Siab ZogASTM A588 Daim Ntawv HlauVS A36 daim ntawv me me hauv lub zog. ASTM A588 steel yog HSLA qauv hlau, nce mus txog 50 ksi yam tsawg kawg yog taw tes, nrog cov atmospheric corrosion qhov twg muaj zog thiab siv tau. A36 Cov Hlau Me Muaj Cov Khoom Siv Vuam Zoo Tshaj Plaws nrog rau 36 KSI paib lub zog. A36 cov hlau suav hais tias yog cov hlau me me vim yog tawv.
Siab ZogASTM A588 hlau Lub taisVS A36 cov phaj me hlau hauv corrosion tsis kam. ASTM A588 hlau yog paub zoo rau nws cov huab cua muaj peev xwm.
A588 hlau muaj plaub zaug ntau dua corrosion tsis kam raws li cov hlau me me. Thaum A588 cov hlau nthuav tawm rau cov xwm txheej sab nraud, nws corrosion - cov khoom tiv taus muaj zog ua kom muaj zog dua, txawm tias tsis muaj peev xwm.
ASTM A36 Hlau Phaj thiabASTM A588 Hlau Phajyog ob qho sib txawv specifications rau cov hlau siv hauv ntau yam kev siv. Ntawm no yog qhov sib txawv tseem ceeb ntawm ASTM A36 Hlau Phaj thiab ASTM A588 Rusty Steel Phaj:
Muaj pes tsawg
ASTM A36 Steel phaj: Nws yog cov roj carbon steel uas feem ntau muaj li 0.29% carbon, phosphorus, sulfur, silicon, thiab tooj ua cov khoom seem.
ASTM A588 kub dov corten steel phaj:Nws yog qhov siab - lub zog, qis {{{{{}} aliece} Allomium, npib tsib xee, thiab tooj ua cov khoom siv alloy.

|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0.26% | Tsawg dua los yog sib npaug rau 0.26% |
| Manganese (mn) | 0.80–1.25% | 0.60–0.90% |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.04% | Tsawg dua los yog sib npaug rau 0.04% |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.05% | Tsawg dua los yog sib npaug rau 0.05% |
| Tooj Liab (Cu) | 0.20–0.40% | 0–0.20% |
| Chromium (cr) | 0.40% max | – |
| Npib tsib caug (ni) | 0.40% max | – |
| Lub zog tensile | 485-620 mpa | 400-550 MPa |
| Paib lub zog | 345 mpa min | 250 MPA min |
| Elongation (hauv 8 ") | Ntau dua los yog sib npaug rau 20% | Ntau dua los yog sib npaug rau 20% |
Lub zog thiab cov khoom siv kho tshuab
ASTM A36 Steel phaj: Nws muaj tsawg kawg lub zog ntawm 250 megapualals (MPA) thiab qhov tsawg kawg tensile lub zog ntawm 400 MPA. Nws ua kom pom kev ua kom zoo thiab tuaj yeem yooj yim machined, welded, thiab tsim.
ASTM A588 Weathering Steel Phaj:Nws muaj lub zog siab dua piv rau ASTM A36, nrog tsawg kawg yog lub zog ntawm 345 MPa thiab qhov tsawg kawg tensile lub zog ntawm 485 mpa. Nws muab cov atmospheric zoo heev corrosionance vim nws muaj pes tsawg leeg.
Cov Ntawv Thov
ASTM A36 Steel Plate: It is widely used in general structural applications such as buildings, bridges, and machinery parts.
ASTM A588 CORTEN STEEL Phaj:Nws yog ib qho muaj feem xyuam rau cov qauv sab nraum zoov raug rau cov ntsiab lus, nrog rau cov choj, vaj tse, tsheb thauj khoom, thiab cov tsheb thauj khoom.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov kev sib txawv no nthuav qhia txog cov yam ntxwv tsis sib xws ntawm Astm A36 thiabASTM A588Cov. Thaum xaiv cov qauv hlau tsim nyog rau cov ntaub ntawv tshwj xeeb, nws yog qhov tseem ceeb los xav txog cov phiaj xwm kev cai, thiab sab laj nrog cov kws tshaj lij lossis cov khoom siv steel rau cov khoom siv raug.
