena o 17% a me 19%.
