ʻO ka haku mele SM520pā kilaʻO ka nui o ke kalapona (C), silika (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), molybdenum (Mo) a me nā mea ʻē aʻe. I waena o lākou, ʻo ke kalapona ka ʻāpana iwi o ke kila, hiki ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī o ke kila, akā e hōʻemi ana i ka plasticity a me ka paʻakikī o ke kila. Hiki i ka silikoni a me ka manganese ke hana i nā hoʻonā paʻa me ke kalapona, e hoʻonui ana i ka ikaika a me ka paʻakikī o ke kila me ka mālama ʻana i kona plasticity a me ka paʻakikī. Hiki i ka Phosphorus a me ka sulfur ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke kila a hoʻomaikaʻi i ka pale ʻana o ke kila. Hoʻomaikaʻi ʻo Chromium a me nickel i ka pale ʻana o ke kila, ʻoi aku hoʻi i nā kaiapuni moana. Hiki i ka Molybdenum ke hoʻomaʻemaʻe i nā hua kila a hoʻomaikaʻi i ka hana holoʻokoʻa o ke kila. Pono e hoʻomaopopo ʻia ʻo nā hiʻohiʻona haku mele nā mea koʻikoʻi e pili ana i nā waiwai mechanical a me ke kūpaʻa corrosion oSM520 pā kilas, no laila pono lākou e hoʻoponopono e like me nā hoʻohana like ʻole a me nā kūlana kaiapuni e hoʻokō i nā pono o nā hiʻohiʻona noiʻi like ʻole.

SM520 pā kilaloaʻa i ka ikaika kiʻekiʻe a me ka ikaika tensile a hiki ke hoʻokō i nā koi o nā hale lawe ukana nui.

SM520 mea hoʻohui kemika:

C: ≤0.2 Si: ≤0.55 Mn: ≤1.65 P: ≤0.035 S: ≤0.035

Mechanical waiwai o SM520:

Ka ikaika hua: ≥365MPa Ka ikaika tensile: 520-640MPa Elongation: ≥19% 0 degere hopena ikehu: ≥47

ʻO ka pā kila SM520 he paʻakikī maikaʻi, hiki ke pale i nā ukana hopena nui, a ʻaʻole hiki ke haʻihaʻi.

SM520pā kilahoʻohana nui ʻia no Nā Alahaka, nā pahu, nā mīkini ʻeli, nā moku, nā hale mana, nā kaʻa, nā pahu mālama aila, nā ipu a me nā mea hana welded ʻē aʻe e halihali ana i nā ukana ikaika.

Loaʻa i ka pā kila SM520 ka hana hoʻoponopono maikaʻi a hiki ke hoʻohana ʻia no ka ʻokiʻoki, kulou, wili a me nā hana hana ʻē aʻe.

Loaʻa i ka pā kila SM520 ka hana wiliwili maikaʻi a hiki ke hoʻokō i nā koi o nā kaʻina hana wili

Loaʻa i ka pā kila SM520 ke kūpaʻa ʻino maikaʻi a hiki ke kū i ka corrosion ma nā ʻano ʻino like ʻole no ka manawa lōʻihi. ʻO ka pale ʻana i ka corrosion ka hiki i kahi mea ke pale aku i ka corrosion i loko o kahi pōʻino a he hōʻailona koʻikoʻi o ke ola lawelawe o ka mea. Hōʻike ka pā kila SM520 i ke kūpaʻa corrosion maikaʻi ma nā wahi corrosive e like me ke kai moana a me ka lewa ʻoihana, a hiki ke hoʻonui i kona ola lawelawe.

SM400/SM490 Hot rolled steel plate/sheet hoʻohana mau ʻia ma ke kahua aʻe.
(1) SM400 Hot rolled steelused no ka metala, mechanical, uila kūkulu kahua
(2)SM490 Hoʻowili kila i hoʻohana ʻia no nā moku, hana pūʻali koa (pale kaua).
(3) SM400/SM490 palapala kila/pepa i hoʻohana ʻia no ka ʻenekinia waho, kahua paahana mīkini, kaʻa hope o nā huahana.
