ASTM A672 yog dab tsi?
A672 yeeb nkab yog ib qho hluav taws xob (kuj) fusion-welded steel yeeb nkab feem ntau siv rau nruab nrab thiab qis- kev thauj mus los ntawm cov kua dej. Nws cov khoom yog tsuas yog carbon steel, thiab nws yog tsim los ntawm cov hluav taws xob fusion vuam txheej txheem, muab zoo zog thiab siab tsis kam. Hom yeeb nkab no feem ntau siv hauv kev lag luam xws li roj av, tshuaj lom neeg, thiab hluav taws xob hluav taws xob, thiab tsim nyog rau kev xa xov xwm xws li dej, roj, thiab roj.
