3. Nāʻokoʻa ma waena 304 vsa 316 Kila kohu ʻole
E koho pono ma waena 304 a 316 kila kohu ʻole (SS), He mea nui ia e hoʻomaopopo i ko lākou mauʻokoʻa nui. Aia ma lalo nei nāʻokoʻa ka mea nui:
Kinohi
304 SS: I ka carbon (0.07%), Silikino (1%), Mang kāne (2%), Phoshorus (0.045%), Sulfur (0.015%), Nitrogen (0.10%), Chromium (18%), a me nickel (8%).
316 SS: Piha i ka carbon (0.07%), Silikino (1.00%), Mang kāne (2.00%), Phoshorus (0.045%), Sulfur (0.015%), Nitrogen (0.10%), Chromium (16%), Nickel (10%), ʻo Mybdelum (2.00%).
ʻO ka hana maʻamau i ka heleʻana i mua o Molybdenum a me nā pakeneka o ka chromium a me Nickel, e pili ana i kā lākou waiwai.
Nā Pīkuhi Propertinies
- Ka ikaika: E ana i ka ikaika nui loa e hiki ai i kahi mea ke hiki ke kauʻia ma mua o ka hoʻomau mauʻana. 304 Ss he ikaika o ka 215 Mpa, heaha 316 Ss he ikaika o ka 205 Mpa. ʻO kēiaʻano hana maikaʻi loa he mea nui no nā noi kiʻekiʻe.
- Hālulu: E hōʻike ana i ke kū'ēʻana i kahi pale o ka mea i ka deformation a me ka huhū. 316 Ss paʻakikī, me kahi pohaku 79, ua hoʻohālikelikeʻia 304 Ss AKUA 70 Rockwell b. Pela no, 316 Ua kūponoʻo SS no ka noiʻana i nā papahana e pono ai i ka paʻakikī kiʻekiʻe.
- Modulus olasticity: E hōʻike ana pehea e kū ai kahi mea i nā mea e nānā ai ma lalo o ke kaumaha. 304 ʻO Ss kahi modulus kiʻekiʻe o ka elasticity (193-200 GPA) ua hoʻohālikelikeʻia 316 SS (164 GPA), e hana hou ana i nā mea hou aku i ka deformation.
Ke kū'ē neiʻo Corrosionion
ʻO nā heluʻelua he Corrosion-resistant, aka, 316 SS, Mahalo i kānaʻike molybdenum, ʻO nā mea maikaʻi loa i ka hoʻohuliʻana i ka corrosion, i loko o ka chloride a me nā wahi a nā sulfuric acid.
ʻO kāna mau mea i hoʻonuiʻia e hōʻoia i ka hoʻomaʻemaʻe maʻalahiʻana me kaʻole o ka hopohopo ma luna o nā hopohopo.
ʻO ke kū'ēʻana
- 304 SS: Hana maikaʻi ma nā kiʻekiʻe kiʻekiʻe akā hiki paha i ka corrosion inā hoʻomau mauʻia i nā mahana ma waena o 797-1580 ° F.
- 316 SS: Mālama i ka hana ma nā mahana ma mua o 1550 ° F a ma lalo o 850 ° F, e hana hou ana ma waena o kahi ākea ākea ākea.
Kālā
Ma muli o kāna mau mea kiʻekiʻe kiʻekiʻe a hoʻohuiʻia i ka molybdenum, 316 Ss ma kahi kokoke 40% ʻoi aku ka nui o nā mea kūʻai aku 304 SS.
ʻO ka paleʻana o ka corrosition resortion e hōʻoia i ke kumukūʻai kiʻekiʻe, hana 316 Ss kahi koho uku no nā noi kūikawā.

ʻOiaiʻo kā lākou mauʻokoʻa, 304 a 316 Kaʻana like i nāʻano maʻamau maʻamau e hana ai i nā koho kūpono no nā noi he nui.
Magnesism
ʻO nā heluʻelua he mau magnetic i loko o ke kūlana i hoʻohuiʻia akā e lilo paha i magnetic i ka wā anuanu.
Ke kū'ē neiʻo Abrasion
Hāʻawi nā heluʻeluaʻelua i ke kū'ēʻana, Ke hana pono nei iā lākou no nā wahi e pili ana i kahi e kau ai a me ka waimaka he hopohopo koʻikoʻi.
Wawahua
Elua 304 a 316 Hiki ke maʻalahi maʻalahi ke maʻalahi, ʻOiai e mālama ponoʻia e pale i ka paleʻana i ka post-weld corrosionion i nā koi koi.

E hāʻawi i nāʻanoʻelua i ka hana lōʻihi a me ka paleʻana i nā kumu o nā kaiāulu.
Ikaika ikaika
ʻO nā heluʻelua he ikaika maikaʻi loa, Nā ss 304 a me ss 316 E loaʻa kahi ikaika o ka 500-700mpa, e hana ana iā lākou i kūpono no ka hana ma lalo o nā kūlana like.
5. 304 vsa 316 Kila kohu ʻole: Pehea e koho ai i ka mea kūpono?
Ke kohoʻana i ka helu kila kila kūpono kūpono e hilinaʻi nuiʻia ma luna o kaʻike kiko'ī kiko'ī a me nā koi. ʻO kēlā me kēia papa-304 a me 316-Ua loaʻa i kāna mau pono kūʻokoʻa:
