Dab tsi yog qhov txawv ntawm Q310NQL2 vs SPA-H
Q310NQL2 thiab SPA-H yog ob qho tib si huab cua, tab sis lawv txawv ntawm lub zog thiab cov qauv. Q310NQL2 (GB/T 4171) muaj lub zog tawm los ntawm Ntau dua lossis sib npaug rau 310 MPa, thaum SPA-H (JIS G3125) feem ntau nyob ib puag ncig Ntau dua lossis sib npaug rau 355 MPa.
Ob leeg muaj Cu-Cr-Ni alloy systems rau atmospheric corrosion kuj. SPA-H yog dav siv nyob rau hauv cov thawv thiab tsheb ciav hlau, thaum Q310NQL2 feem ntau yog siv rau hauv cov qauv siv thiab xa tawm engineering.
Dab tsi yog qhov txawv ntawm Q310NQL2 vs ASTM A588 Qib K
Q310NQL2 thiab ASTM A588 Qib K yog ob qho tib si siab -lub zog huab cua steels. Q310NQL2 muab lub zog tawm los ntawm Ntau dua lossis sib npaug rau 310 MPa, thaum ASTM A588 Qib K muaj qib siab dua ntawm Greater dua lossis sib npaug rau 345 MPa.
Ob leeg ua tiav atmospheric corrosion kuj los ntawm Cu-Cr-Ni alloying thiab tiv thaiv xeb txheej tsim. A588 Qib K feem ntau yog siv hauv cov txuas hniav thiab cov qauv hnyav hauv Asmeskas kev ua lag luam, thaum Q310NQL2 tsom rau tus nqi ntau dua -cov qauv tsim thiab kev thauj mus los hauv kev lag luam thoob ntiaj teb.
Kev siv ntawm Q310NQL2 weathering steels
Tsis ntev los no, Gnee tau ua tiav ib pawg ntawm customized Q310NQL2 high weathering structural steel daim hlau rau cov chaw tsim khoom siv tsheb thauj mus los. Cov khoom tau ua tiav raws li cov neeg siv khoom xav tau hauv cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw, thiab qhov tseeb qhov ntev.
Q310NQL2 yog kub- dov / txias- dov atmospheric corrosion resistant steel. Los ntawm kev ntxiv cov ntsiab lus alloying xws li Cu, Cr, thiab Ni, nws cov huab cua ua haujlwm tau zoo dua qub. Nws atmospheric corrosion kuj feem ntau yog 2-4 npaug siab dua li cov pa roj carbon zoo tib yam.
Nyob rau hauv cov av noo, tshuaj tsuag ntsev, thiab cov chaw ua haujlwm hauv huab cua, nws tuaj yeem tsim cov txheej txheem tiv thaiv xeb, uas txuas ntxiv lub neej kev pab cuam los ntawm kwv yees li 1.5-2 zaug (lossis txhim kho cov kav ntev li 30-50%), thaum txo cov nqi kho thiab rov ua dua tshiab. Hauv kev xyaum ua engineering, tag nrho cov nqi tu lub neej tuaj yeem raug txo los ntawm 20-40%. Cov khoom no yog siv dav hauv tsheb ciav hlau, cov thawv thauj khoom, thiab cov khoom siv thauj mus los hauv nroog uas raug rau lub sijhawm ntev -cov kev pabcuam sab nraum zoov.
Vim nws cov txheej txheem alloy nyuaj, Q310NQL2 yuav tsum muaj kev tswj xyuas nruj ntawm smelting purity, TMCP (Thermo-Mechanical Controlled Processing), thiab nto zoo, uas qhov chaw siab dua ntawm kev ruaj ntseg ntau lawm.
Txhawm rau daws cov teeb meem kev lag luam no, Gnee siv cov txheej txheem tshuaj lom neeg nruj thiab ua kom zoo dua qub, ua ke nrog cov txheej txheem TMCP tswj kev dov thiab cua txias kom ua kom zoo dua microstructure thiab txoj hauv kev txias. Kev tshuaj xyuas ntau qhov chaw thiab hauv - cov txheej txheem tswj kev ua tau zoo kuj tau siv los ua kom lub zog zoo ib yam, tawv, thiab kev ua haujlwm huab cua.
Yog tias koj tab tom nrhiav rau huab cua huab cua zoo rau cov tsheb ciav hlau, ntim khoom, lossis cov khoom siv thauj mus los, Gnee tuaj yeem ntseeg siab muab Q310NQL2 siab huab cua cov qauv hlau daim hlau nrog rau qhov ntau thiab tsawg, kev pabcuam kuaj, thiab xa tawm - qauv ntim. Thov qhia koj qhov yuav tsum tau ua, thiab peb yuav muab cov khoom tsim nyog tshaj plaws nrog rau kev tshaj lij thiab kev txhawb nqa hauv 24 teev.
