"Weather resistance" yog hais txog qhov tseeb hais tias vim yog cov tshuaj muaj pes tsawg leeg ntawm S355K2G1W, cov hlau daim hlau thiab cov ntawv no muaj kev tiv thaiv siab dua rau atmospheric corrosion piv rau lwm cov ntaub ntawv hlau.
S355K2G1W corrosion-resistant steel ua raws li EN 10155 tus qauv, S355K2G1W cov ntaub ntawv tus lej yog 1.8966.
S355K2G1W weathering steel yog dav siv nyob rau hauv kev tsim kho ntawm sab nraum zoov sculptures, txuas hniav thiab lwm yam loj structural daim ntaub ntawv, marine tsheb thauj mus los, thiab intermodal ntim.
