ʻO ke ʻano 347H he kila kila austenitic chromium kiʻekiʻe. Loaʻa i nā noi e koi ana i ke kūpaʻa wela kiʻekiʻe, nā hiʻohiʻona hoʻolālā nui ʻē aʻe:
- ʻO ke kūpaʻa like a me ka pale corrosion e like me Alloy 304
- Hoʻohana ʻia no nā lako welded koʻikoʻi ke hiki ʻole ke annealing
- ʻO ke kūpaʻa ʻana o ka oxidation maikaʻi, ma ke ʻano me ka hapa nui o nā kila kuhili ʻole austenitic
- Hiki i ke kalapona ki'eki'e ke 'oi aku ka maika'i o nā waiwai kolo ki'eki'e
Ma muli o ka Type 347H waiwai kūʻokoʻa ua hoʻohana ʻia ia i nā noi like ʻole i nā ʻoihana koʻikoʻi o kēia mau lā:
- ʻO nā paipu paila a me nā pahu
- ʻO ka paipu hoʻoheheʻe ʻaila a me ke kinoea
- ʻO nā mea hoʻomehana hoʻomālamalama
- ʻO nā paipu mahu kiʻekiʻe
- Nā paipu hoʻololi wela
- Nā mea hoʻomehana hale
- ʻO nā lako paʻa paʻa kaumaha
- ʻO nā pahu pahu mokulele a me nā apo ʻohi
Me ka pae kiʻekiʻe o ke kalapona a laila ʻo Type 347 maʻamau, Type 347H stainless steel he ʻano kemika kūʻokoʻa e pili ana i kēia:
- Fe kaulike
- Cr 17-20%
- ʻO 9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0.30% ka nui
- ʻO 0.75% ka nui
- P 0.03% ka nui
- Cb/Ta 1% ka nui
