ASTM A588 Qib Ayog lub siab -lub zog, qis- alloy (HSLA) cov qauv hlau paub txog nws qhov zoo tshaj plaws atmospheric corrosion resistance, feem ntau hu uahuab cua steel. Thaum raug huab cua kom raug, nws tsim muaj kev tiv thaiv, xeb-zoo li patina uas tshem tawm qhov xav tau kev pleev xim rau ntau daim ntawv thov.
Specification ntawm ASTM A588 Corten Steel:
- Corten Steel Chev:Thickness: 0.5mm-16mm; Dav: 300mm-2000mm
- Corten Steel Phaj / Ntawv:Thickness: 1.5mm-60mm; Dav: 1000mm, 1175mm, 1220mm, 1250mm, 1500mm, 2000mm los yog raws li xav tau; Ntev: 2000mm, 2500mm, 3000mm, 5800mm, 6000mm los yog raws li xav tau.

Cov yam ntxwv tseem ceeb
- Corrosion Resistance: A588 Qib A steel yog qhov muaj zog tiv taus atmospheric corrosion ntau dua li cov pa roj carbon zoo li A36 lossis A572 Qib 50, vim muaj cov ntsiab lus tshwj xeeb alloying, feem ntau tooj liab, chromium, thiab npib tsib xee.
- Siab zog: Nws muaj qhov tsawg kawg nkaus yield zog ntawm 50 ksi (345 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 70 ksi (485 MPa) rau daim hlau txog li 4 ntiv tes tuab, tso cai rau kev sib zog ntawm cov qauv tsim.
- Kev zoo nkauj: Cov txheej txheem oxidation ntuj tsim kom muaj qhov sib txawv thiab zoo nkauj txaus nyiam xim liab - xim av, ua rau nws nrov hauv kev siv vaj tsev.
Tej kev siv
ASTM A588 Qib A feem ntau yog siv rau hauv cov txuas txuas txuas thiab cov tsev tab sis tsim nyog rau ntau cov qauv sab nrauv uas txo cov nqi tu thiab kev ua haujlwm ntev yog qhov tseem ceeb.
- Cov choj thiab hla dhau
- Lub tsev facades thiab structural thav duab
- Rail tsheb thiab kis tau tus yees
- Highway ncej thiab guardrails
- Tank thiab ntim khoom
