Q460NH thiab Q500NH yog Suav tus qauv (GB/T 4171) siab -lub zog, qis- alloy weathering (Corten) steel daim hlau paub rau zoo heev atmospheric corrosion kuj, tsim ib tug ruaj khov, xeb-zoo li txheej tiv thaiv, ua rau lawv zoo tagnrho rau cov qauv xws li txuas hniav, railways, thiab sculptures 4. "500" qhia qhov tsawg kawg nkaus qhov muaj zog (hauv MPa) rau cov ntu nyias, muab cov weldability zoo thiab cuam tshuam rau kev siv sab nraum zoov architectural thiab structural applications.

Cov yam ntxwv tseem ceeb & kev sib piv
Hom: Ob leeg yog weathering steels (Corten steel), tsim los tsim kev tiv thaiv patina, txo kev txij nkawm.
Lub zog: Lawv yog siab - lub zog steels; Q460NH muaj qhov tsawg kawg nkaus yield zog ntawm 460 MPa (rau cov phaj nyias), thaum Q500NH muaj qhov siab tshaj tawm lub zog ntawm 500 MPa (rau cov phaj nyias).
Txuj: Txhais los ntawm Tuam Tshoj tus GB / T 4171 tus qauv, nrog rau lwm qib zoo li Q355NH, Q550NH, thiab lwm yam.
Khoom: Zoo weldability, qis-kub tej yam toughness, zoo heev yas forming, thiab abrasion kuj.
Daim ntaub ntawv: Sab nraum zoov sculptures, txuas hniav, railway kev tsim kho, architectural facades, ntim, thiab lwm yam sab nraum zoov qauv yuav tsum tau durability thiab aesthetic thov.
Lub zog muaj zog: Q500NH muaj zog dua Q460NH, haum rau cov ntawv thov xav tau kev thauj khoom ntau dua -cov kabmob muaj peev xwm lossis cov khoom nyias nyias.
Daim Ntawv Thov Niche: Txawm hais tias ob qho tib si ua haujlwm zoo sib xws, qhov kev xaiv nyob ntawm qhov kev xav tau tshwj xeeb lub zog thiab tsim qauv.
