ASTM A606-2 weathering steel tsis yog tsim los yog pom zoo rau kev pabcuam kub.
Vim li cas nws tsis haum rau qhov kub thiab txias
Nws yog ibsiab-lub zog qis- alloy (HSLA) atmospheric weathering steel, optimized rauchav sab nraum zoov-kub siv cov qauv siv, tsis thermal kuj.
Nws cov khoom siv kho tshuab (tshwj xeeb tshaj yog tawm lub zog thiab toughness)poob qis heev ntawm qhov kub thiab txias, ua rau softening, deformation, los yog kev ua haujlwm tsis ua haujlwm.
Cov alloying ntsiab (Cu, Cr, Ni) uas muab nws corrosion kuj nyob rau hauv huab cuatsis muab oxidation kuj los yog creep zogntawm qhov kub thiab txias.
Ntev ntev ntev - qhov kub thiab txias yuav ua rau cov khoom siv microstructure, txo cov kav ntev, thiab tiv thaiv kev tsim patina ib txwm.
Kev txwv kub rau kev siv nyab xeeb
Qhov kub siab tshaj plaws tau pom zoo siv: Nyob ib ncig ntawm 260℃(500℃F)
Saum toj no qhov kub thiab txias, lub zog poob sai heev, thiab nto oxidation ua ntau dhau.
Nws yogtsis ntsuas rau qhov siab tsis tu ncua -kub, nkag, lossis siab- muaj kev pabcuamtag nrho.
Yuav siv li cas rau qhov kub thiab txias
Yog tias koj xav tau siab -kub kev ua haujlwm nrog zoo corrosion kuj, siv:
Thaum tshav kub kub-resistant alloy steels
Stainless hlau (304, 316, 310S)
Boiler lossis siab hlab ntsha steels (xws li, SA-106, SA-240, SA-387)
