304 316L 2205 S31803 Pāpā kila kila
Hōʻike huahana:
ʻO ke kūpaʻa ʻino o ke kila kila ma muli o kona ʻano huila (Cr, Ni, Ti, Si, Al, Mn, etc.) a me kona ʻano hoʻonohonoho kūloko.
Wahi a ke ʻano hana o ka ʻōwili wela a me ka ʻōwili anuanu ʻelua ʻano, e like me nā ʻano kiko o ke ʻano kila ua māhele ʻia i 5 mau ʻano: ʻano austenite, ʻano austenite-ferrite, ʻano ferrite, ʻano martensite, ʻano paʻakikī o ka ua.
ʻO ka ili o ka pā kila kila, he kiʻekiʻe ka plasticity, ka paʻakikī a me ka ikaika mechanical, ke kū'ē i ka waikawa, ke kinoea alkaline, ka hoʻonā a me nā mea ʻino ʻē aʻe.He kila kila ʻaʻole hiki ke ʻōpala.

Hōʻike huahana:
E like me ka maʻiʻo o ka alloy element ua māhele ʻia i:
ke kila kila haʻahaʻa (ʻo ka nui o nā mea hao ma lalo o 5%),
Ke kila kila waena (5% -10% o ka nui o nā mea hoʻohuihui)
Ke kila kila kiʻekiʻe (ʻoi aku ke kiʻekiʻe o ka mea hao ma mua o 10%).
E like me ka hoʻohui ʻana o ka mea alloy i:
Ke kila Chromium (Cr-Fe-C)
Ke kila Chromium-nickel (Cr-Ni-Fe-C)
ʻO ke kila manganese (Mn-Fe-C)
Ke kila silikoni-mangane (Si-Mn-Fe-C)

Hōʻike huahana:
ʻElua mau ʻāpana o ka pā kila pale ʻaʻahu: ʻo ka pā kila haʻahaʻa a me ka ʻāpana pale pale.ʻO ka papa hana paʻa paʻa i ka alloy he 1 / 3 ~ 1 / 2 o ka nui o ka mānoanoa.I ka wā e hana ai, hāʻawi ka matrix i ka hana holoʻokoʻa e like me ka ikaika, ka paʻakikī a me ka plasticity, a hāʻawi ka pale pale pale i ka pale lole e hoʻokō i nā koi o nā kūlana hana i kuhikuhi ʻia.
ʻO ka papa paʻa paʻa paʻa ka mea nui o ka chromium alloy, a ua hoʻohui pū ʻia ka manganese, molybdenum, niobium, nickel a me nā mea ʻē aʻe.Hoʻokaʻawale ʻia ka carbide i loko o ka ʻiʻo metallographic i ke ʻano fiber, a pololei ke kuhikuhi o ka fiber i ka ʻili.Hiki i ka microhardness o ka carbide ke piʻi ma luna o HV1700-2000, a hiki i ka paʻakikī o ka honua ke hiki i ka HRC 58-62.He paʻa ikaika ka Alloy carbide i ka wela kiʻekiʻe, mālama i ka paʻakikī kiʻekiʻe, akā he waiwai antioxidant maikaʻi nō hoʻi, i loko o 500 ℃ hoʻohana maʻamau.

S235JR S275JR S355JR Pāpā kila Carbon
Hōʻike huahana:
Hoʻokaʻawale ʻia nā pā kila i nā ʻāpana ʻōwili wela a me ke anuanu.
E like me nā ʻano kila, aia nā kila maʻamau, ke kila kiʻekiʻe, ke kila kila, ke kila puna, ke kila kila, ke kila mea hana, ke kila pale wela, ke kila kila, ke kila silika a me ka ʻoihana hao maʻemaʻe.
High quality kalapona structural kila hiki ke maheleia i ekolu waeʻano e like me okoa kalapona maʻiʻo: haʻahaʻa kalapona kila (C 0.25%), waena kalapona kila (C he 0.25-0.6%) a me kiʻekiʻe kalapona kila (C & gt; 0.6%).
Hoʻokaʻawale ʻia ke kila kila kila kiʻekiʻe i ka manganese maʻamau (0.25% -0.8%) a me ka manganese kiʻekiʻe (0.70% -1.20%), ʻoi aku ka maikaʻi o nā waiwai mechanical a me nā waiwai hana.
