347 Pepa kila kila, Coil a me Bar – AMS 5512, 5646

347 kila kuhiliʻole he columbium/tantalum stabilized austenitic chromium-nickel kila kuhiliʻole. Hoʻopaʻa ʻia kēia mea i ka hoʻokumu ʻana i ka chromium carbide e ka hoʻohui ʻana o columbium a me tantalum. No ka mea, ʻoi aku ka ikaika o ka pilina o kēia mau mea no ke kalapona ma mua o ka chromium, ua hoʻoheheʻe ʻia nā carbide columbium-tantalum i loko o nā kīʻaha ma mua o ka hana ʻana ma nā palena ʻai. Pono e noʻonoʻo ʻia ka 347 no nā noi e koi ana i ka hoʻomehana ʻana ma waena o 800ºF (427ºC) a me 1650ºF (899ºC) a i ʻole no ka wili ʻana ma lalo o nā kūlana e pale ai i kahi anneal post-weld. 347 ʻaʻole magnetik.
