STAINLESS STEEL COMPOSITION
Lub koom haum American Hlau thiab Hlau tau ua qhov kev tshawb fawb tob uas ua rau cov npe yooj yim ntawm cov hlau tsis muaj hlau muaj pes tsawg leeg. Cov npe no yog hu ua "tus qauv hom." Cov hom no tau raug xaiv los ntawm kev txiav txim siab metallurgical tom qab txiav txim siab ntau yam xws li cov lus ntuas ntawm engineering thiab specification sau lub cev, nrog rau cov kev xav tau ntawm cov kev pabcuam tub rog. Cov txheej txheem ntawm kev tsim qauv no tau coj mus rau kev txheeb xyuas los ntawm hom raws li ntau pawg, siv cov txheej txheem yooj yim ntawm cov lej thiab qee zaum cov ntawv. Hauv 3 tus lej, thawj tus lej qhia cov koob lossis pawg, thiab ob tus lej kawg qhia txog hom. Kev hloov kho ntawm hom yog qhia los ntawm cov ntawv txuas ntxiv. Cov npe series qhia cov pawg hauv qab no:
