America Standard ASTM A588 Corten Steel Plate Piling uye Structural Steel Truss Bridge

ASTM A588 inovhara yakakwirira-yakadzika-yakadzika-alloy structural simbi zvimiro, mahwendefa, uye mbariro dzekuvaka dzakaiswa welded, riveted, kana bolted asi dzakagadzirirwa kunyanya kushandiswa mumabhiriji akaiswa uye zvivakwa uko kuchengetedza huremu kana kuwedzera kusimba kwakakosha.

ASTM A588 isimba repamusoro-yakaderera-alloy structural simbi inotsanangurwa ine simba repamusoro uye yakagadziridzwa mumhepo inodzivirirwa yezvimiro zvesimbi zvimiro zvakaita semakona, chiteshi uye matanda, pamwe nesimbi ndiro nemazariro.ASTM A588 inonyanya kushandiswa ku:
Pedestrian Bridges
Highway Bridge Girders uye zvimwe zvikamu zvebhiriji
Kuvaka ngarava
Matangi
Railcars uye Containers
Fencing
Zvivezwa

Iyo A588 yakatarwa inoitirwa kunyanya kushandiswa mune zvisina kupendwa zvikumbiro, uko kuchengetedza huremu kana kuwedzera kusimba kwakakosha pamwe nehupenyu hurefu nekuda kwekusaora kwayo uye / kana kuwana chitarisiko chinofadza.

Kudzivirirwa kweatmospheric corrosion yeA588 kuri nani pane iyo yekabhoni simbi seA36 neA572-50 ine kana isina yekuwedzera mhangura.Kana yakanyatsogadzirwa uye yakaratidzwa mumhepo, A588 yakakodzera kune akawanda maapplication ari asina pendi mamiriro.

ASTM A588 ine 50ksi shoma yegoho simba uye 70ksi shoma tensile simba.

Classification:
1. High weathering simbi
Yakakwirira yemamiriro ekunze kuramba simbi yesimbi ndeyekuwedzera hushoma hwemhangura, phosphorus, chromium, uye nickel zvinhu kusimbi kuti igadzire danda rekudzivirira pamusoro pesimbi yakaunganidzwa kuvandudza kushanda kwesimbi kurwisa ngura yemhepo.Iwe unogona zvakare kuwedzera huwandu hudiki hwe molybdenum, niobium, Zvinhu zvakaita sevanadium, titanium uye zirconium zvinogona kunatsa zviyo, kuvandudza michina yesimbi, kuvandudza kusimba uye kuoma kwesimbi, kuderedza brittle shanduko yekushisa, uye kuita kuti ive nayo. zviri nani kuramba kune brittle fracture.
2. Weathering simbi ye welding chimiro
Zvinhu zvinowedzerwa kugiredhi resimbi, kunze kwephosphorous, zvakangofanana nepamusoro pemamiriro ekunze kuramba masisitimu, uye mabasa avo akafanana uye anovandudza welding performance.

Features:

Weathering simbi ine hunhu hwekuoma, kutambanudza kwepurasitiki, kuumba, kusungirira uye kucheka, kupfeka kusagadzikana, kupikisa kwekushisa kwepamusoro uye kuramba kuneta kwesimbi yemhando yepamusoro;Kuramba kwemamiriro ekunze ndeye 2-8 nguva yeyakajairwa kabhoni simbi, uye kuita kwekupotera ndeye 1.5 yeyakajairwa kabhoni simbi.-10 nguva, iyo yekupfekedza kuita ndeye 1.5-10 nguva yeyakajairwa kabhoni simbi, inogona kushandiswa kuonda kupfava, kupfekedza kupfekedza kana kupfava kwakapfava.Iyi simbi ine hunhu hwekurwisa ngura, kushomeka kwemarara, hupenyu hwakareba, kuonda uye kuderedzwa kwekushandisa, kuchengetedza basa uye kuchengetedza simba, izvo zvinobatsira vanogadzira zvikamu nevashandisi.Weathering simbi ine nani ngura kuramba mumhepo.Weeathering simbi inogona kutetepa, kufumurwa kana kungopendwa.Simbi yesimbi ine corrosion resistance, kuwedzera kwehupenyu, kuchengetedza kwevashandi, kuderedza kushandiswa uye kusimudzira zvakare inzira itsva, teknolojia itsva uye nzira itsva inogona kubatanidzwa musimbi yemazuva ano, kuitira kuti irambe ichikura nekuvandudza.Simbi system.

Zvakanakira:

Simbi yemamiriro ekunze inogadzirwa nekabhoni simbi yakajairwa ine hushoma hwezvinhu zvinodzivirira kukora semhangura uye nickel.Iine maitiro esimba resimbi, ductility, kuumba, welding, abrasion, kupisa kwakanyanya, kuneta, nezvimwewo;Kupokana kwemamiriro ekunze ndeye 2 ~ 8 yeakajairwa kabhoni simbi Kuita kwekupfekedza kuri 1.5 ~ 10 nguva yeyakajairwa kabhoni simbi, iyo inogona kushandiswa mutete, isina kana kurerutswa coating.Iyo simbi ine hunhu hwekupikisa ngura, kusagadzikana kwemarara uye hupenyu hurefu hwezvikamu, kuonda uye kuderedzwa kwekushandisa, uye kuchengetedza-kushanda uye kuchengetedza simba maitiro, ayo anobatsira vanogadzira zvikamu nevashandisi.

Application:

Kushandiswa kwesimbi yakakwira yemamiriro ekunze ekumisikidza simbi iri nani pane simbi yekupikisa mamiriro ekunze kune yakashongedzerwa chimiro nekuda kweiyo airspheric corrosion resistance.Iyo inonyanya kushandiswa kugadzira, riveting uye welding zvimiro zvemotokari, midziyo, zvivakwa, shongwe uye zvimwe zvimiro.Kana yakashandiswa seyakashongedzerwa zvimiro zvezvikamu, ukobvu hwesimbi haufanirwe kunge hwakakura kupfuura 16mm.Iko kukwenenzverwa kwesimbi yemamiriro ekunze kwesimbi yakashongedzwa iri nani pane iyo yakakwirira yesimbi yemamiriro ekunze, uye inonyanya kushandiswa kune welded zvimiro zvikamu zvemabhiriji, zvivakwa uye zvimwe zvimiro.
