High Carbon steels TIG ER70S-3 Foob ua
Haum rau boiler, chemical thawv, machinery, kev tsim kho, shipbuilding thiab lwm yam lag luam, rau siab dua cov kev xav tau ntawm cov uas tsis muaj carbon steel thiab tsawg alloy structural steel vuam.
Tus qauv peb tau ntsib: GB/T39280 W 49A/P 5 3, AWS A5.18 ER70S-3 & A5.18M E49S-3, ISO636-A:W 42 4 2Si, ISO636-B: W 49A/P 4 3.
Dab tsi yog cov
yam ntxwv?
●Cov xaim pub mis yog du, lub arc yog ruaj khov, kev sib sau zoo nkauj.
●Lub molten hlau fluidity yog qhov zoo, qhov txaws yog tsawg, muaj cov txheej txheem vuam zoo heev.
●Cov ntsiab lus ntawm S thiab P yog tsawg hauv cov hlau fused.
●Uas tau zoo heev plasticity, cuam tshuam toughness thiab HIC / SSC kuj.
