1. Intrinsic Atmospheric Corrosion Resistance tseem nyob ruaj khov
Txias dov yog ib chav -kub lub cev deformation txheej txheem uas tsuas ua rau grain distortion thiab ua hauj lwm hardening ntawm cov hlau. Nws tsis hloov cov tub ntxhais Cu/Cr/P weathering alloy muaj pes tsawg leeg ntawm SPA-H, los yog cov ntsiab lus thiab kev faib ntawm corrosion-resistant precipitates nyob rau hauv lub matrix. Txias-rolled SPA-H ua tib yam tuab thiab ruaj khov tiv thaiv patina li kub-rolled SPA-H, nrog rau qhov zoo ib yam ntev-lub sij hawm atmospheric corrosion ntawm 0.01–0.03 mm/xyoo.
2. Smooth nto txhim kho kev sib haum xeeb ntawm kev tsim Patina pib
Cov txheej txheem txias dov tshem tawm cov nplai zeb ntxhib thiab oxide txheej ntawm qhov kub ntawm -rolled SPA-H, uas ua rau ib tug du, tiaj tus thiab tsis xws luag -dawb nto. Qhov no tsis txhob muaj qhov tsis sib xws hauv cheeb tsam oxidation tshwm sim los ntawm qhov chaw tsis xws luag nyob rau theem pib ntawm kev tawm sab nraum zoov, ua kom muaj kev tiv thaiv patina nucleates thiab loj hlob zoo ib yam ntawm tag nrho cov hlau nto.
3. Tsis muaj qhov kev pheej hmoo ntxiv hauv cheeb tsam Corrosion raug nthuav tawm
Ua hauj lwm hardening thiab sab hauv residual stress generated thaum lub sij hawm txias dov tsis hloov lub electrochemical zog ntawm SPA-H steel matrix. Nyob rau hauv ib txwm atmospheric thiab me me ntug dej hiav txwv ib puag ncig, cov txheej txheem yuav tsis induce rhiab hauv zos corrosion xws li intergranular corrosion, pitting corrosion los yog crevice corrosion.
4. Me Edge Corrosion Potential yog yooj yim Mitigated
Qhov tsuas yog me ntsis corrosion kuj yog los ntawm cov ntse txiav ntug ntawm txias- dov daim hlau, uas yuav dhau los ua ib ntus micro-corrosion pib cov ntsiab lus vim muaj kev ntxhov siab. Qhov kev pheej hmoo no tuaj yeem raug tshem tawm tag nrho los ntawm kev tshaj tawm yooj yim - kev ua haujlwm xws li ntug sib tsoo, chamfering lossis deburring, thiab yuav tsis cuam tshuam rau tag nrho corrosion kuj ntawm steel phaj.
