Koho Uea Uea Wela i olokaaia SAE1018

He mea metala koʻikoʻi ʻo SAE1018 e hahai ana i nā lula inoa AISI. Loaʻa iā ia ka hao, carbon, manganese, a me nā mea ʻē aʻe.

Pono ka mālama mau ʻana e hoʻonui i ke ola lawelawe.

Kaomi ma ka ʻaoʻao e aʻo hou aku!

Ua hahai ʻo SAE1018 i nā lula inoa o ka American Iron and Steel Institute (AISI), kahi ʻo "10" e hōʻike ana i ke kila manganese kalapona a ʻo "18" e hōʻike ana i kona awelika kalapona ma kahi o 0.18% (ma waena paha o ka 0.15% a me ke kalapona. 0.25%). Ua kapa ʻia ʻo ia ke kila kila maʻamau a i ʻole ke kila kila kila, a ʻo ka maʻamau i hoʻokō ʻia ʻo ASTM a i ʻole SAE J403-2001.

ʻO ka hui kemika o ke koʻokoʻo uea kila SAE1018 ka nui o ka hao (Fe), carbon (C), manganese (Mn), silicon (Si) a me kahi liʻiliʻi o ka phosphorus (P), sulfur (S) a me nā mea ʻē aʻe. ʻO ke ʻano kikoʻī o ka hui ʻana kemika penei:

Kalapona (C): 0.15%~0.25%

Manganese (Mn): 0.60%~1.00%

Silika (Si): 0.15%~0.35%

Phosphorus (P): ≤0.04% (hōʻike kekahi mau ʻikepili ≤0.035%)

Sulfur (S): ≤0.05%

Eia hou, hiki ke loaʻa i ka nui o ka chromium (Cr), ke keleawe (Cu), nickel (Ni) a me ka molybdenum (Mo), akā haʻahaʻa ka maʻiʻo.

Nā waiwai mīkini

ʻO ke koʻokoʻo uea kila wela SAE1018 he mau waiwai mechanical maikaʻi loa, ʻo ia hoʻi:

Ka ikaika tensile: ≥450MPa (hōʻike kekahi mau ʻikepili e pili ana i 410MPa, ʻokoʻa paha ka waiwai kikoʻī ma muli o nā ʻāpana like ʻole a i ʻole nā kaʻina hana).

Ka ikaika hana: ≥275MPa

Elongation: ≥24%, hāʻawi iā ia i ka plasticity maikaʻi a me ka hiki ke deformation.

Hoʻemi ʻāpana: ≥50%

ʻO ka paʻakikī: Ke mālama ʻole ʻia ka wela, ʻaʻole ʻoi aku ka paʻakikī ma mua o 197HB; ʻO ka mālama wela (e like me ka normalizing i 910 ℃) hiki ke hoʻomaikaʻi i kona paʻakikī a me ka ikaika.

Ke kūlana hoʻouna a me ka mālama wela

Hoʻokomo pinepine ʻia ke koʻokoʻo uea hao hao ʻōwili wela SAE1018 i ka mokuʻāina ʻaʻohe mālama wela a i ʻole ka wela wela (annealing, normalizing a i ʻole ka wela wela). Inā makemakeʻia ka hoʻomaʻamaʻa wela, pono e hōʻikeʻia ma kaʻaelike. Inā ʻaʻole i hōʻike ʻia, e hāʻawi ʻia me ka ʻole o ka mālama wela. Hiki i ka Normalizing ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke koʻokoʻo uea kalapona kalapona SAE1018 a hoʻomaikaʻi i kā lākou hana piha.

Nā kahua noi

Ua hoʻohana nui ʻia ke koʻokoʻo uea kila SAE1018 i nā kula he nui ma muli o kāna mau hiʻohiʻona maikaʻi loa:

Mea hana mīkini: Ua hoʻohana ʻia ka uea hao kalapona haʻahaʻa SAE1018 no ka hana ʻana i nā ʻāpana mechanical e like me nā gears, pine, shafts, a me nā pine.

Hana kaʻa: Haʻahaʻa kalapona kila uea SAE1018 i hoʻohana 'ia no ka hanaʻana i ka brake'ōnaehana'āpana, hoʻoili'ōnaehana'āpana, etc., kūpono no ka non-koʻikoʻi haʻawe 'āpana ma luna o nā kaʻa, e like me brackets, papa, etc.

ʻOihana kūkulu hale: Haʻahaʻa kalapona kila uea SAE1018 hoʻohana 'ia no ka hana structural kila, e like me kākoʻo koʻokoʻo, kaola, kolamu, etc.

?Mīkini mahiʻai: Haʻahaʻa kalapona kila uea SAE1018 i hoʻohana 'ia no ka hana mahiʻai mea hana, tractor accessories, etc., kūpono no ka mahiʻai 'āpana mea 'aʻole maʻalahi e pale i ke koʻikoʻi kiʻekiʻe akā, e pono ai ke kapa maikai a me ka corrosion.

?ʻOihana ʻenehana: ʻO ke koʻokoʻo uea kalapona haʻahaʻa SAE1018 i hoʻohana ʻia no ka hana ʻana i nā moku kaomi, pipelines, a me nā mea ʻē aʻe, kūpono no nā lako ʻoihana me kekahi mau koi no ka ikaika a me ka paʻakikī.

?Nā mea hana hale: ʻO ke koʻokoʻo uea kalapona haʻahaʻa SAE1018 i hoʻohana ʻia no ka hana ʻana i nā ʻāpana hana o nā mea hana hale, e like me ke ʻano o loko o nā mīkini holoi a me nā pahu hau.

?Mea hana hana: Haʻahaʻa kalapona uea koʻokoʻo SAE1018 i hoʻohana 'ia no ka hana lima, mea paahana mahiai, a pela aku, kūpono no na mea paahana i ole e koi kiʻekiʻe kiʻekiʻe paakiki a me ka lole pale.
