ʻO ke ʻano 904L he kila kila austenitic kiʻekiʻe i ʻike ʻia no kāna mau waiwai corrosion. Hāʻawi kēia ʻano kalapona haʻahaʻa o Type 904 stainless steel i nā pono ʻē aʻe i nā mea hoʻohana e like me:
- Non-magnetic
- ʻOi aku ka ikaika o nā waiwai ʻino ma mua o Type 316L a me 317L
- Kūleʻa maikaʻi i ka sulfuric, phosphoric a me ka acetic acid
- Kū'ē kiʻekiʻe i ka crevice a me ke koʻikoʻi i ka haki ʻana
- Maikaʻi formability a weldability
Ma muli o nā pono āpau o ka hoʻohana ʻana i ke kila kila kila Type 904L, hiki ke loaʻa iā ia ma nā noi he nui i nā ʻano ʻoihana koʻikoʻi e like me:
- Mea hooluolu no ka wai kai
- Ka hana kemika o ka sulfuric, phosphoric a me ka acetic acids
- Nā mea hoʻololi wela
- Nā paipu condenser
- Holoi kinoea
- Ka mana a me ka mea kani
- ʻOihana ʻaila a me ka ʻaila
- ʻO ka hana lāʻau lapaʻau
- ʻO ka uwea ʻana i nā precipitators electrostatic
I mea e noʻonoʻo ʻia ai ʻo Type 904L, pono e loaʻa i kahi kila kuhili ke loaʻa kahi hui kemika kūʻokoʻa e pili ana i kēia:
- Fe kaulike
- Ni 23-28%
- Cr 19-23%
- Mo 4-5%
- Mn 2%
- Cu S 1-2.0%
- ʻO 0.7%
- S 0.3%
- N 0.1%
- P 0.03%
