SPA-C steelyog lub siab -zoo atmospheric corrosion-resistant steel. Qhov "C" hauv SPA-C qhia tias nws txias- dov, nrog rau qhov tuab ntawm 0.6 hli txog 2.3 hli.
Piv nrog SPA-H, SPA-C muaj lub zog qis dua me ntsis tab sis tseem muab kev tiv thaiv corrosion zoo thiab kav ntev, ua rau nws tsim nyog rau ntau yam kev lag luam thiab cov qauv siv.
Cov khoomDaim ntawv thov
SPA-C steel phaj yog dav siv hauv engineering machinery, towers, thawv, thiab tsheb. Nws ua ke ntawm corrosion kuj thiab mechanical kev ua tau zoo ua rau nws zoo tagnrho rau cov khoom raug rau sab nraum zoov ib puag ncig los yog atmospheric corrosion.
Cov neeg tsim khoom tsim cov huab cua huab cua hauv Suav teb, suav nrog cov tshuab hlau loj, tuaj yeem muab SPA -C daim hlau hauv ntau qhov tshwj xeeb kom tau raws li qhov yuav tsum tau ua.
Tshuaj muaj pes tsawg leeg
SPA-C steel muaj cov khoom siv ua tib zoo tswj xyuas kom ntseeg tau cov khoom zoo:
Carbon (C): Tsawg dua lossis sib npaug rau 0.12%
Manganese (Mn): Tsawg dua lossis sib npaug li 0.6%
Phosphorus (P): 0.007-0.15%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%
Silicon (Si): 0.25-0.75%
Nickel (Ni): Tsawg dua lossis sib npaug rau 0.65%
Chromium (Cr): 0.30-1.25%
Tooj liab (Cu): 0.25-0.55%
Cov ntsiab lus no txhim khu kev tiv thaiv corrosion, toughness, thiab structural kev ncaj ncees rau sab nraum zoov thiab siab - kev siv kev ntxhov siab.
Mechanical Properties
SPA-C steel muaj kev txhim khu kev qha zoo, nrog rau:
Yield zog Ntau dua los yog sib npaug rau 315 MPa
Tensile zog Ntau dua los yog sib npaug rau 450 MPa
Elongation Ntau dua lossis sib npaug li 26%
Cov khoom no tso cai rau SPA-C steel kom muaj kev ncaj ncees nyob rau hauv cov khoom siv thauj khoom thaum tiv thaiv atmospheric corrosion.
Peb tshwj xeeb hauv kev muab cov hlau tsis zoo hauv huab cua, suav nrog SPA-C, SPA-H, 09CuPCrNi-A, 05CuPCrNi, B480GNQR, Q355GNHD, thiab Q355NHD.
Nrog ntau tshaj 20 xyoo ntawm kev xa tawm, peb tuaj yeem muab SPA-C steel daim hlau ntawm tus nqi sib tw thiab ntau yam tshwj xeeb kom haum rau koj qhov project xav tau.
SPA yog dab tsi -C corten weathering steel phaj sib npaug
Cov qib sib npaug ntawm SPA-C corten weathering steel phaj suav nrog HW350, SPA-H JIS G3125, ASTM A242 (COR-TEN A), ASTM A588 (COR-TEN B), S355J5J5J5WP, S3, S355JOW, S355J2W, 1.8946, 1.8965, SAILCOR IRSM41-97.
SPA -C weathering steel yog dab tsi?
SPA-C yog ib hom atmospheric corrosion-cov hlau tsis muaj zog (Corten steel) tsim rau ntev - lub sij hawm raug sab nraum zoov. Nws tsim ib txheej ruaj khov, tiv thaiv xeb uas tiv thaiv corrosion ntxiv, txo cov kev xav tau ntawm kev saib xyuas.
Dab tsi yog cov ntawv thov tseem ceeb ntawm SPA-C steel?
SPA-C feem ntau yog siv rau architectural facades, sculptures sab nraum zoov, txuas hniav, tuav cov phab ntsa, vaj toj roob hauv pes, thiab cov khoom siv ua haujlwm uas ua haujlwm ntev thiab zoo nkauj yog qhov tseem ceeb.
SPA -C steel puas tuaj yeem welded lossis ua tiav?
Yog lawm. SPA-C tuaj yeem txiav, welded, khoov, thiab tsim siv cov txheej txheem steel txheej txheem. Preheating yuav raug pom zoo rau cov phaj tuab kom tsis txhob vuam tawg.
Kuv tuaj yeem yuav SPA -C steel qhov twg?
SPA-C steel yog muaj los ntawm cov chaw muag khoom tshwj xeeb thiab cov xa khoom. GNEE muaj ntau yam SPA-C cov khoom hauv ntau qhov ntau thiab tsawg.
