Nā Pōmaikaʻi o AR Steel?
Hāʻawi ʻo Jindalai Steel i ka pā kila AR ma nā puke nui a liʻiliʻi i nā mea hoʻolālā a me nā mea kanu mea kanu e nānā ana e hoʻolōʻihi i ke ola lawelawe o nā mea koʻikoʻi a hoʻemi i ke kaumaha o kēlā me kēia ʻāpana i lawelawe ʻia. ʻO nā pōmaikaʻi o ka hoʻohana ʻana i ka pā kila pale lole i nā noi e pili ana i ka hopena a/a i ʻole ka hoʻopili ʻana me nā mea abrasive he nui loa.
ʻO ka pā kila pale abrasion ka lōʻihi loa a me ka pale ʻana i nā ʻōpala a me nā ʻōpala. Hana maikaʻi kēia ʻano kila i nā noi koʻikoʻi, a hāʻawi pū kekahi i ka hopena hopena. ʻO ka hoʻohana ʻana i ka pā kila kūpaʻa e kōkua i ka hoʻonui ʻana i ke ola o kāu mau noi a hoʻemi i kāu mau kumukūʻai i ka wā lōʻihi.

Na Waiwai o AR400 A me AR500 Pa'i kila
ʻO AR400 ka "thru-hardened", abrasion resistant, alloy plate. ʻO ka laulā paʻakikī he 360/440 BHN me ka inoa paʻakikī o 400 BHN. He 400°F ka wela o ka lawelawe. Hoʻohana ʻia kēia huahana pāpaʻi no ka hoʻohana ʻana i nā noi kahi e pono ai ke koena maikaʻi o ka formability, weldability, paʻakikī a me ke kūpaʻa abrasion. Kūʻai maʻamau ʻia nā kila kūpaʻa abrasion i ke ʻano paʻakikī a ʻaʻole i kemika paʻa. Loaʻa nā ʻokoʻa liʻiliʻi o ka kemika ma muli o ka wili hana. Hiki i nā noi ke komo i ka hoʻohana ʻana i ka mining, quarries, ka mālama ʻana i nā mea nui, nā wili kila, a me nā ʻoihana pulp & pepa. Hoʻolālā ʻia nā huahana pā lole no nā noi liner; ʻAʻole lākou i manaʻo ʻia no ka hoʻohana ʻana ma ke ʻano he hale kākoʻo ponoʻī a i ʻole nā mea hāpai.
ʻO AR500 kahi pāpaʻa "hoʻopaʻa paʻakikī", pale i ka abrasion. ʻO ka laulā paʻakikī he 470/540 BHN me ka inoa paʻakikī o 500 BHN. Hoʻohana ʻia kēia huahana pāpaʻi no ka hoʻohana ʻana i nā noi kahi e pono ai ke kaulike maikaʻi o ka hopena, ka paʻakikī a me ke kūpaʻa abrasion. Kūʻai maʻamau ʻia nā kila kūpaʻa abrasion i ke ʻano paʻakikī a ʻaʻole i kemika paʻa. Aia nā ʻokoʻa liʻiliʻi o ka kemika ma muli o ka wili hana.

AR400 VS AR450 VS AR500+ Nā Pā kila
Loaʻa paha i nā wili like ʻole nā "mea ʻai" no ke kila AR, akā hāʻawi ʻia nā mea hana i kahi hoʻāʻo paʻakikī - ʻike ʻia ʻo Brinell Test - e hoʻoholo ai i ka māhele i hāʻule ai. ʻO nā hoʻokolohua Brinell i hana ʻia ma nā mea kila AR e hoʻokō maʻamau i nā kikoʻī ASTM E10 no ka hoʻāʻo ʻana i ka paʻakikī.
ʻO ka ʻokoʻa ʻenehana ma waena o AR400, AR450 a me AR500 ka Brinell Hardness Number (BHN), e hōʻike ana i ka pae o ka paʻakikī o ka mea.
AR400: 360-440 BHN maʻamau
AR450: 430-480 BHN
AR500: 460-544 BHN maʻamau
AR600: 570-625 BHN maʻamau (emi maʻamau, akā loaʻa)
