Dab tsi yog cov khoom ntawm A672 C55

A672 C55 yog cov qauv txheej txheem rau nruab nrab-kub thiab kev kub siab hluav taws xob welded steel kav hlau kav. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm cov khoom no:

Cov Qauv Qauv

A672: Qhov no yog tus qauv tsim los ntawm American Society of cov neeg kho tshuab engineers (ASME), tshwj xeeb yog hais txog nruab nrab ntawm cov yeeb nkab tshiab thiab muaj kev kub siab electro-melt welded steel yeeb nkab.
C55: Qhov no yog qib ntawm cov hlau, C55 txhais tau tias lub zog tensile ntawm cov hlau yog 550MPA.
