JIS G3125 Qib SPA-C steel phajyog lub siab - zoo huab cua hlau tsim los rau zoo heev atmospheric corrosion kuj. Nws belongs rau JIS G3125 tus qauv thiab yog siv dav hauv kev tsim kho, kev thauj mus los, thiab kev lag luam.
Nws cov ntaub ntawv sib npaug suav nrog GB / T Q345GNHL steel thiab AS WR350/2 steel, ua kom muaj kev sib raug zoo nrog cov qauv thoob ntiaj teb.
Mechanical Properties
JIS G3125 Qib SPA-C steel phaj nthuav tawm cov khoom siv kho tshuab txhim khu kev qha:
Elastic Modulus: 190-210 GPa ntawm 20 degree, muab cov qauv nruj thiab ruaj khov.
Tensile zog: 450 MPa ntawm 20 degree, kom ntseeg tau siab load-cov kabmob muaj peev xwm.
Yield zog: 315 MPa ntawm 20 degree, tso cai rau kev tiv thaiv mus tas li deformation nyob rau hauv kev ntxhov siab.
Elongation (A5): 26% ntawm 20 degree, muab ductility zoo rau fabrication thiab kev tsim kho.
Poisson tus ratio: 0.3, tswj qhov seem stability nyob rau hauv load.
Qhov ceev: 7.8 g / cm³ ntawm 20 degree, raws li tus qauv steel ntom.
Cov ntawv thov tseem ceeb
JIS G3125 SPA-C steel phaj yog qhov zoo tagnrho rau kev siv sab nraum zoov thiab kev lag luam uas tsis kam tiv thaiv atmospheric corrosion yog qhov tseem ceeb. Cov kev siv ib txwm muaj xws li txuas hniav, lub tsev facades, nkoj tsim, ntim, thiab cov tshuab raug rau huab cua.
Peb tuaj yeem muab JIS G3125 Qib SPA-C steel daim hlau nrog tag nrho cov tshuaj muaj pes tsawg leeg thiab cov ntaub ntawv kho tshuab, nrog rau daim ntawv pov thawj zeb. Rau kev nug lossis cov lus hais, peb pab neeg muag khoom tau npaj los muab kev pabcuam sai kom ua tau raws li koj qhov yuav tsum tau ua.
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.
