S275JR thiab S355JR kub-dip galvanized kav yog ob feem ntau siv hlau. Lawv raug kho nrog kub-dip galvanizing thiab muaj corrosion kuj zoo thiab kev pab lub neej ntev. Lawv tshwj xeeb tshaj yog haum rau lub sijhawm uas yuav tsum tau tiv thaiv cov kua dej tawm xws li cua compressed.
S275JR steel yeeb nkab belongs rau European tus qauv low-alloy high-strength structural steel yeeb nkab, thiab tus qauv siv yog EN10025. Nws cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus carbon ntawm kwv yees li {{10}}.23%, manganese cov ntsiab lus ntawm li 1.5%, silicon cov ntsiab lus ntawm 0.4%, phosphorus cov ntsiab lus ntawm 0.04%, thiab sulfur. cov ntsiab lus ntawm 0.05%. Nws yog dav siv nyob rau hauv structural engineering, tsheb tsim, cia tank thiab ntim, steel qauv tsev, thiab infrastructure engineering.
S355JR zoo ib yam li S275JR, thiab kuj yog ib qho qis-alloy high-strength structural steel yeeb nkab uas siv tib EN10025 tus qauv. Nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab zoo ib yam li S275JR, thiab nws kuj muaj cov khoom siv zoo heev thiab kev sib txuas, uas yog tsim rau ntau yam engineering thiab kev tsim kho.
