Tus nqi zoo ntawm DX52D yog dab tsi?
A: ① Tsawg tus nqi ua haujlwm: Siab ductility, tsawg seem seem; ② Tsawg corrosion tiv thaiv tus nqi: Tsis xav tau kev tiv thaiv corrosion theem nrab, kev pab lub neej ntev; ③ Tag nrho cov nqi-effectiveness yog siab dua stainless hlau thiab txhuas alloy, haum rau loj- nplai lub tsev cladding.
Dab tsi yog qhov txawv ntawm DX52D thiab DX51D?
A: DX52D muaj zoo formability (elongation ≥26% vs DX51D ≥22%), haum rau complex dabtsi yog khoov / sib sib zog nqus kos duab; DX51D muaj tus nqi qis, tsim nyog rau kev tsim cov xwm txheej yooj yim; DX52D yog qhov kev xaiv zoo tshaj plaws rau lub tsev cladding.
Dab tsi yog lwm cov ntaub ntawv rau DX52D?
A: ① Tib theem: DX53D (zoo formability, tus nqi siab dua); ② Tus nqi qis: DX51D (tsim yooj yim); ③ Siab corrosion kuj: Zinc-aluminium-magnesium coated DX52D, xim-coated steel ntawv; ④ Cov xwm txheej tshwj xeeb: Stainless hlau (muaj zog corrosion), aluminium alloy (lub teeb yuag).
Dab tsi yog cov khoom kuaj rau DX52D? A: ① Mechanical zog: yield zog, tensile zog, elongation; ② Corrosion tsis kam: galvanized txheej hnyav / tuab, ntsev tsuag tsis kam (tsis muaj ntsev tsuag ≥48 teev); ③ Kev tsim cov khoom: kev sim khoov, ntsuas khob; ④ Cov tsos: qhov sib txawv ntawm qhov sib txawv, qhov zoo.
Cov ntaub ntawv pov thawj zoo rau DX52D suav nrog dab tsi?
A: Cov ntaub ntawv pov thawj uas tau muab los ntawm steel zeb, suav nrog rau lub tshuab hluav taws xob, batch tooj, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, galvanized txheej hnyav, thiab cov qauv siv tau; Cov ntaub ntawv tuaj txawv teb chaws xav tau daim ntawv pov thawj EN 10346, thiab cov khoom siv hauv tsev yuav tsum ua raws li GB / T 2518 cov cai.
